+## Abstract
+A maxillary sinus lift procedure is indicated if a dental implant needs to be placed in the posterior maxilla with limited bone available to accommodate a dental implant. Both open and closed sinus lifting procedures are reliable approaches for increasing the bone volume needed to support proper implant positioning. However, these methods can lead to several complications. In addition to the general complications commonly linked to oral surgery, such as swelling or hematoma, the primary complication in open sinus lifting is typically the perforation of the Schneiderian membrane during osteotomy. Detailed and extensive presurgical evaluation is crucial to minimize such complications. The objective of this study was to delineate contemporary trends in sinus lift surgery, with a specific emphasis on different techniques of sinus lift procedure, anatomical and surgical factors, presurgical evaluation, bone grafting, and the practical implications of these factors in implant dentistry cases involving a deficient posterior maxilla. In conclusion, while both osteotome and lateral window techniques can assist clinicians in addressing the complexities of implant placement in a deficient posterior maxilla, bone height before implantation remains a critical factor in determining the success and longevity of implants.

+## Introduction and background
+The maxillary sinus is the largest among all the paranasal sinuses [1]. Two types of bone resorption occur when patients lose their maxillary posterior teeth. The first type is centripetal resorption, which is a natural result of the bone remodeling process following tooth loss. The second type is resorption, caused by the pneumatization of the sinus cavity towards the alveolar crest [2]. Both types of resorption often lead to a reduced amount of bone available for placement of dental implants, necessitating a regenerative procedure known as a maxillary sinus lifting procedure. Sinus lifts are regarded as a safe treatment option with a lower risk of complications [3,4]. The primary goal of this intervention is to create enough bone height and width to facilitate the proper placement of dental implants. This goal can be achieved using either a one-stage or two-stage technique. The one-stage technique inserts dental implants simultaneously with the sinus augmentation procedure. With the two-stage technique, bone augmentation is performed during the initial surgical procedure, and the dental implants are placed later once the necessary bone volume has been established [5].
+The traditional sinus lift procedure, initially explained by Tatum H [3,6] in the 1970s, involved a combination of incisions. This combination included a crystal incision along with mesial and distal vertical incisions, allowing for the elevation of a buccal flap to expose the outer bone wall of the sinus. Subsequently, a trapdoor osteotomy (window) was made in the lateral bone wall, providing access to the Schneiderian membrane and the sinus cavity. Schneiderian membrane is a membrane that forms the lining of the inner aspect of the maxillary sinus. The membrane was then meticulously dissected and lifted in an apical direction, with particular care taken to preserve its integrity. This displacement of the membrane created space for the graft material. Bone replacement grafts in maxillary sinus lift procedures encompass a variety of materials. These include autologous bone, which can be sourced from the mandibular ramus, chin, iliac crest, or other intraoral locations, as well as bone substitutes, synthetic biomaterials, or combinations of these substances [7,8].
+In cases where patients have sufficient remaining bone height, it is possible to augment the sinus floor using a less-invasive method known as the trans-alveolar approach, which involves the use of the osteotome technique. This technique, first employed by Summers RB [7] in 1994, allows sinus floor augmentation without the need for extensive surgery. However, complications are possible during maxillary sinus lift surgery. The most frequently encountered intraoperative complication in maxillary sinus lift procedures is the perforation of the sinus membrane. Other potential complications include postoperative infection, sinusitis, graft exposure, graft loss, edema (swelling), seroma formation (accumulation of fluid), bleeding, and membrane exposure [9-12]. The objective of this study is to review the maxillary sinus lift procedure, encompassing preoperative assessment, surgical techniques, bone grafting materials, and possible complications.
+## Review
+Anatomy
+The maxillary sinus holds approximately 12-15 mL of air in adults [13]. It has a pyramidal shape, with its base near the nasal cavity, the upper part serving as the orbital floor, and the tip toward the zygomatic bone [14]. An oval or slit-shaped drainage opening, known as the ostium, functions as an overflow opening and is positioned in the upper part of the inner wall [14,15]. The space between the semilunar hiatus and the nasal floor can range from 18 to 35 mm, with an average of 25.6 mm [16]. The position of the ostium minimizes the chances that it will be blocked during augmentation procedures [17]. The base of the maxillary sinus extends from the premolar or canine region anteriorly and to the maxillary tuberosity posteriorly, often reaching its lowest point near the first molar area [18]. In dentate adults, the maxillary sinus floor is the thickest of its walls and lies approximately at the same level as the nasal floor. However, in patients who have lost their teeth (edentulous), it is typically situated about 1 cm below the nasal floor. Septa within the sinus is composed of cortical bone and can be found both horizontally and vertically within the sinus floor [19,20]. Some studies have observed septa in approximately 25%-31.7% of maxillary sinuses [21,22], and these septa can range from 2.5 to 12.7 mm in length and be in various locations within the maxillary sinus [11]. Notably, there tend to be more septa in edentulous or atrophic (reduced in size) ridges than in partially edentulous or nonatrophic arches [19,21].
+Blood supply and innervation
+The primary branches of the maxillary artery, which supply blood to the bony walls and membrane of the sinus, include the posterior superior alveolar artery, inferior orbital artery, greater palatine artery, and sphenopalatine artery. It is essential to note that the locations of the inferior orbital artery and the posterior superior alveolar artery are crucial considerations in surgical planning, as any damage to these arteries can result in bleeding complications [23,24].
+These two arteries eventually join together, forming a dual arterial arcade that encircles the maxillary sinus [25]. This connection can occur in either an extraosseous manner, typically located about 23-26 mm away from the alveolar ridge, or an endosseous fashion, positioned approximately 16.4-19.6 mm from the alveolar margin [24]. It is noteworthy that the dental branch of the posterior superior alveolar artery consistently exhibits an endosseous connection with the inferior orbital artery in all dissected anatomical cases; however, this connection is visible on radiographs in only 50% of cases [25-27].
+The innervation of the maxillary sinus is outlined in Table 1. It represents a distinct connection between the venous system of the maxillary sinus and the cavernous sinus, which is significant because it can potentially serve as a pathway for infections spreading from the sinus to the brain [28-30]. Table 1

+Presurgical evaluation
+The presurgical evaluation is preliminarily done through CT or cone-beam computed tomography (CBCT) scans. This evaluation determines essential parameters such as membrane thickness, presence of sinus septa, residual bone height, and presence of teeth. The elevation of the maxillary sinus floor carries a risk of jeopardizing the sinus physiology, and a careful and thorough CBCT evaluation before the procedure can reduce the chances of intra-operative and post-operative complications [31,32]. The maxillary sinus is considered healthy when the mucous composition is normal, mucociliary clearance is efficient, and the sinus ostium is patent. These criteria are significant because a healthy maxillary sinus is less likely to develop postsurgical complications, even in the event of a small procedural error, such as a minimal perforation [33].
+Risk of perforation
+The risk of perforation can be associated with irregularity in the membrane thickness, sinus septa, the angle between the buccal and palatal wall, and existing tooth implants or tooth roots adjacent to the sinus [34].
+The Schneiderian membrane
+The Schneiderian membrane is an important parameter during the presurgical analysis [35,36]. Membrane thickness of up to 2 mm is considered physiological and favorable; however, thickness exceeding 5 mm is associated with sinus ostium obstruction. Recent CBCT studies indicate that 1 mm is a physiological value and 4 mm is pathological [37-40].
+Sinus septa
+In approximately 38% of all cases, sinus septa (or Underwood's septa) are found inside the maxillary sinus. Depending on their shape, position, and development, they may threaten membrane integrity during sinus floor elevation, and the presence of these anatomical variations can enhance the risk of perforation [17,38,41]. The development of Underwood's septa should be considered in judging the complexity of sinus floor elevation during surgery. If the sinus septum runs transversely, surgery is straightforward, but if it is longitudinal or incomplete, the procedure may become more difficult during membrane elevation [42].
+Alveolar-antral artery
+An intraosseous anastomosis, the alveolar-antral artery, is always present between the posterior superior alveolar artery and the infraorbital artery. However, an extraosseous anastomosis exists in only 44% of cases. Hemorrhage of the alveolar-antral artery is a common complication in sinus lifting procedures. To avoid this, a posterior approach to the bone antrostomy has been suggested. Planning should include a careful evaluation of CBCT to ascertain the course of the artery. Another important consideration is the artery's diameter. If the diameter is less than 1 mm, or if the artery cannot be detected radiographically, the likelihood of severe complications during surgery is minimal. Conversely, if the diameter is 2-3 mm or greater, the risks of hemorrhage and the need to ligate the artery increase [34]. Both the diameter and course of the artery are evaluated through CBCT, as shown in Figure 1 [43].Figure 1

+Presence of teeth
+The resorption of the alveolar ridge and the maxillary sinus pneumatization are both profoundly influenced by the loss of posterior teeth [44]. When a close relation between the sinus membrane and tooth roots has been detected, especially in the case of a single posterior missing tooth, the perforation risk increases [45]. However, the probability of perforation decreases when two adjacent teeth are missing. This decreased probability could be due to the presence of sinus pneumatization in a small area with an irregular sinus floor shape. Figure 2 shows the relationship between the extraction of teeth and pneumatization of the maxillary sinus [46].Figure 2

+Residual alveolar ridge height
+Residual alveolar ridge height has been suggested to significantly influence membrane thickness [47] and the success of implant therapy over time [9]. Alveolar ridge height also plays a major role in implant survival rates [48]. According to some studies [49,50], a pre-implant bone height of less than 5 mm is associated with a decreased survival rate. These findings indicate that a higher success rate could be achieved with greater alveolar bone height.
+General considerations
+Generally, sinus lifting is indicated with a residual bone height of 10 mm or less (including leaving a space of 1 to 2 mm of bone between the implant apex and the sinus floor level) [48]. The two basic methods for the sinus lifting procedure are the trans-alveolar (crestal osteotome) and the lateral window [51]. If more than 5 mm of bone height is present, the crestal osteotome is the treatment of choice [52]. However, if the ridge height is severely reduced, the use of a lateral window is indicated. This technique can aid in achieving a height of up to 9 mm, which is enough to compensate for the bone shortage [48]. Factors affecting the prognosis of the maxillary sinus lifting procedure are demonstrated in Table 2.Table 2

+Surgical techniques
+The maxillary sinus lift procedure has gained widespread acceptance to reduce postoperative complications in cases of limited bone height in the posterior maxillary alveolar ridge [48]. This procedure is typically advised in cases with bone height in the posterior maxilla of 10 mm or less [53].
+Tatum H [54] introduced the initial lateral window procedure in 1975. This technique involves surgically creating an opening in the lateral wall of the sinus and then gently lifting the Schneiderian membrane to facilitate placing the implant(s) of suitable length. The use of the lateral approach is particularly valuable in cases of substantial bone deficits because it allows an increase in vertical bone height by more than 9 mm [48]. The osteotomy can be executed by utilizing either a high-speed handpiece or precise piezoelectric instruments. Using a piezoelectric tip to prepare the window greatly reduces the likelihood of membrane perforation and results in an overall safer procedure [54-56].
+In 1994, Summers RB [7] was the first to employ the osteotome approach. This technique involves a transalveolar elevation of the maxillary sinus floor. This approach offers several advantages, including efficient surgical procedures, reduced surgical duration, fewer complications, lower postoperative discomfort, and increased patient satisfaction. Furthermore, the osteotome approach typically increases vertical bone height from 3 to 9 mm [52,57,58].
+To optimize the results of lifting the maxillary sinus, various minimally invasive strategies have been developed to provide an increased level of patient satisfaction [48]. The antral membrane balloon elevation is a minimally invasive approach designed to gradually lift the Schneiderian membrane while ensuring its preservation. The membrane is carefully separated by applying gentle and sustained pressure while inflating a latex balloon. This method is considered relatively safer, with minimal postoperative bleeding, pain, or discomfort [59,60]. Large-scale longitudinal studies are required to establish the procedure's clinical effectiveness and long-term outcomes [61].
+Recently, a new bioactive kinetic screw bone implant model efficiently accomplishes both autogenous grafting and sinus augmentation while also securing the implant in a single procedure. When the vertical bone height in the planned implant site is less than 4 mm, an additional surgical step is undertaken to harvest bone and enhance its availability [62-66]. Experimental studies conducted on synthetic maxillary bone and sinus have successfully demonstrated the feasibility and simplicity of this innovative technique. However, more studies are needed to further evaluate this technique [67].
+The selection of the appropriate surgical technique for sinus lift procedures primarily depends on the height of the existing pre-implant bone. The transcrestal approach tends to be preferred when the residual bone height is greater than 5 mm. In cases where the residual bone height is 5 mm or less, the lateral window approach is considered more suitable [7,58,68-70].
+Bone grafting materials
+Bone grafts can be used to promote bone formation and maxillary sinus augmentation can be accomplished through the use of autografts, allografts, xenografts, alloplastic material, and growth factors [71]. Autogenous grafts obtained from the same individual are considered the gold standard because of their osteogenic capacity and osteoconductive and osteoinductive properties. Autogenous grafts also heal quickly and have strong resistance to infections. However, the increased morbidity and unpredictable reabsorption associated with autografts have led to the development and use of synthetic substitutes. Allogenic grafts, obtained from another individual in the same species, have only osteoconductive and osteoinductive capabilities. Xenografts, obtained from different species, possess only osteoconductive capability. Alloplastic grafts, whether natural or synthetic, are solely osteoconductive biomaterials [51,72]. Adding xenografts to autogenous grafts improves volumetric stability in the sinus augmentation procedure [73]. All graft types can be prepared in different forms, such as large blocks or streaky gels. Some authors have suggested performing sinus lift procedures without grafting materials by utilizing coagulated blood as a scaffold to form new bone. However, this technique was not evaluated alongside appropriate control procedures, and the results were not reproducible [4]. A different approach was introduced in managing cases using platelet-rich plasma or plasma rich in growth factors, with or without grafting biomaterials. The preparation of platelet-rich plasma involves the use of citrate in blood samples to prevent coagulation and maintain a liquid form. To prepare the gel form, thrombin and/or calcium chloride are added to induce fibrin polymerization [74]. Platelet-rich fibrin is considered a second-generation platelet concentrate, offering additional advantages such as enhanced healing capabilities, low cost, and ease of handling. Platelet-rich fibrin can improve new bone formation, and significant results can be obtained after a sinus lift procedure [75]. The use of platelet-rich fibrin can also improve implant stability and the osseointegration process [76]. Platelet-rich fibrin is currently a trend in the management of sinus lift procedures and is considered superior to first-generation concentrates [77].
+Complications of maxillary sinus lift procedure
+Just as with any other surgical procedure, a sinus lift is associated with various complications, including intraoperative complications, acute postoperative complications, and chronic postoperative complications [78].
+Intraoperative Complications
+Common complications that can occur during maxillary sinus graft surgery are the perforation of the Schneiderian membrane, penetration into the sinus or nasal cavity, bleeding, damage to the adjacent teeth, bone fracture, perforation of the alveolar bone, inadequate initial implant stability, incorrect placement or alignment of the implant, blockage of the opening to the maxillary sinus, and accidental swallowing of surgical instruments [78].
+Tearing of the Schneiderian membrane: Tearing of the Schneiderian membrane is the most frequently encountered complication during maxillary sinus graft procedures. The incidence of this complication falls within the range of 20%-44% when the lateral window approach is used [51]. Ardekian L et al. [79] reported that perforation of the sinus membrane happened in 85% of cases with a residual ridge measuring 3 mm, whereas in cases with a 6-mm residual ridge, membrane perforation only occurred in 25% of cases. Minor perforations may not necessitate treatment, but in the event of a significant perforation, the procedure should either be halted, or a collagen membrane should be applied to repair the perforation. If the procedure is stopped, a subsequent attempt should not be made for another 4-6 months [10].
+Bleeding: The maxillary sinus region contains a network of blood vessels, with the primary vessel being the maxillary artery. This artery gives rise to multiple branches, including the intraorbital artery, the anterior superior palatine artery, and the posterior superior alveolar artery, that supply blood to the sinus cavity and the adjacent tissues and structures. Numerous connections (anastomoses) are typically observed between the posterior superior alveolar artery and the infraorbital artery within the lateral bony wall of the sinus. These connections play a crucial role in ensuring adequate blood circulation in this region [80]. Bleeding can occur if arteries are damaged during the preparation of the lateral window. To mitigate this risk, it is advisable to identify the location of the artery prior to surgery using CBCT [2]. To address a severed vessel, various methods have been suggested, including applying strong pressure, directly tying off the vessel, introducing particulate bone graft into the arterial canal, using bone wax, smoothing the area with burs, and employing electrocautery. Additionally, having the patient sit upright can help reduce blood flow by 38%, aiding in the control of bleeding [28].
+Acute Postoperative Complications
+Immediate postoperative complications include discomfort, inflammation, swelling, infection affecting both the surgical area and the sinus, sinusitis, bone loss, bleeding, bruising around the mouth and nose, and hematoma (particularly hemosinus). Other potential issues include the presence of emphysema, wound opening, graft loss, fixture displacement or loss, the formation of an oroantral fistula, benign paroxysmal positional vertigo, and transient or permanent numbness in the palate [78].
+Chronic Postoperative Complications
+While implant periapical lesions are infrequent in the maxilla, they can arise in clinical situations in which excessive heat is generated during the drilling process. When the bone is assessed as hard, a longer time gap (at least one minute) between drilling stages is advised. Additionally, utilizing chilled saline instead of the standard room-temperature saline solution can be beneficial [78].
+## Conclusions
+In conclusion, maxillary sinus augmentation is an effective preprosthetic method for enhancing the edentulous posterior maxilla. A thorough presurgical evaluation of sinus anatomy significantly lowers the likelihood of complications. Using growth factors and stem cells is a promising technique to improve graft maturation time, although additional clinical research is required to fully assess their advantages.

+## Full Text
+## Introduction and background
+The maxillary sinuses are air-filled cavities located behind the cheeks and above the upper teeth. When teeth are lost, especially in the posterior maxilla, the bone that once supported them tends to shrink over time, leaving inadequate bone for stable implant anchorage. This limitation can compromise the success of dental implant treatment in these areas. Maxillary sinus augmentation addresses this issue by effectively increasing the bone volume and density in the posterior maxilla, creating a more favorable environment for the placement of dental implants. By elevating the sinus membrane and adding bone graft material beneath it, this procedure augments the bone height and width in the area, providing a stable foundation for dental implant placement.
+The augmentation graft of the maxillary sinus was a crucial component of implant-directed maxillary reconstruction for over three decades [1]. Maxillary sinus augmentation, also known as sinus lift surgery, has evolved significantly over the years, from its early inception as a bone augmentation procedure pioneered by Tatum in the 1970s to the refined and sophisticated techniques utilized today. This procedure plays a pivotal role in creating a stable foundation for dental implants in the posterior maxilla, where bone quality and quantity are often compromised.
+This article serves as a comprehensive exploration of the various maxillary sinus augmentation techniques currently employed in clinical practice. By delving into the intricacies of these techniques, we aim to provide a nuanced understanding of their principles, indications, advantages, and potential complications. Furthermore, we will highlight recent advancements and emerging trends that are reshaping the landscape of maxillary sinus augmentation, paving the way for improved outcomes and patient satisfaction. Through this exploration, we will elucidate the rationale behind each technique, ranging from lateral window and crestal approaches to innovative minimally invasive methods such as hydraulic sinus condensing and balloon sinus elevation.
+The goal of the present article is to give an outline of the fundamental principles of maxillary sinus reconstruction, comprising the physiology and anatomy of the sinus, preoperative assessment, surgical signs, surgical procedures, and management strategies for issues.
+## Review
+Anatomy and physiology
+The maxillary sinuses are a pair of air-filled cavities located in the bilateral maxillae that are situated laterally to the nasal cavity, inferior to orbital floors, superior to maxillary teeth, and anterior to the infratemporal fossa (as shown in Figure 1).Figure 1
+## Coronal view of the ostiomeatal complex. The uncinate process lies in a sagittal plane. The maxillary sinus ostium drains into the infundibulum.
+Source: Stern and Green (2012) [2]; reproduced with permission from Elsevier
+The average volume of these sinuses is 12.5 mL, making them the biggest of the paranasal sinuses [3]. The maxillary sinuses are coated by the Schneiderian membrane, which is composed of a cell cambium layer (osteogenic periosteal layer) on the bone sides and ciliated respiratory epithelium (pseudostratified columnar epithelium) on the lumen side. The infraorbital nerve travels through the middle of the maxillary roof in a posterior-anterior direction. The floor of the canal is usually made up of thick bone, although, in a few instances, it may be absent, leaving just a thin mucosal layer between the sinus cavity and nerve [4]. The sinus ostium is situated on the medial wall of the nose above the uncinate procedure, and it communicates with the ethmoid infundibulum in the middle meatus on the walls of the nose. Bony, thin septae that span from the lateral to medial sinus wall might be found in up to 37% of people, with 45.9% in the middle, 22.5% in the third anterior, and 31.5% in the posterior sinus. One or two septae are found in 89% of individuals with septae [5].
+The position as well as the presence of septa in the maxillary sinuses may have an impact on the treatment plan, and if they are not identified before the surgery, it can cause perioperative complications. This will be reviewed in detail later. The cilia of the Schneiderian membrane play a vital function in guiding the discharge of mucus and debris toward the ostium, thereby maintaining constant drainage in normally functioning sinuses. Certain medical conditions may increase the risk of chronic sinusitis in some patients. Allergic rhinitis can cause inflammation of the mucosa close to the ostium, resulting in inflammation and obstruction of mucous discharge, causing painful sinus pressure and stagnant fluid infection. Dysfunctional sinus cilia can cause a buildup of mucus and debris, which can cause infection since the sinuses are unable to remove the debris and regular discharge [6].
+Indications and contraindications of sinus augmentation
+The main reason for performing a sinus graft surgical procedure is to prepare for posterior maxilla implant reconstruction that has suffered from bone loss after tooth extraction and sinus pneumatization. In such cases, the bone has become too atrophic to support implants (as shown in Table 1). Sinus graft surgery is appropriate for a range of cases, including single-tooth as well as multi-tooth reconstruction and complete reconstruction of the posterior maxilla in edentulous patients.Table 1

+Single-tooth edentulous space with >8 mm of bone remaining
+Open sinus lift via lateral maxilla sinus antrostomy or closed (crestal approach) osteotome technique; immediate implant placement
+Preoperative assessment
+A detailed dental, as well as medical history and physical examination, must be conducted prior to initiating maxillary sinus augmentation surgery. It is important to note any relevant positive history, like the latest upper respiratory disease, chronic sinus as well as sinusitis, otitis media, facial pain, past sinus or nasal surgery, prior maxillary reconstruction efforts, and smoking history. Studies have revealed that the complication risk for smokers who undergo sinus lift grafts is comparable to that of the common population, although there is an indication that smokers who have implants embedded in sinus transplanted bone have a greater rate of failure in comparison to non-smokers [7,8]. A preoperative CT scan is advised to evaluate the volume of bone already present, exclude preexisting sinus illness, and detect any bony septae [9].
+Informed consent
+Before beginning the maxillary sinus grafting surgery, it is crucial to have an informed consent discussion with the patient. This discussion should cover the benefits, risks, alternatives to the process, and the risks of alternatives. Common risks related to the procedure comprise bleeding, pain, swelling, graft failure, infection, and sensory changes to the second branch of the cranial nerve (V). It is important to note that smokers have a greater risk of implant failure, despite the potential success of the graft method. The eventual restoration of the edentulous maxilla is the main advantage of the procedure. The treatment can be substituted with a shorter implant, a three-unit bridge, zygomaticus implants, partial dentures, or angled implants. The risks of the alternatives should also be discussed. The patient must understand that the surgery is elective and that the decision to proceed is solely theirs after considering all the possible options. The expected timeframe for dental restoration after the procedure may exceed a year, and additional costs may be incurred. To help the patient understand the informed consent process, multimedia resources such as patient education videos, models, and radiographs can be used.
+Surgical techniques
+According to recent studies, maxillary sinus augmentation may be achieved using two techniques: the sinus intrusion osteotomy technique and the lateral window technique. These approaches for vertical augmentation in the oral cavity are regarded as the most reliable ones. These procedures can be carried out using many bone graft substances, comprising autogenous bone, xenograft, alloplastic, and allograft substances. Autogenous bone is thought to be an ideal graft for the sinus lift procedure because it offers enough feasible bone to initially support the implant and promote osseointegration [10]. Recent research has revealed that autogenous bone grafts are the better way because they maintain a sufficient alveolar ridge height for five to 10 years after initial insertion [11]. To enhance the amount of bone inserted into the maxillary sinus, demineralized freeze-dried bone may be combined with autogenous bone. Studies have revealed that adding demineralized freeze-dried bone to autogenous bone marginally reduces the level of bone attained; nevertheless, this change is insignificant clinically because the implants are still enclosed by bone [10].
+Autogenous bone grafts are reflected to be unique as they contain endosteal osteoblasts, which give them the capacity to form bone directly. Along with osteoblasts, a corticocancellous graft also releases growth hormones and bone morphogenic proteins (BMPs), which promote the production of new bone [12]. The proximal tibia, calvarium, anterior iliac crest, and maxillofacial areas are a few anatomical locations that can be used to harvest bone transplants. These methods, however, are outside the purview of this essay, so we will not go into more detail about how they work.
+Several sites, including the maxillary tuberosity, ramus, symphysis, mandibular third molar site, and posterior maxilla, can be harvested for intraoral bone. Even though maxillary tuberosity provides a smaller amount of bone (1-2 mL), it is located in a similar surgical field as the lateral technique for the maxillary sinus and should be considered [13]. In the posterior maxilla, toward the hamular notch, a crestal incision is made to obtain the graft, along with any necessary vertical releasing incisions. The incision is prolonged posteriorly to reach the tuberosity when the maxillary sinus is to be accessed via the lateral window technique. The posterior maxilla is shown by raising a full-thickness mucoperiosteal flap, which enables precise bone harvesting with a rongeur. During the procedure, it is crucial to prevent pterygoid plates, maxillary sinus, molar teeth, and a larger palatine canal to prevent complications (see Figure 2).Figure 2
+## A bone graft composite is packed into the sinus site. After approximately six months, implants are placed, followed by a final restoration after another six months.
+Source: Stern and Green (2012) [2]; reproduced with permission from Elsevier
+The symphysis is the location that produces the most intraoral bone [14]. To gain access to this area, a canine-to-canine vestibular incision must be made at least 3 mm from the mucogingival junction. The periosteum is raised, and the osteotomy is made 10 mm below the incisor tooth’s apex.
+A trephine with a collecting instrument positioned along the suction line is an appropriate instrument for bone harvesting. The cortical plate may be eliminated if required, and the bone marrow can be extracted (Figure 3). During the procedure, the mental nerve must be avoided, and the patient should be made aware of the enhanced hazard of V3 paresthesia brought on by this method. Related to this, bone can be extracted from the third molar sites in the mandible and posterior maxilla using a scraping tool by collecting a container coupled to the suction.Figure 3

+Tatum first demonstrated the lateral window technique by utilizing a modified Caldwell-Luc method [15]. In this surgical approach, osteotomies are used to create a bone window that is then either removed or turned medially without rupturing the membrane of the sinus. First, a posterior superior alveolar nerve block, a superior anterior alveolar nerve block, and palatal infiltration are used to administer local anesthesia with epinephrine. A local anesthetic may be utilized in conjunction with general anesthesia or intravenous sedation, if necessary. Steroids and antibiotics are often given as preventative measures prior to the surgery, although the decision to use perioperative steroids and antibiotics should be at the discretion of the surgeon. Before beginning the procedure, it is uncertain whether preoperative administration of medication is beneficial or not. Therefore, the surgeon should carefully weigh the potential risks and benefits before administering such drugs. Before performing the incision, the patient is instructed to rinse his mouth with a 0.12% chlorhexidine solution.
+From maxillary tuberosity to the position immediately anterior to the anterior edge of the sinus, the crestal incision is created. In order to expose the sinus without impairing the sinus window, vertical releasing incisions should also be performed on the anterior and posterior sides to the depth of the vestibule. The maxilla lateral wall should then be revealed by elevating a full-thickness mucoperiosteal flap (Figure 4). Next, four linear osteotomies should be performed using a #6 or #8 round bur, starting with the inferior horizontal osteotomy, which must be performed as near to the sinus floor as feasible, a maximum of 2-3 mm above the floor, and extending posteriorly from the region of the first or second tooth to the anterior edge of the maxillary sinus (Figure 5).Figure 4

+During the procedure of performing osteotomies, it is crucial to use a gentle touch and a brushing stroke to prevent any damage to the Schneiderian membrane. When carrying out the procedure in the presence of bicuspid teeth, extra care should be taken to avoid causing any harm to them, and the osteotomy must be limited to 4 mm from the distal aspect of the tooth. The next step involves performing the superior horizontal osteotomy at a height where augmentation is planned. Finally, the posterior and anterior vertical osteotomies are formed to connect the inferior and superior osteotomies. The osteotomies must run parallel to the lateral wall of the nose and the anterior edge of the maxillary buttress (or maxillary tuberosity), respectively (Figure 6).Figure 6

+When the window is formed and the membrane is visible, any attached bone is taken out or rotated medially. If the bony window is rotated inwardly, it develops the floor of the maxillary sinus. To elevate the Schneiderian membrane, the process should begin by lifting the margins with caution and then progressively increasing the elevation. Over-elevation of one area should be avoided, as it can lead to perforation. The use of broad-based curettes or freers is recommended for membrane elevation. If possible, the membrane should be raised greater than the superior osteotomy. It is essential to lift the Schneiderian membrane above the superior osteotomy to avoid undue strain on the bone graft substance (Figure 7).Figure 7

The posterior ostectomy should be at the corner of the maxillary buttress. The anterior ostectomy should be adjacent to and parallel to the lateral wall of the nose, and the superior ostectomy should be at the height of the intended graft.

+Sinus membrane perforation is possible during the procedure, which can lead to complications (Figure 8). Small perforations may not require treatment, but large ones should be patched with a collagen membrane, or the procedure should be aborted. If the treatment is unsuccessful, it should not be repeated for at least four to six months. After raising the membrane, bone graft material is positioned anteriorly and inferiorly beneath it, making sure not to overpack it (Figure 9). To account for volume loss, an extra 20% of bone graft material must be injected. After that, the mucoperiosteal flap is moved and sutured. Six months following the sinus lift treatment, implants can be inserted if there is enough alveolar bone to support them, and bone graft substance can be packed around them (Figure 10). Patients should be prescribed postoperative antibiotics and decongestants for two weeks and advised to take sinus precautions such as not blowing their nose and coughing or sneezing with their open mouth.Figure 8

+Piezoelectric technology is an ultrasonic tool utilized for making osteotomies. This scheme has a higher power than traditional ultrasonic instruments, enabling the creation of osteotomies in thicker, more compact cortical bone without cutting soft tissue. The benefit of this system is to decrease the hazard of perforating the sinus membrane. The piezoelectric tool may also help in the rise of the sinus membrane, especially in robust areas of thin membranes and bone. This system has various inserts, from osteotomes to diamond-cutting inserts to those that aid in lifting the sinus membrane. To elevate the membrane, the endosteum is separated from the bone, and the piezoelectric cavitation is subjected to the hydropneumatic pressure of a physiological saline solution (Figure 11) [16].Figure 11

+A research study conducted by Vercellotti et al. [17] involved creating 21 bony window osteotomies in 15 patients using the Mectron Piezosurgery System with inserts that had a vibration from 60 to 210 mm and power exceeding 5W. Every osteotomy was carried out while being irrigated by a surgical system pump. After the flap was reflected, the bony window was formed by a piezoelectric scalpel, and then the membrane elevator tip was utilized, beginning at the apex and moving to the distal and mesial aspects. Attention was focused on the sinus floor, where the membrane was raised to limit the harm of perforation. In this study, all sinus augmentations utilized autogenous bone grafts and platelet-rich plasma. The research found just one membrane perforation in 21 patients, yielding a success rate of 95%.
+The sinus intrusion osteotomy is recommended for cases where there is a minimum of 5-6 mm of alveolar bone available. This method was demonstrated to increase bone height by 4-8 mm, but it is best suited for situations where having enough bone for implant stabilization and minimal bone height are required [18]. In 1994, Summers [19] originally reported the method, which entails creating a crestal incision, bone prepping, and raising the sinus by a few mm. During the procedure, not only is bone compacted apically and the sinus elevated, but bone is also compacted laterally with progressively larger osteotomes (Figure 12).Figure 12
+## Trephined bone core partially intruded into the sinus cavity

+During the procedure described by Summers, a crestal incision is made, and implant drills are utilized to construct an osteotomy, leaving 1 mm of bone within the sinus membrane and site. Then, sequential osteotomes of progressively increasing diameter are utilized to determine the depth of the desired implant length, compacting bone apically and laterally, and elevating the sinus membrane. Once the required diameter and length are achieved, the bone graft substance is put in the prepared site’s apical portion (Figure 13). The implant is located at the desired length, ensuring its stability. The main closure is then completed by adding a cover crew. The healing abutment can be connected to the implant, and it can be exposed after four to six months of healing. Similarly, Komarnyckyj and London [20] also observed a 95.3% success rate when performing this process on 16 patients and placing 43 implants. This study demonstrated a mean bone increase of 3.25 mm throughout the follow-up period of nine to 47 months.Figure 13

+BMP is an option for bone graft material for enhancing the maxillary sinus, which is gaining popularity in the field. BMPs are altering growth factors that have bone-inductive characteristics, and two recombinant human proteins, rhBMP-7 and rhBMP-2, are currently available [21]. BMPs offer several advantages over bone graft materials, including no morbidity at the harvest site, ease of use, increased soft tissue healing, and the ability to be used in people who are not candidates for autogenous grafts [10]. BMPs come in powder form and can be mixed with sterile water and applied to the carrier during surgery. Collagen is the most commonly used carrier material for maxillary sinus augmentation, but it does not have mechanical strength and should be utilized in an area with borders in every dimension [10]. The preferred method for utilizing BMP-2 for maxillary sinus augmentation is the lateral window approach, although there is limited evidence for its success with the sinus intrusion osteotomy technique. The procedure involves administering local anesthesia, making an incision, raising a full-thickness mucoperiosteal flap, creating bony osteotomies, and elevating the sinus membrane as earlier described. If a perforation in the membrane occurs, it is not mandatory to repair it when using BMP-2, but the surgeon may choose to do so. The BMP is provided in lyophilized powder form and reconstituted using sterile water, following the manufacturer’s instructions. The reconstituted BMP is loaded into a sterile syringe and applied evenly to the collagen sponge (Figure 14). It takes at least 15 minutes to let the liquid settle so that the BMP adheres to the sponge before it is cut into 15-mm strips and located among the bony floor and membrane of the sinus (Figure 15). Chromic gut sutures are used to achieve primary closure.Figure 14

+A one-week course of antibiotics is prescribed, and the patient is advised to take sinus precautions. The patient must be notified about the likelihood of significant swelling. A postoperative panoramic radiograph may be taken after four months to assess bone formation, and implants may be located six months prior to the process. Boyne et al. [22] conducted an early study that demonstrated the successful usage of rhBMP-2 in 12 patients who received the material in their maxillary sinus. The average bone height was 8.51 mm. The most common postoperative adverse impacts were facial swelling, pain, redness, and rhinitis.
+Implants were inserted in the increased sinuses 12 weeks later and permitted to integrate for three months, in accordance with research comparing rhBMP-2 to anterior iliac crest grafts in 30 rabbits [23]. The rhBMP-2 group saw the largest mean vertical bone growth, and both groups’ bones had comparable quality, according to the research. It is essential to highlight, however, that recombinant BMP is contraindicated in individuals with hypersensitivity to proteins, carriers, or any other formulation substances. In addition, it should not be applied to people who have active cancers or are receiving cancer treatment, to those who have tumors that have already grown or been removed, to skeletally immature people, to women who are pregnant, or to people who have active infections. Patients who do not demand a separate way to get bone graft material may find that BMP is a good alternative.
+Postoperative instructions and management
+After surgery, it is important to provide patients with both printed and oral instructions regarding postoperative care. The patient should be advised to avoid consuming rough or hard foods, which can damage sutures and cause wound dehiscence. Additionally, sinus precautions should be taken, which include avoiding any activity that can result in sudden pressure variations in the sinus, like sneezing and nose blowing. If the patient needs to sneeze, they should do so with an open mouth to direct pressure away from the sinus. It is important to inform the patient about common postoperative symptoms, such as soreness, which is normal as well as expected for numerous days post-surgery. According to the postoperative instructions, it is common for a few patients to go through bleeding from the surgical incision for up to 24 hours after the sinus lift surgery. However, this bleeding may seem worse than it is because it can mix with saliva. The instructions advise that the patient should swallow the blood rather than expectorate it. If the bleeding becomes bothersome, it can be controlled by direct wet gauze pressure. If the bleeding persists after two uses of gauze for every hour or if the volume is concerning, the patient must notify the doctor. In addition, occasional skin bruising and swelling are normal after a sinus lift surgery.
+Complications and their management
+Schneiderian membrane perforation is the most frequent complication of maxillary sinus lift surgery (Table 2). In prospective observational, uncontrolled research, 70 patients had a total of 212 implant loadings after undergoing 81 sinus lifts. A total of 44% of sinuses have been intraoperatively perforated, but they were healed, and the operation was finished without difficulties. Moreover, 2% of sinuses experienced perforations so severe that the treatment had to be terminated. Furthermore, 33% of perforations were found in sinuses where septae were visible on preoperative radiographs, and 52% of the sinuses with septae were perforated. Two of the 36 holes were so serious that the surgery had to be terminated.Table 2

+Common treatments for sinus perforation involve doing nothing if the perforation is <2 mm in diameter and placing a slowly resorbing collagen membrane if the perforation is >2 mm in diameter. In one patient who presented with acute sinusitis following implant placement, postoperative complications involved the extrusion of a graft into the sinus cavity. Following medical as well as surgical remedies, the infection cleared up, and implants were restored. Persistent peri-implantitis and a peri-implant cyst were among the issues that arose later. Importantly, even though membrane perforations have been linked to postoperative complications like local infection, pain, and swelling, there is no correlation between intraoperative perforations and long-term implant survival. This research revealed an overall survival rate for seven years of 95.5% for implants implanted in grafted sinuses. Noteworthy is the fact that five of the nine unsuccessful implants were implanted in heavy smokers. Instances of chronic infections resulting in severe sinusitis and the potential for graft extrusion, exposure, and/or failure are uncommon. Treatment usually depends on the symptoms that are currently present and may include antibiotics, drainage of surgical debridement, or a Caldwell-Luc technique [24-26].
+## Conclusions
+The maxillary sinus lift is a widely accepted standard treatment for edentulous maxillas, having been in use for the last 30 years. A very frequent occurrence is pneumatization of the maxillary sinus as a result of posterior maxillary tooth loss. Significant maxillary atrophy prohibits implant insertion in this location. Sinus augmentation was utilized for decades to prepare these areas for dental implant insertion.
+Transalveolar and lateral antrostomy procedures are the two most common methods for enhancing posterior maxillary vertical bone height. The clinical and radiographic evaluations identify the most appropriate treatment strategy for every clinical condition. Both methods were demonstrated to have greater success rates. There are few absolute contraindications to the sinus lift procedure, with most being relative contraindications. However, practitioners must be well versed in how to address them. Adequate preparation, knowledge, and experience make maxillary sinus augmentation and elevation a beneficial process for patients, with an expected outcome.

+## Abstract
+Clear aligner treatment is a novel technique in current orthodontic practice. Distinct from traditional fixed orthodontic appliances, clear aligners have different material features and biomechanical characteristics and treatment efficiencies, presenting new clinical challenges. Therefore, a comprehensive and systematic description of the key clinical aspects of clear aligner treatment is essential to enhance treatment efficacy and facilitate the advancement and wide adoption of this new technique. This expert consensus discusses case selection and grading of treatment difficulty, principle of clear aligner therapy, clinical procedures and potential complications, which are crucial to the clinical success of clear aligner treatment.

+## Full Text
+## Introduction
+Malocclusion is a common oral disease with the estimated prevalence among general population ranging from 43.5% to 67.2%.1,2 It is associated with the risk of various oral dysfunctions and esthetic concerns, which may have detrimental effects on mental health and the quality of life.3–6 Recent years have witnessed the growing popularity of clear aligners among patients owing to their esthetic appeal, comfort, and convenience in oral hygiene maintenance.7,8 However, as a novel technology distinct from traditional fixed orthodontic appliances, clear aligner treatment (CAT) presents new challenges in case selection, treatment strategy, aligner design, and follow-up monitoring, which are associated with the differences in material characteristics and properties, and treatment outcomes.9–12 Therefore, key clinical aspects of CAT are demanded to help improve treatment efficacy and promote continued development and dissemination of this clinical technique.Clear aligners are removable orthodontic appliances that were first introduced two decades ago and have been used to treat nearly 20 million patients worldwide. Since their launch, significant innovations have been achieved in the development of clear-aligned materials. The use of big data analyses and design software has enabled the aligners to tightly envelope the tooth surface and apply gentle continuous force which can be designed based on the desired tooth-specific movement direction and distance. The optimal sequence of tooth movement can be calculated precisely to ensure that tooth moves in the desired direction.9,13 Furthermore, clinical solutions have evolved from optimizing individual to optimizing group teeth movement, while clinical indications have expanded from simple to complex cases, including surgical cases.14–16Consequently, CAT has become the primary innovating trend in orthodontics.14,17 To date, over 5000 publications on clear aligners have been indexed on PubMed, including case reports, clinical trials, retrospective clinical studies, and reviews, highlighting the on-going interest in this field.18–22 The purpose of this expert consensus was to summarize the core technology of CAT and provide clinical guidance for practitioners in terms of indications, treatment strategies, aligner design, and follow-up monitoring.
+## Case selection and grading of treatment difficulty
+## Indications and contraindications
+The current indications for CAT are comparable to those for fixed orthodontics. Clear aligners can be used to treat nearly all types of malocclusions, especially the patients with high esthetic and comfort requirements, poor periodontal conditions, susceptibility to caries, or enamel developmental defects. However, clear aligners are not recommended for patients with clinically short crowns, requiring extensive mesial movement of the posterior teeth, or showing poor compliance.20However, treatment difficulty of clear aligner therapy varies greatly among cases. Thus, we suggest difficulty-grading criteria for CAT.
+## Grading of treatment difficulty
+Clear aligners are made of elastic materials, and teeth are moved by the rebound force generated by the elastic deformations of the aligner materials when the aligners are positioned.7 Thus, aligners mainly provide a “pushing force”, and their clinical efficiency varies among different types of tooth movements (Fig. 1).23–27 Therefore, it is crucial to accurately assess treatment difficulty and select most suitable cases.Fig. 1
+Predictability of different tooth movements achieved through clear aligner therapyWe developed the CAT-CAT difficulty assessment tool,28 which assigns scores based on model analysis, X-ray examination results, and clinical examination results. According to the literature and authors’ clinical experience, clinical cases were divided into four grades: easy, moderate, difficult and challenging (Table 1).Table 1

+## Principles of clear aligner therapy
+Different from traditional fixed orthodontic appliances, clear aligners are made of elastic materials, which cover the whole or partial clinical crowns and create a “pushing” force produced from material deformation of the clear aligners. Thus, theoretically, the force can be designed to exert onto any part of the tooth crowns as long as it is closely covered by the aligners. Thus, the crowns’ surface area and the fitness of the aligners are the key points to the success of treatment. Attachments used in clear aligner treatment are bonded on the crowns, which can not only increase the surface area but also afford more action points of the force. Attachments in various shapes and sizes can be designed to supplement clear aligners for different biomechanical demands.Besides, as we know, several types of arch wires made from different materials and in different shapes and/or sizes are used in traditional fixed treatment. In general, arch wires are used from thin to thick, round to rectangular, Niti to stainless steel, and therefore soft and flexible to solid and stable during the treatment. By doing so, teeth movement can be controlled in a predicted way. However, in clear aligner treatment, for each brand, the same aligner material is used throughout the whole aligner treatment, which is not as flexible as Niti wire nor as stable as stainless-steel wire. Thus, to move individual and/or group of teeth, tooth movement need to be designed in a stepwise mode, according to the natures of specific tooth movements.Moreover, aligners’ elastic force is directly proportional to the amount of material deformation within a certain range, whereas excessive deformation can lead to plastic deformation, resulting in a loss of the force. Additionally, all the elastic force decreases with the deformation time.9 Therefore, when designing clear aligners, a series of intermediate statuses is used to bridge the initial and final status. The aligners are regularly replaced, helping the teeth move gradually to the desired position under the effect of a continuous gentle force (Fig. 2).Fig. 2
+A schematic illustration of the principles of clear aligner therapy for incisor retraction in a premolar-extraction case. A final set-up is designed based on the initial set-up and a final aligner is fabricated based on the final tooth set-up. The final aligner is topologically distinct from the pre-treatment dentition and should be elastically stretched for being fitted onto the dentition. The stretched aligner on the pre-treatment dentition is activated and generate retraction force on the anterior teeth and protraction force on the posterior teeth, resulting in premolar-extraction space closureThus, the initial, intermediate and final positions are the three keys to the success of clear aligner therapy. The initial position is determined based on patients’ characteristics, especially the digital dental models that capture the intraoral dentition and occlusion. Intermediate positions aim to ensure that the path and rate of tooth movement comply with the biological and biomechanical principles of orthodontic tooth movement. The ideal final position necessitates well-aligned dental arches, normal anterior overjet/overbite, and perfect posterior interdigitations.Therefore, CAT is essentially a process of tooth repositioning in three dimensions. A critical aspect of this process is the acquisition and redistribution of space. There are currently five main methods for gaining space: arch expansion, molar distalization, incisor proclination, interproximal reduction (IPR), and extraction.29–32 Clinical treatment plans should be designed based on individual cases.Next, we will discuss specific strategies for various clear aligner treatments in details, based on the methods of gaining space.
+## Clinical procedures of clear aligner treatment
+As illustrated in Fig. 3, clear aligner treatment encompasses nine procedures in clinical practice, starting from diagnosis, clear aligner treatment difficulty assessment based on CAT-CAT, acquisition of digital models and aligner treatment planning. Once the aligner treatment planning is ready, aligner fabrication ensues. Then, clear aligner treatment progresses to clinical section that involves fitting of initial set of aligners, follow-up appointments and monitoring, and end of the active clear aligner treatment. Lastly, retention is required and important following orthodontic treatment.Fig. 3
+The overview procedures of clear aligner treatment
+## Diagnosis
+The precise initial position of the teeth requires complete and accurate patients’ data. And thus, data collection for CAT is essential, including facial and intraoral photographs, radiographic data [panoramic tomography, cephalometric radiographs, and cone beam computed tomography scans (CBCT)], and digital dental models that can be obtained through silicone rubber (PVS) impressions or intraoral scanning.33,34 Based on these patient data, a meticulous diagnosis is established.
+## CAT-CAT aligner difficulty assessment
+Orthodontic treatment goals are similar, regardless of treatment modalities. CAT plans should be based on patient complaints, presentation, and diagnosis. CAT can make orthodontic treatment easier, faster and more effective. However, before patients can be recommended for CAT treatment, difficulty level should be assessed (Table 1) to ensure patient suitability. And clinicians should ensure that they have made the correct diagnosis and appropriate treatment plans.28 As for some difficult or challenging cases, such as patients with severe periodontitis or needing surgical treatment, multi-disciplinary treatment (MDT) and specialists’ guidance are necessary.
+## Digital models
+As mentioned above, digital models can be acquired through either intraoral scanning or PVS impression taking.
+## Aligner treatment planning
+Recently, we developed a novel clear aligner treatment philosophy—biomechanics-guided, esthetics-driven, periodontium-supported and temporomandibular joint-compatible clear aligner therapy (BEPT-CAT)—that can guide practitioners to perform aligner treatment planning.35 Most cases of malocclusion are caused by “incorrect” tooth position, resulting in the discrepancies in necessary and available space. And thus, the treatment principles focus on either increasing the amount of space available or reducing the tooth amount. Common clinical methods for increasing the available space include arch expansion, molar distalization, and incisor proclination, while methods for reducing the tooth amount include IPR and extraction.36,37
+## Arch expansion
+## Indications
+Narrow dental arch: a narrow dental arch can be determined based on the relationship between the most prominent points on the buccal surfaces of the crowns of the lower posterior teeth and the Wala ridge.38 Pont index analysis and Howes value can also assist in the width assessment.39 Pretreatment CBCT can be used to clarify the spatial relationship between the root and alveolar bone, which helps avoid excessive expansion that may result in bone fenestration or dehiscence.Excessive buccal corridor: excessive buccal corridor refers to excess negative space between the dental arch and the buccal mucosa of the oral cavity. Previous studies have shown that an excessive or insufficient buccal corridor jeopardizes smile esthetics.40,41 An excessive buccal corridor is indicative of the arch expansion.
+## Considerations for final position design
+Factors that must be considered include arch symmetry, arch coordination, and appropriate expansion amount to prevent bone fenestration or dehiscence. The volume of basal bone on buccal side should be analyzed in CBCT to determine the upper limit of the expansion. The amount of up-to-2 mm expansion on each side is safe in most cases. As for adolescents, the greater regenerative potential of alveolar bone remodeling makes arch expansion much safer. To prevent buccal inclination of crowns during expansion, the final position design should ensure that all the expanded posterior teeth are in lingual inclination (from the lateral view, the palatal cusps are invisible) (Fig. 4).42Fig. 4
+Aligner treatment planning for arch expansion. a A narrow upper arch is to be expanded. b From the buccal view, the palatal cusps of the molars can be observed (yellow arrows). c From the posterior view, the palatal cusp (yellow arrow) is more occlusal than the buccal cusps. d Buccolingual angulation of the molar is modified and a buccal root-torque is added. e The palatal cusps cannot be observed from the buccal view
+## Attachment design
+Attachments are required on the buccal surfaces of teeth during arch expansion to prevent buccal inclination. For teeth with inadequate height of lingual cusps, lingual attachments may be placed simultaneously.43
+## Considerations for staging
+It is recommended to design a staged expansion for any expansion exceeding 1 mm unilaterally, such as a “V-pattern” design like molar distalization. Homonymous teeth in the same jaw are suggested to expand simultaneously because they can act as reciprocal anchorages.By adhering to these principles, clinicians can effectively incorporate arch expansion into clear alignment treatment plans, ensuring optimal outcomes in patients with dental arch discrepancies.
+## Molar distalization
+## Indications
+Almost normal facial pattern with distal (Class II) or mesial (Class III) molar relationship may be an indication for molar distalization. It may be accompanied by mild to moderate crowding, deep overjet, or an anterior crossbite/edge-to-edge bite. However, molar distalization is not generally recommended for neutral molar relationship (Class I).44,45Sufficient space in the posterior dental arch is necessary for molar distalization. CBCT evaluation from a three-dimensional perspective is recommended for molar distalization greater than 2 mm. Vertically, the presence of a low maxillary sinus increases the difficulty of upper molar distalization, especially when the molar roots penetrate the cavity. Third molar extraction is recommended to reduce distalization resistance and provide more space.44,46
+## Considerations for final position design
+The upper limit of molar distalization of clear aligner treatment depends on the available retromolar space. The third molars can be extracted if there is no sufficient space. The amount of less than 2 mm molar distalization on one side is considered predictable in most cases while the mesio-distal inclination of posterior teeth and the potential of bone growth in children and adolescents should be taken into consideration.Based on the literature and clinical experience, the predictability of molar distalization using clear aligners is approximately 88%.23 Thus, it is feasible to design the final position based on the actually required distalization distance (i.e., to obtain a neutral relationship) where no or minimal overtreatment is required. Additionally, to prevent labial fenestration and/or dehiscence in the lower anterior region, it is necessary to avoid labial movement of the lower anterior teeth, particularly the roots. This is because class II intermaxillary elastics are commonly applied during upper molar distalization, which exert a mesial force on the lower arch and labially push the lower anterior teeth.47
+## Attachment design
+Molar distalization does not require the supplement of attachments. However, attachments are recommended to enhance the grip of teeth with short crowns. Moreover, molar distalization is often accompanied by other complex movements such as intrusion and rotation, and attachments are usually required to improve the success rates of these movements and prevent off-tracking. Traditional rectangular attachments are generally designed for the canines to increase the retention of aligners and minimize the impact of precision cuts.48–50
+## Intermaxillary elastics
+When clear aligners exert a pushing force to achieve molar distalization via material deformation, the counteracting force may procline the anterior teeth. Thus, if anterior tooth proclination is undesirable, the anchorage of the anterior teeth should be reinforced. Intermaxillary elastics are commonly used in practice to achieve this aim.45In maxillary molar distalization, precision cuts are designed at the maxillary canines, whereas buttons are bonded to the buccal surface of the mandibular first molars (cut out on lower aligners) to allow the use of Class II intermaxillary elastics (Fig. 5a).51 If simultaneous eruption of the canine is desirable (e.g., low positioned or insufficiently erupted canines), a button can be bonded to the labial surface of canine near the gingival margin to facilitate eruption (Fig. 5b). However, precision cuts at the mandibular molars are prone to aligner displacement or off-tracking and are not recommended. Additionally, if necessary, implant devices can be used to enhance the anchorage, provided they do not obstruct molar distalization.52–54 On the other hand, if the proclination of anterior teeth is desirable (e.g., Class II Division 2), it can be designed simultaneously with molar distalization, acting as reciprocal anchorage to eliminate the need for any elastics.55 Nevertheless, anterior proclination and molar distalization should be closely monitored during follow-up appointments for real-time adjustments.Fig. 5

+## Considerations for staging
+The staging of tooth movements involves the consideration of anchorage. Typically, molar distalization is designed in a “V-patten” staging, in which the second molars are moved first, and then the first molars once the second molars have reached the halfway point of their total moving distance; thereafter, the second premolars start to move once the second molars have completed their “journey” (Fig. 6a). Thus, no more than four teeth are distalized at each stage (V-pattern).56 Finally, the space created by canine distalization can be used to align and/or retract the anterior teeth. By doing so, the anchorage is often adequate for most distalization cases; however, a long-term treatment is unavoidable.48 In some cases, in order to shorten the treatment duration and increase patient compliance and cooperation, alignment of the anterior teeth is performed simultaneously with molar distalization, allowing patients to observe quick esthetic changes (Fig. 6b). In addition, implant screws can be used to strengthen anchorage, allowing more teeth to distalize simultaneously, to shorten treatment duration (Fig. 6c).57–59Fig. 6

+## Proclination of anterior teeth
+## Indications
+Patients presenting with straight or concave facial profiles and retro-inclined or upright anterior teeth accompanied by mild crowding, such as cases with deep overbite caused by lingual inclination of the upper anterior teeth, are indicated for proclination of anterior teeth, which can be combined with other methods to obtain enough space.
+## Considerations for final position design
+The sagittal position and proclination of the anterior teeth, especially the upper anterior teeth, are crucial for facial esthetics and are one of the main indicators for profile analysis.60–63 Thus, the degree of proclination of the anterior teeth should be carefully evaluated based on facial morphology, and a combination with other methods that help acquire sufficient space should be considered. For patients with a severe lingually inclined deep anterior overbite, the roots-and-bone relationship should be considered. The roots need to be positioned within the cancellous region of the alveolar bone.64,65 Theoretically, a proclination of 1 mm (2.5°) in the anterior segment provides 2 mm of space. Therefore, the proclination design in the final position is based on the amount of space required, facial morphology, and the roots-and-bone relationship.66
+## Attachment design
+More than 3° of incisor proclination activates the power ridge in the designing software system, which applies labial-torquing force on the crowns, whereas lingual-torquing force on the roots and effectively achieves root-controlled movement of the anterior teeth.67 Traditional attachments on canines are recommended to reduce the risk of aligner off-tracking in the anterior segment.
+## Considerations for staging
+A minor proclination can be synchronized with the alignment of mild crowding. However, in cases with lingually inclined deep overbite, staged tooth movement is required. Proclination is first performed to torque the roots into the cancellous bone, and then followed by intrusion and retraction of the anterior teeth.
+## Interproximal reduction (IPR)
+## Indications
+Although IPR is a method for gaining space, it has always been controversial because of the potential damage to the enamel and the resulting risk of caries. The authors suggested that IPR should be used as a supplement to other methods, rather than as the primary method, to gain space. The following situations warrant an IPR design29,31:Bolton discrepancy due to the missing teeth or malformed teeth.Gingival embrasure defects (black triangles) due to periodontal disease.Poor crown morphology with contact points nearby the incisal edge.
+## Considerations for final position design
+In general, IPR is designed in the anterior segment, if needed. It is advisable to limit the maximum amount of IPR to 0.25 mm on the proximal surface of each tooth. Studies have shown that IPR amounting to no more than 50% of the enamel thickness generally does not increase the risk of caries.68–70
+## Considerations for staging
+Since the IPR site is the anatomical contact point of the crown rather than the actual contact point, restoring normal contact points first undoubtedly facilitates IPR performance. However, in practice, there may be situations in which insufficient space hinders the alignment of the dental arch, which requires a comprehensive assessment of the timing of IPR. Graded IPR is recommended to alleviate this contradiction. Fluoride application after IPR performance is suggested.
+## Tooth extraction
+Tooth extraction is a common method for reducing tooth amount in orthodontic treatment and is mainly indicated when the discrepancy between the available and required space exceeds 8 mm, such as in cases with severe crowding or severe maxillary and/or mandibular protrusions. Two types of tooth extraction patterns are commonly used in clear alignment treatment: extraction of lower incisor and extraction of premolars (first or second).
+## Extraction of lower incisors
+## Indications
+An almost normal facial pattern with stable posterior occlusion, no indication for upper extraction, and the total required space in the mandible exceeding 6 mm.Bolton ratio discrepancy due to missing teeth or malformed teeth in maxilla.Poor prognosis of a lower incisor due to periodontal disease or dental trauma.
+Considerations for final position design: The extraction of a lower incisor results in the lack of the midline of the lower dental arch. Instead, the long axis of the lower central incisor may be designed as the lower midline. In most cases, IPR of the upper anterior teeth is necessary to resolve the discrepant Bolton ratio and achieve normal anterior overbite and overjet.71
+Attachment design: it is recommended to design vertical rectangular attachments or root-control attachments on the adjacent teeth to the extraction space, which facilitate the reciprocal movement of the adjacent teeth, especially their roots.72
+Considerations for staging: extracting a lower incisor can effectively relieve crowding in the lower anterior section and provide space for the intrusion of the lower anterior teeth, resulting in a high rate of treatment success. Therefore, special staging considerations are generally not required.
+## Extraction of the first premolars
+Based on the symmetry principle, the extraction of the first 4 premolars is the most common pattern of extraction in orthodontic practice. However, cases needing the extraction of 4 premolars belong to difficult level in CAT (Table 1), and clinicians need to reach a certain level of orthodontic experience to complete the treatment.Indications: Extraction of the first 4 premolars is indicated when the discrepancy between the available and required space exceeds 8 mm, such as cases with severe crowding and/or bimaxillary protrusion, and etc.73Considerations for final position design: most cases with tooth extraction are challenging to treat, as extensive tooth movement is unavoidable, requiring three-dimensional repositioning of these teeth. Treatment success relies on the torque control of the anterior teeth and the mesial-tipping avoidance of the posterior teeth.74–76 Therefore, the final position requires an over-treatment design, as follows:Anterior teeth exhibit a labial inclination with incisor angles of approximately 120°. To prevent excessive lingual inclination, adequate labial inclination and torque control (root-lingual torque) should be designed during the whole procedure of anterior retraction.77 Cases with more lingual inclination at the initial and/or longer retraction distances require a larger positive torque in the design.78Anterior teeth are in a shallow overjet/overbite or edge-to-edge position without occlusal contact. The pendulum effect of anterior retraction, compounded by any pre-existing deep bite condition, may require the over-treatment of anterior intrusion.Canines are mesially tipped with the roots closer to the extraction space.Posterior teeth are distally tipped, with additional negative torque to prevent buccal inclination of molars and loss of posterior anchorage.79Attachment design: In such cases, attachment design should consider the following:Power ridge on incisors is recommended to aid in the torque control of the anterior teeth, which can be activated when more than 3° root-lingual torque is designed.Optimized attachments with strong root control or traditional rectangular attachments are recommended for the canines.74Horizontal rectangular attachments with strong retention are recommended for posterior teeth.Intermaxillary elastics: To increase posterior anchorage, Class II elastics can be designed during anterior retraction (precision cuts at the upper canines and bonding of buttons on the buccal surface of the lower first molars). Alternatively, implant anchorage can be used in the anterior region to assist the intrusion and body retraction of the anterior teeth.80–82 Different modes of elastic tractions with or without mini-implants and their corresponding biomechanics are displayed in Fig. 7.Fig. 7
+Different elastic tractions and biomechanical features. a A class II elastic traction is applied between the precision cut on the upper canine and the button on the lower first molar. Since the traction force (blue dashed line) passes occlusally to the center of resistance (red dot) of the upper anterior teeth, a clockwise moment (blue curved arrow) is generated. b An elastic traction is engaged between the precision cut on the upper canine and a buccal mini-implant. Likewise, a smaller clockwise moment (blue curved arrow) is generated. c One elastic traction is applied between the precision cut on the canine and a buccal mini-implant and the other one is engaged between the aligners on the incisors and a labial mini-implant. The retraction force (blue dashed line) generates a clockwise moment (blue curved arrow) while the intrusion force (yellow dashed line) offers a counterclockwise moment (yellow curved arrow). The two moments are offset by each other and the anterior teeth are retraction in a bodily movement modeConsiderations for staging: a personalized design is suggested for each case. The staging design should vary according to the specific circumstances because of the complex and variable nature of extraction cases. However, in most cases, we recommend distalizing canines and distal tipping of the posterior teeth (anchorage preparation) first. When canines complete the first third of the total moving distance, 6 anterior teeth start to move simultaneously by then. And finally, mesial movement of the posterior teeth begins when anterior teeth movement is completed. To prevent the “bowing effect”, it is suggested to avoid mesial movement of the posterior teeth simultaneously with the retraction of anterior teeth.
+## Extraction of the second premolars
+Indications: In the following cases, second premolars are extracted instead of first premolars, which usually increases the treatment difficulty. Clinicians should be cautious to make a treatment scheme design like this:Serious damage/abnormality on the second premolar and/or its periodontal tissue.Second premolar is impacted or blocked-out of the dental arch.Minimal anchorage design.Considerations for final position design: Compared to those in the first premolar extracted case, molars should be designed with more distal inclination (anchorage preparation) since the molars are more prone to mesial tipping, especially in the cases that more than 3 mm mesial movement of molars is required (minimal anchorage design), while less over-treatment of anterior teeth is needed.Considerations for staging: we suggest, firstly, a sequential distal movement of the first premolars and canines, and distal-tipping anchorage preparation of the first molars. Then, move anterior teeth afterwards. And finally, mesially move the molars sequentially.
+## Bite jump (surgical and growth jump)
+A bite jump refers to the changes in the three-dimensional position of the mandible and/or mandibular dental arch resulting from intermaxillary elastics, self-growth, and/or orthognathic surgery. It is important to note that the design of bite jump should be tailored based on the specific circumstances of the patient, and clinical feasibility should be considered. Except orthognathic surgery, bite jumps caused by other methods develop gradually in clinical practice, which can span the whole course of treatment.Indications:Adolescents with mild skeletal or functional mandibular hypoplasia or retrognathia;83,84Functional Class III, with the mandible being able to retrude to edge-to-edge occlusion;Severe skeletal deformities requiring orthodontic-orthognathic treatment22;Mandibular malposition caused by premature individual tooth contacts.Intermaxillary elastics: The sagittal bite jump requires the use of intermaxillary elastics or orthodontic appliances with mandibular advancement function.85,86Considerations for staging: In the design software, bite jump can be placed at any stage of the treatment or throughout the treatment process. The authors typically place bite jump at the end of the treatment, which makes it easier for clinicians to assess the amount and direction of the jump and detect any abnormalities in a timely manner during clinical monitoring.Below, we are going to delve into some special considerations in clear aligner design. A lot of clinicians are confused by these issues in practice.
+## Special considerations in clear aligner design
+Over-treatment design: as we discussed before, clear aligners exert mainly a “pushing force”, and therefore their clinical efficiency varies among different types of teeth movements (Fig. 1). To better realize the actual teeth movement, over-treatment design is recommended in some cases, which is related to the predictability of CAT. For example, to intrude anterior teeth and correct deep bite, a shallow overbite and even open bite is designed in the final position, while large positive torque may be given to the incisors which are lingual inclined or up-righted initially when retraction of anterior teeth is required to correct the convex profile. However, the appropriate amount of over-treatment design is determined case by case, and until now, there is no consensus on this specific issue. According to our experience and previous clinical studies, the amount of over-treatment should be designed based on the initial status of teeth and the type and amount of the teeth movement.78,79Challenges and strategies in the complex tooth movements: compared to expansion and molar distalization, intrusion, extrusion and torque control are more complex tooth movements in CAT, which have much lower predictability (Fig. 1). Thus, over-treatment is commonly designed for these types of movements.Besides, sufficient space for tooth movements should be taken into considerations. For intrusion, the root-and-bone relationship needs to be analyzed in CBCT images to make sure that the roots are in the cancellous bones, while for extrusion, the intermaxillary space is required. And loose proximal contact points are always good for the movement.Then, sufficient anchorage for the movement is important. There are usually two ways to strengthen anchorage in CAT. One is to move teeth in a stepwise mode. We recommend a “Frog pattern” staging for anterior teeth intrusion, in which incisors and canines are intruded separately and in cycles (Fig. 8). Extrusion of posterior teeth is suggested to be designed in a “V pattern” staging. Besides, power ridge design and positive torque is distributed in the whole procedure of incisor retracting to provide a better torque control. The other way to enhance anchorage is to use auxiliary devices and elastics, such as temporary anchorage devices (TAD) implanted in the anterior section to provide an extra intruding force and root lingual torque on anterior teeth (Fig. 7).Fig. 8
+Staging design for the intrusion of anterior teeth in the lower arch. a Incisors and canines are intruded in an alternate mode. Incisors are intruded first (referred to stage 1), followed by the intrusion of canines (referred to stage 2). Then, incisors are further intruded (referred to stage 3). b Lower arch models showing intrusion of canines and incisors corresponding to the aforementioned three stages. c Anterior and side views showing the successful intrusion of the anterior teethFurthermore, appropriate attachment design could provide clear aligners with greater retention, which is the key for CAT. Traditional attachments on premolars are recommended when intrusion of anterior teeth is needed while traditional attachments on canines are suggested for incisor’s torque control.Differences in the design of CAT between adolescents and adults: as we know, the main difference between adolescents and adults is growth potential which may lead to different orthodontic treatment plan. Mandible growth can result in anteroposterior bite jump, and thus, bite jump design without surgery is more possible to realize in adolescents. Besides, the prevalence of oral caries is higher in adolescents, and therefore, interproximal reduction (IPR) design should be used more cautiously. Moreover, traditional attachments or optimized attachments in larger size are recommended in adolescents due to their inadequate crowns. A recently published expert consensus on adolescents’ orthodontic treatment has deeply discussed this special issue.6
+## Aligner fabrication
+Once aligner treatment planning is ready, clear aligners that move teeth incrementally can be fabricated based on either thermoforming or 3D printing.
+## Fitting of initial set of aligners
+Patients are informed to the clinic for the initial appliance placement when clinicians receive the aligners. On this day, the resin attachments are bonded onto the teeth according to the digital design, and the first set of aligners is tried in (fitness should be checked). Subsequently, patients are issued a set of instructions, including the required wearing duration, method of aligner placement, and usage of chewies. The patients are also informed about the importance of oral hygiene. Additional information and instructions are provided to the patients, as relevant, depending on the tooth movement plan, such as molar distalization, IPR, or extraction.
+## Follow-up monitoring
+## Patient compliance management
+Regular follow-up visits are essential and can be used to inform patients about treatment progress and challenges, helping them understand their roles in the process, increasing their confidence, compliance, and cooperation.18,87Cooperation in the long duration of orthodontic treatment is a huge challenge to majority of people, especially persisting in wearing clear aligners day by day. Thus, close contact with patients helps to know their status and give them a hand or timely reminding if needed. Pleasure communication and compliments on patients are always effective in maintaining good relationship between clinicians and patients, which is beneficial for the cooperation as well. To encourage patients, practitioners can show them the changes already occurred by comparing with their pre-treatment photos and inform them that all these changes are owing to their compliance and cooperation. Let patients be aware of that their efforts will pay back. By doing so, patients will be more confident in the treatment.Besides, some application programs registered by patients’ ID number can be used on smart cell phone to help record the wearing date and remind to change a new set, which is convenient for patients in daily life.
+## Things to do in the follow-up visits
+To evaluate treatment progress, comprehensive examinations should be performed, including the following assessment:Tooth and periodontium status assessment, including mobility, premature contact presence, and occlusal trauma.88,89Occlusion changes, including the sagittal relationship, occlusal contacts, inclination, midline of upper/lower dental arch, overjet, overbite, torque and space, comparing to baseline and digital design.Temporomandibular joint health assessment should interrogate any pain, tenderness, and clicking in the joint area, especially in patients with temporomandibular disease before treatment and in adult patients using intermaxillary elastics.90–93Any detachment and/or abrasion of attachments should be checked according to digital design.94Aligner fitness assessments account for the progress in tooth movement, especially any gap observed in the space from the incisal edges of the anterior teeth, cusps of the posterior teeth, and the area around the attachments and along the aligner margin.
+## Management of off-tracking
+Off-tracking refers to the incomplete fitting between the teeth and aligners, indicative of a discrepancy between the direction and/or distance of actual tooth movement and that planned in the digital design (Fig. 9). The management of off-tracking involves removing attachments and using aligners to guide the off-tracking teeth back into the desired path using intra-/inter-maxillary elastics. Off-tracking manifestations can be categorized into the following three situations:Off-tracking in the vertical dimension due to insufficient extrusion or anterior intrusion.95 Insufficient extrusion may manifest as uniform vacuoles emerging at the incisal edges or cusps and can be managed by removing the attachments on the off-tracking teeth and applying intra-/inter-maxillary elastics (Fig. 10a). Alternatively, in cases of insufficient anterior intrusion, which manifest as inadequate correction of the anterior deep bite, auxiliary devices, such as implants or redesigning additional aligners to increase the staging design for tooth movement, may be added.Off-tracking in the horizontal dimension commonly occurs in rotation correction, especially in severely rotated premolars.96 The removal of attachments and use of a power chain can be helpful in most cases (Fig. 10b).Off-tracking in the sagittal dimension is characterized by mesial inclination of the posterior teeth and torque loss of the anterior teeth (lingual inclination).75,76 Mismatches between the attachments and vacuoles on the aligners can be observed on mesially inclined posterior teeth, as well as the gaps between the mesial cups and aligners. Distal up-righting of these off-tracking teeth must be performed using intermaxillary elastics and/or sectional arch wires after the removal of the attachments (Fig. 10c, d).The loss of anterior tooth torque manifests as lingual inclination of the upper/lower anterior teeth, increased overbite, early contact of anterior teeth, and posterior open bite.97 In such cases, the aligners may need to be redesigned to restart the program.Fig. 9

+Strategies for resolution of tooth off-tracking. a A “boot-strapping” technique was used to address the off-tracking of a lateral incisor by applying labial-lingual elastic traction. b A power chain was used to correct under-derotation of a second premolar. c A vertical elastic traction from the upper premolar to the lower molar was implemented to correct mesial tipping and intrusion of the lower first molar. d A segmental archwire technique was applied to correct mesial tipping of a lower second molar
+## Timing and considerations of program restart
+Sometimes not only one series of clear aligners are needed to complete the treatment. There are five possible reasons for this:The discrepancy between designed tooth movement and actual tooth movement, which result in an incomplete correction of the malocclusion, often occurring in some complex tooth movement, like intrusion, root control and more than 3 mm molar distalization. More series of aligners are designed to accomplish the treatment goal.Unwanted tooth movement occurs and leads to reduced occlusal contacts or even open bite in posterior segment, which may be due to the aligners’ effect of occlusal pad. More series of aligners are designed to consolidate the occlusion.More teeth should be included into treatment, which is common in adolescents with erupting second molars. A new series of aligners are usually designed to cover these second molars and some heterotopic or impacted teeth, if any.The change of occlusal relationship may occur, due to mandible growth and/or removal of occlusal interference. Then, a completely new design should be done according to the new and stable occlusal relationship.Bad cooperation in patients, leads to serious off-tracking, and even totally unfitting. A new series of aligners are designed based on current status.
+## Treatment outcome
+Treatment is complete after waring the final set of aligners, if the treatment objective has been achieved. The criteria for ending CAT are consistent with those for ending traditional fixed orthodontic treatment. At the end of the treatment, the attachments and other auxiliary devices are removed, and retainers are prescribed as usual.
+## Retention
+Retention is of vital importance to clear aligner treatment. Different modalities of retention can be chosen based on patient-specific characteristics, e.g., periodontal condition, caries vulnerability, etc. Patients should be recalled to check tooth alignment, retainer fitting, and signs of relapse.
+## Complications
+CAT is associated with some risks to dental and periodontal health.
+## Caries
+Poor oral hygiene during CAT can disrupt the oral microbiota, leading to white spot lesions or even caries.98 However, compared to patients undergoing fixed orthodontic treatment, patients wearing clear aligners have lower levels of white spot lesions, total bacterial plaque, and cariogenic bacteria in the saliva.99–101 This may be related to the reduced detrimental effect of clear aligners on oral hygiene.
+## Root resorption
+CAT may lead to root resorption. However, it reported that CAT applied a gentler force, resulting in a lower rate and severity of root resorption, compared to those observed in fixed orthodontic treatment.102–105 Factors such as post-treatment root position (relationship with the cortical bone), extraction, tooth position, and specific tooth movement patterns (intrusion and extrusion) are all risk factors for root resorption, whereas post-treatment root position is most closely related to root resorption.106 Therefore, reducing the risk of root resorption requires limiting root movement within cancellous bone and avoiding unnecessary reciprocal movement. Furthermore, a clear aligner design software with a root-bone system makes the root-bone relationship visible in the digital design, which helps reduce root resorption risks.
+## Periodontal damage
+Standard orthodontic treatments do not cause periodontal damage. However, orthodontic appliances may increase the difficulty of maintaining oral hygiene, leading to a higher rate of gingivitis and periodontitis. Clinical trials have shown that, compared to fixed orthodontic appliances, clear aligners are more favorable for maintaining periodontal health in patients.107–110 Moreover, for cases with an unsatisfactory periodontal status, design changes can help mitigate these risks by decreasing the speed of tooth movement, reducing teeth coverage by aligners, and prolonging the wearing duration for each set of aligners. Thus, clear aligners are recommended for patients susceptible to gingivitis and/or periodontitis.Meanwhile, alveolar bone defect (fenestration and dehiscence) is also a common complication of orthodontic treatment. A recent study found that the incidence of fenestration in patients treated with clear aligner and fixed appliance was 23.96% and 26.18%, respectively.111 Another investigation also showed that non-extraction CAT was associated with increased presence of alveolar bone dehiscence and fenestration.112 Thus, root-bone relationship should be considered and evaluated carefully, especially arch expansion is designed.
+## Relapse
+After orthodontic treatment, relapse tends to occur because of incomplete remodeling of the periodontal tissues and muscular system. In the literature, relapse has been mainly linked to occlusal stability, types of tooth movement, root-bone relationships, and the balance of intraoral and extraoral muscle forces, with the type of orthodontic appliance used having minimal impact on relapse risk.113–115 The use of retainers and correction of oral bad habits (such as tongue-thrust swallowing, etc.) are currently considered the most effective measures for reducing relapse risk.
+## Conclusion and expectation
+The design of clear aligners continues to evolve, taking advantage of the novel materials and insights generated by global big data studies, leading to less difficulty in complex cases treatment, allowing more patients worldwide to achieve better treatment outcome by this technology. A novel clear aligner philosophy—biomechanics-guided, esthetics-driven, periodontium-supported and TMJ-compatible clear aligner therapy (BEPT-CAT)—may be applied in clinical practice to guide aligner treatment planning and execution. Moreover, the possibility of tiny attachments or attachment-free designs may become feasible, further improve patients’ comfort and esthetics during treatment. In the future, individual dental practices may be equipped with devices that allow to 3D-print the elements of the novel designs, further increasing treatment personalization.Advances in science and technology are driving progress in orthodontics. Esthetic, comfortable, convenient, and efficient orthodontic treatment will be realized through digitally oriented invisible aligner technology, bringing CAT into mainstream use.

+# 이미지 소스 후보 조사 (2026-05-15)
+
+현재 9개 소스로 4809 term 중 329개(6.8%) 매핑. 0% 카테고리는 치과마취학·치과
+생체재료학. 추가 소스 6개를 조사·실측한 결과를 정리한다.
+
+## 비교 요약
+
+| 후보 | 통합 비용 | 예상 수율 | 라이선스 안전 | 0% 카테고리 도움 | 종합 |
+|---|---|---|---|---|---|
+| NLM Open-i | 낮음 | **높음** | 높음 (PMC OA) | 부분 | **★★★★★** |
+| Tufts Dental | 낮음 (1회 요청) | 중 | 높음 (CC-BY) | 영상의학만 | **★★★★** |
+| Wellcome Collection | 낮음 | 낮음 | 중 (per-image) | 해부만 | ★★★ |
+| Kaggle 타깃 | 낮음 | 중 | 데이터셋별 | 보철 X선만 | ★★★ |
+| figshare | 중 | **불확실** | 필터 가능 | 불확실 | ★★ |
+| NCBI Bookshelf | 중-높음 | 중 | **NC-ND 다수** | 마취 일부 | ★★ |
+
+## 1. NLM Open-i — **1순위**
+
+- **엔드포인트**: `https://openi.nlm.nih.gov/api/search?query=<term>&m=<start>&n=<count>` (인증 불필요)
+- **규모**: 370만 이미지 / 120만 PMC 기사 + 7,400 흉부 X선 + NLM History 67,500 + MedPix
+- **실측 수율**: "periodontitis" 검색 → **7,588 hits**. 한 query당 결과 풍부.
+- **응답 필드**: `uid, pmcid, pmid, title, journal_title, authors, MeSH terms (major/minor), Outcome 점수, image URL`
+- **이미지 URL 패턴**: `https://openi.nlm.nih.gov/imgs/{100|137|150|512}/{id}/{pmcid}/PMC{pmcid}_{imgid}.png`
+- **라이선스**: PMC Open Access 기반 (CC-BY/CC0 등), 출처 표기로 재사용 가능
+- **현 `map_pmc_oa` 대비 우위**:
+  - **Figure-level 색인** (현재는 article HTML 스크레이프해서 그림 추출 → 노이즈 많음)
+  - **MeSH terms 포함** → 한글 용어 매핑에 도움 (영문 → MeSH 매칭 후 검색)
+  - **유사 이미지 검색** (`similarInCollection`)
+  - PMC와 같은 풀이지만 색인 품질 우수
+- **통합 비용**: `workflow_images.py`에 `map_openi(conn, max_terms, delay)` 함수 1개 추가. 기존 `verify_updates` 게이트 그대로 통과 가능. **약 2시간 작업**.
+
+## 2. Tufts Dental Database — **2순위**
+
+- **URL**: https://tdd.ece.tufts.edu/
+- **규모**: 파노라마 X선 **1,000장**, 전문가의 abnormality 레이블 + 치아 번호 주석 (multimodal)
+- **라이선스**: **Creative Commons Attribution 4.0** — 재배포·재사용 OK
+- **접근**: 웹사이트에서 **접근 요청 폼** 작성 (즉시 다운로드 X)
+- **적합 카테고리**: 구강악안면영상의학 (현재 13.9%, 추가 보강 가능). 주석이 있어 단순 X선보다 매핑 가치 큼.
+- **통합 비용**: 다운로드 후 로컬 매핑 (기존 kaggle 패턴 동일). **30분 + 접근 승인 대기**.
+- **주의**: 이미 영상의학은 비교적 잘 채워진 편 → ROI는 Open-i보다 낮음.
+
+## 3. Wellcome Collection — **4순위**
+
+- **엔드포인트**: `https://api.wellcomecollection.org/catalogue/v2/images?query=<term>&pageSize=N` (인증 불필요)
+- **실측 수율**: "periodontitis" → **단 7개**. 임상 용어엔 낮음.
+- **응답**: IIIF URL, 작품 metadata, 이미지별 라이선스 (CC BY 4.0 / "In copyright" 혼재)
+- **이미지 URL**: `https://iiif.wellcomecollection.org/image/{id}/info.json` (IIIF Image API)
+- **라이선스**: per-image — 필터링 로직 필요
+- **적합 카테고리**: 해부·역사적 일러스트 (기초치의학 일부) — 임상·방사선엔 부적합
+- **통합 비용**: 낮음, 하지만 **수율 대비 가치 낮음**
+
+## 4. Kaggle 추가 타깃 데이터셋
+
+검색 결과 (보철·임플란트 관련):
+- **Dental Implant Dataset (Mendeley `x4gr6mmwy4`)**: 5,273 파노라마 X선, Endosteal/Transosteal/Subperiosteal/Zygomatic 4종 분류
+- **Prosthesis detection 데이터셋** (Nature Sci Rep 2021): 2,235 파노라마, 크라운/브릿지/임플란트
+- 기타: Dental Cavity Detection, Panoramic Dental Xray TFRecords
+
+**한계**: 대부분 **파노라마 X선**, 직접적인 크라운·틀니 임상 사진은 드묾. 보철(1.0%) 카테고리의 임상 사진 수요엔 부분적 해결.
+
+- **통합 비용**: 다운로드 + 기존 kaggle 패턴 적용 (각 1-2시간)
+- **라이선스**: 데이터셋별 확인 필요
+
+## 5. figshare API — 보류
+
+- **엔드포인트**: `https://api.figshare.com/v2/articles?search_for=<term>` (인증 불필요)
+- **라이선스 필터**: `:licence:CCBY` 지원
+- **레이트 리미트**: ≤1 req/s 권장
+- **실측 결과**: "dental caries" 검색 → **무관한 결과 다수** (수질, 호텔 추천, 게놈 등). 검색 색인 품질이 의심스러움.
+- **결론**: 통합 전에 **검색 query 형식·필터링 추가 조사 필요**. 현 단계에선 우선순위 낮음.
+
+## 6. NCBI Bookshelf — 보류
+
+- **접근**: `https://www.ncbi.nlm.nih.gov/books/` + LitArch FTP for bulk
+- **콘텐츠**: StatPearls(2026), 치과마취·구강외과 chapter들 다수
+- **라이선스**: **CC-BY-NC-ND가 다수** — Non-Commercial + No-Derivatives → DB에 그림 URL 임베드 가능하나 변형/상업적 재사용 금지. SmallClaw 용도에 따라 적합 여부 갈림.
+- **적합 카테고리**: 치과마취학(0%) 추상 개념 (작용 기전 도식 등)
+- **통합 비용**: Bookshelf XML 파싱·그림 추출 로직 필요 (PMC와 다른 포맷)
+- **결론**: NC-ND 비율 확인 + 라이선스 정책 결정 후 진행
+
+## 핵심 인사이트
+
+1. **0% 카테고리(치과마취학·치과생체재료학) 매핑은 본질적으로 어려움**
+   - "전도마취", "법랑질-상아질 접합부 미세구조" 같은 추상·미시 개념
+   - 이미지로 직접 표현 가능한 비율이 낮음 — 어떤 소스로도 한계 존재
+   - **현실적 목표**: 0% → 10~20% 정도
+
+2. **수율은 Open-i > Kaggle > Wellcome 순**
+   - Open-i 하나로 수백 term 추가 매핑 기대 (수율 추정 30-50%)
+   - 나머지는 보조 역할
+
+3. **검증 게이트(qwen3.5)가 노이즈를 잡아주므로** 양 우선 소스 추가 후 verify로 거르는 전략이 효율적
+
+## 추천 진행 순서
+
+1. **Open-i 통합** (2시간) — 즉시 착수 가능, ROI 최대
+2. **`add-images --source openi --max-openi 500` 후 `verify --fix`** — 결과 평가
+3. **Tufts Dental 접근 요청** — 영상의학 보강용, 승인 대기 동안 1단계 진행
+4. **Kaggle 보철·임플란트 데이터셋 평가** — 다운로드 후 효용 확인
+5. **Wellcome Collection** — 시간 여유 있으면 추가
+6. **figshare / Bookshelf** — 별도 라이선스·검색 품질 조사 후 결정

+1. [Wokwi](https://wokwi.com) 에 접속
+2. 새 ESP32 프로젝트 생성
+3. `wokwi/diagram.json` 내용을 복사
+4. `src/` 폴더의 파일들을 업로드
+5. `sketch.ino` 에 `main.cpp` 내용 복사
+6. 시뮬레이션 실행
+
+### Wokwi에서 토양 습도 시뮬레이션
+- 가변저항(Potentiometer)으로 토양 습도 시뮬레이션
+- 왼쪽으로 돌리면 건조, 오른쪽으로 돌리면 습함
+
+## 🌐 대시보드 접속
+
+1. ESP32가 WiFi에 연결되면 시리얼 모니터에 IP 주소 표시
+2. 브라우저에서 `http://<ESP32_IP>` 접속
+3. 실시간 센서 데이터 확인 및 원격 제어 가능
+
+### 대시보드 기능
+- 🌡️ 실시간 온도 표시 (게이지)
+- 💧 실시간 습도 표시
+- 🌱 토양 습도 표시
+- 🚿 펌프 수동/자동 제어
+- 🌀 팬 수동 제어
+- ⚠️ 경보 상태 표시 (주의/위험)
+- 📊 데이터 로깅 (최대 288포인트)
+
+## ⚙️ 임계값 설정
+
+`config.h`에서 환경에 맞게 조정:
+
+```cpp
+#define SOIL_DRY    25.0   // 토양이 건조하다고 판단하는 습도 %
+#define SOIL_MOIST  60.0   // 적정 습도 %
+#define SOIL_WET    80.0   // 과습 습도 %
+#define TEMP_HIGH_WARNING 30.0  // 고온 주의 °C
+```
+
+## 📡 API 엔드포인트
+
+| 엔드포인트 | 메서드 | 설명 |
+|-----------|--------|------|
+| `/` | GET | 대시보드 HTML |
+| `/api/data` | GET | 현재 센서 데이터 JSON |
+| `/api/history` | GET | 로깅된 데이터 JSON |
+| `/api/control?pump=1` | POST | 펌프 켜기 |
+| `/api/control?fan=1` | POST | 팬 켜기 |
+| `/api/control?auto=1` | POST | 자동물주기 토글 |
+
+## 🔌 ESP32-CAM 연결 (선택)

+### **매복된 제1대구치와 안면 및 골격 발달과의 연관성**
+
+**Zehava Geller Fishman,**a **Avi Leibovich,**a **Heli Rushinek,**b **Roberta Lione,**c **Paola Cozza,**c **Adrian Becker,**a **Stella Chaushu**
+예루살렘, 이스라엘 및 로마, 이탈리아
+
+#### **서론**
+매복된 영구 대구치(infraocclusion)는 일반적으로 **유착(ankylosis)**에 의해 발생하지만, 이에 대한 연구는 아직 부족한 실정이다. **일측성 제1대구치 매복(Unilateral First Molar Infraocclusion, UFMI)**은 국소적인 치조골 발육을 저해하여 비대칭적인 치아궁과 교합을 유발한다. 본 연구는 이러한 영향이 치아 구조를 넘어 **안면 및 골격 비대칭**으로까지 확장되는지를 조사하였다.
+
+**방법:**
+UFMI를 가진 연속적으로 모집된 환자들을 연령 및 성별이 일치하는 대조군과 비교하는 **후향적 분석**을 실시하였다. 교합평면 경사(occlusal cant, OC), 턱끝 편위(chin deviation, CD), 평균 수직 비대칭 지수(vertical asymmetry index, VAI), 하악지 길이 차이 비율(ramus length difference ratio, RLD) 및 관절돌기 길이 차이 비율을 평가하였다. 임상적 유의성을 위해 VAI와 RLD 값이 **0.3% 이상**인 환자의 비율을 비교하였으며, 연령 및 악궁(상악/하악)의 영향을 분석하였다.
+
+**결과:**
+UFMI 그룹은 29명의 환자(남자 16명, 여자 13명, 평균 연령 13.4 ± 3.8세)로 구성되었다. UFMI 환자는 대조군에 비해 유의하게 더 많은 **CD(59.0% vs 14.0%)**와 **OC(38.0% vs 7.0%)**, 그리고 더 높은 **VAI(3.2% vs 1.0%)**와 **RLD 비율(4.0% vs 2.0%)**을 보였다. VAI가 0.3%를 초과한 경우는 UFMI 환자의 **34.5%**에서 관찰되었으며, 대조군에서는 한 명도 없었다(P<0.001). RLD 비율이 0.3%를 초과한 경우는 UFMI 환자의 **51.7%**에서, 대조군의 **24%**에서 관찰되었다(P = 0.030). UFMI 그룹에서 **CD와 OC의 유병률**은 연령이 증가할수록 유의하게 증가하였으며, **상악 UFMI**가 하악보다 더 큰 영향을 미치는 것으로 나타났다.
+
+**결론:**
+UFMI는 **안면 및 골격 비대칭**과 유의한 연관성이 있으며, 특히 **고연령 집단**에서 그 영향이 더 크다. 이러한 결과는 **조기 진단 및 개입**을 통해 안면 성장 및 발달에 미치는 장기적인 영향을 완화할 수 있는 잠재적 중요성을 강조한다.

+
+#### **본문**
+
+##### **영구 제1대구치 매복의 정의 및 원인**
+영구 제1대구치의 **매복(infraocclusion)**은 치아 맹출의 정지로 인해 발생한다.1 이는 맹출 경로상의 **물리적 장애물**, 치아 외상, 감염 또는 유전적 요인에 의해 유발될 수 있으나, **유착(ankylosis)**이 그 병인에서 핵심적인 역할을 한다.1
+
+**유착(ankylosis)**은 치아가 주변 골과 **융합**되어 움직이지 않게 되는 상태로,2 정상적으로 치아를 골에 부착시키는 **치주인대**가 골 조직으로 대체되면서 치아와 골 사이에 직접적인 연결이 형성된다. 이로 인해 정상적인 치아 맹출과 교합 발육이 저해되며,3 그 결과 **매복(infraocclusion)** 또는 **침하(submergence)**가 발생한다. 이때 해당 치아는 주변 치아보다 낮은 위치에 자리하게 된다.4-6
+
+##### **유착의 발생 및 유병률**
+유착은 **유치열과 영구치열** 모두에서 발생할 수 있으며, **하악**에서 상악보다 **두 배** 더 흔하게 나타난다.2 가장 흔히 영향을 받는 치아는 **유구치**로, 연구자에 따라 정의가 다름에 따라 유병률은 **1%에서 30%**까지 다양하다.7,8 영구치열에서의 유병률에 대한 자료는 부족하지만, 유치열보다 약 **10배 낮을 것**으로 추정되며, 가장 흔히 영향을 받는 치아는 **영구 대구치**이다.2,3,9
+
+##### **유착의 원인**
+유착의 원인은 아직 완전히 밝혀지지 않았지만, 여러 이론과 기전이 제시되어 왔다.2,3,9-11 이는 다음과 같다:
+- 국소적인 **골 및 치주인대 대사 장애**
+- **맹출력 저하**
+- **국소 감염**
+- 화학적 또는 열적 손상
+- **국소 외상**
+- 부적절한 **혀 압력**
+
+또한 **명확한 유전적 영향**도 보고되었으며,8,10,12,13 유착의 원인은 **내인성 및 외인성 요인**을 모두 포함하는 다양성을 지닌다.
+
+##### **진단 방법**
+진단은 **임상 검사**와 **방사선 영상**을 통해 이루어진다.1,14-16 임상적으로 유착된 치아는 일반적으로 **매복**되어 있으며, **타진 시 둔탁한 소리**를 낸다. 그러나 **확진**은 해당 치아를 발치한 후 **조직학적 검사**를 통해서만 가능하다.14 따라서 조직학적으로 증명되지 않는 한, 이러한 치아에 대한 가장 적절한 임상 용어는 **매복(infraocclusion)**이다.
+
+##### **매복 대구치의 영향**
+대구치 매복은 **국소적인 부정교합**을 유발할 수 있으며, 인접 치아가 영향을 받은 치아 쪽으로 **기울어질 수 있다**.3,4,17 이는 동일한 치아궁 내 다른 치아에도 영향을 미쳐, **정중선이 영향을 받은 치아 쪽으로 편위**되고, 인접한 원심 대구치는 더 원심位に 위치하게 된다.6 또한 **반대측 치아궁**도 영향을 받을 수 있는데, 이는 상대 치아가 **과맹출**되는 경향이 있기 때문이다.5
+
+더 넓은 영향으로는 **치조골의 발육 부전**으로 인해 골 높이가 감소하고, **교합평면이 영향을 받은 측으로 경사**지게 된다.3,9,18-20
+
+##### **유치 vs 영구치 유착의 차이**
+유착된 **유치**와 **영구치**의 영향은 크게 다르다. 대부분의 매복된 유구치는 영구치가 맹출하는 동안 **정상적으로 탈락**하며, 골 수준도 정상화된다.21,22 반면, **영구 대구치**가 성장 중에 유착되면 **뚜렷한 수직적 결손**이 발생할 수 있다.18 결손의 정도는 환자의 **잔여 성장량**에 따라 달라지며,19 유착이 치아 맹출 초기에 발생하고 환자에게 예상되는 성장이 남아 있을 경우, 그 영향은 더 심해지고 **예후는 악화**된다. 이는 영향을 받은 치아가 인접한 맹출 치아에 비해 상대적으로 더 침하되고, 잔여 성장 기간 동안 **골 수준의 불일치가 빠르게 증가**하기 때문이다.11,18
+
+##### **안면 및 골격 성장과의 연관성**
+문헌에서는 명시적으로 언급되지 않았지만, **심한 일측성 유착 및 매복**으로 인한 비대칭적인 치조골 발육 장애가 **안면 및 골격 성장**에도 영향을 미칠 수 있을 것으로 추정된다. 따라서 본 연구의 목적은 **일측성 영구 제1대구치 매복(UFMI)**이 골격 또는 안면 비대칭과 연관성이 있는지를 조사하는 것이다.
+
+#### **재료 및 방법**
+본 연구는 예루살렘 히브리대학교 하다사 치의학대학 교정과에서 **연속적으로 모집된 UFMI 환자**의 치료 전 기록을 대상으로 한 **후향적 분석**이다. 이 연구는 하다사 의료기관 연구윤리위원회의 승인을 받았다(HMO-0131-22).

+
+##### **측정 방법**
+모든 측정은 저자 중 한 명(Z.G.F.)이 수행하였으며, 무작위로 선택된 8명의 환자에 대해 **2주 이상의 간격**을 두고 두 번 평가하였고, 다른 검사자(A.L.)가 재평가를 실시하였다. **재현성 및 정확성**을 평가하기 위해 **급내상관계수(intraclass correlation coefficients)**를 사용하였다.

+   - (3) **수직 비대칭 지수(VAI):** 오른쪽과 왼쪽 연조직 하악각(soft-tissue gonial angle)의 수직 길이를 비교하여 계산
+     **VAI (%) = ([오른쪽 수직 하악각 길이 - 왼쪽 수직 하악각 길이] / [오른쪽과 왼쪽 길이의 평균]) × 100**
+
+2. **파노라마 방사선 검사(Fig 1, B):**

+- **악궁 영향 분석:** 상악 UFMI와 하악 UFMI 환자 간의 비대칭 비교
+
+##### **통계 분석**
+- **연속 변수 비교:** Wilcoxon 부호순위 검정(대응 표본), Mann-Whitney 검정(비대응 표본)
+- **이분형 변수 분석:** 카이제곱 검정
+- **상관성 분석:** Spearman 상관계수, 점-이연 상관(point-biserial correlation)
+- **유의수준:** P < 0.05
+
+#### **결과**

+
+13세 미만 UFMI군에서 **턱 편위(CD)** 유병률이 연령대별 대조군보다 높았습니다(각각 54% vs 21%, P = 0.04, 표 3). 마찬가지로 13세 이상 UFMI군에서도 대조군에 비해 **CD** 유병률이 유의하게 높았습니다(각각 63% vs 7%, P = 0.001, 표 3). 대조군에서는 연령이 증가할수록 **CD** 유병률이 감소한 반면(13세 미만 21%, 13세 이상 7%), UFMI군에서는 유의하게 증가했습니다(54%에서 63%, P = 0.006, 그림 2).
+
+**교합평면 경사(OC)** 유병률은 13세 미만 UFMI군에서 8%, 대조군에서 14%로 통계적으로 유의한 차이는 없었습니다. 그러나 13세 이상 그룹에서는 UFMI군의 62.5%가 **OC**를 보인 반면, 대조군에서는 0%로 유의한 차이가 관찰되었습니다(P = 0.0002). 대조군에서는 연령에 따른 **OC** 유병률 차이가 없었으나, UFMI군에서는 13세 미만 그룹의 8%에 비해 13세 이상 그룹에서 62.5%로 유의한 차이가 있었습니다(P = 0.006, 그림 2B).
+
+**수직 비대칭 지수(VAI)**는 모든 연령대에서 UFMI군이 대조군보다 유의하게 높았습니다(표 3). 13세 미만 UFMI군에서는 대조군보다 **VAI**가 2% 높았으며(각각 3% vs 1%, P < 0.001), 13세 이상 그룹에서도 UFMI군이 대조군보다 2.5% 높았습니다(각각 3.5% vs 1%, P = 0.029). 반면 **하악지 길이 차이 비율(RLD)**는 13세 미만 그룹에서만 유의한 차이가 관찰되었습니다(각각 4% vs 1%, P = 0.004, 표 3).
+
+### **상악과 하악 저교합 치아 비교**
+
+| 변수 | 상악, % | 하악, % | P 값 |

+| **OC** | 33 | 41 | 0.660 |
+| **CD** | 66 | 53 | 0.450 |

+| **RLD** | 5.16 ± 5.58 | 3.63 ± 3.26 | 0.580 |
+| **CLD** | 7.49 ± 4.37 | 4.97 ± 3.64 | 0.043* |
+
+**VAI, RLD, CLD**는 하악보다 상악에서 더 높은 값을 보였으나, **관절 길이 차이 비율(CLD)**만 통계적으로 유의한 차이를 보였습니다(각각 7% vs 5%, P = 0.04, 표 4). **OC**와 **CD** 유병률에서는 유의한 차이가 없었습니다(표 4).
+
+### **임상적 유의성 기준(3%) 비교**
+
+임상적 유의성을 평가하기 위해 **VAI**와 **RLD** 측정값에 대해 3%의 임계값을 설정했습니다(Habets et al26 및 Nicot et al25 참조). Habets et al26은 파노라마 영상 촬영 시 머리 위치 1cm 변화가 좌우 관절 크기 측정값에서 최대 6% 차이를 유발할 수 있으며, 이는 비대칭 지수로 환산 시 3%에 해당한다고 보고했습니다. 따라서 3% 이하의 비대칭 값은 영상 촬영 시 기술적 오류로 간주될 수 있으며, 본 연구에서는 이 임계값을 기준으로 결과를 분석했습니다(표 5).
+
+| 변수 | 대조군, % | UFMI군, % | P 값 |
+|------|----------|----------|------|
+| **전체** |  |  |  |
+| - VAI ≥ 3% | 0 | 34.5 | <0.001* |
+| - RLD ≥ 3% | 24.0 | 51.7 | 0.030* |
+| **13세 이상** |  |  |  |
+| - VAI ≥ 3% | 0 | 25.0 | 0.038* |
+| - RLD ≥ 3% | 40.0 | 56.0 | 0.290 |
+| **13세 미만** |  |  |  |
+| - VAI ≥ 3% | 0 | 46.0 | 0.003* |
+| - RLD ≥ 3% | 7.0 | 46.0 | 0.016* |
+
+대조군에서는 **VAI**가 3%를 초과한 경우가 없었으나, UFMI군의 35%는 **VAI**가 3%를 초과했습니다(P < 0.001, 표 5). 연령별 하위 그룹에서도 유의한 차이가 관찰되었습니다(표 5).
+
+**RLD**의 경우, 대조군에서도 3%를 초과하는 경우가 있었으나, UFMI군에서 **RLD**가 3%를 초과한 비율이 유의하게 높았습니다(각각 52% vs 24%, P = 0.030, 표 5). 흥미롭게도 대조군에서는 연령이 증가할수록 **RLD ≥ 3%**의 비율이 증가한 반면(그림 3A), UFMI군에서는 연령별 차이가 유의하지 않았습니다(그림 3B). 그 결과, UFMI군과 대조군 간의 유의한 차이는 13세 미만 그룹에서만 관찰되었습니다(각각 46% vs 7%, P = 0.016, 표 5).
+
+### **초기 분석: 연령에 관계없는 전체 그룹 비교 (그림 4)**
+
+대조군에서는 **VAI**와 **RLD** 간에 중간 정도의 유의미한 양의 상관관계(0.42, P = 0.024, 그림 4A)가 관찰되었으며, **RLD**와 연령 간에도 유의미한 양의 상관관계(0.48, P = 0.008, 그림 4A)가 있었습니다. 그러나 **OC** 또는 **CD**와 다른 변수들 간의 유의미한 상관관계는 발견되지 않았습니다(그림 4A).
+
+반면 UFMI군에서는 **OC** 유병률과 연령 간(0.43, P = 0.019), 그리고 **OC**와 **CD** 간(0.51, P = 0.004)에 유의미한 중간 정도의 양의 상관관계가 관찰되었습니다(그림 4B). 또한 **CD**와 **RLD** 간에도 유의미한 양의 상관관계(0.38, P = 0.039)가 있었습니다(그림 4B).
+
+### **연령이 상관관계에 미치는 영향**
+
+13세 이상 그룹에서는 대조군에서 **RLD**와 **VAI** 간에 유의미한 중간 정도의 양의 상관관계(0.62, P = 0.015, 그림 4C)가 관찰되었으며, UFMI군에서는 **CD**와 **OC** 간(0.73, P = 0.008, 그림 4D), 그리고 **VAI**와 **RLD** 간(0.53, P = 0.037, 그림 4D)에 유의미한 양의 상관관계가 있었습니다. 반면, 13세 미만 그룹에서는 대조군과 UFMI군 모두에서 연령과 관련된 유의미한 상관관계는 발견되지 않았습니다(그림 4E, F).
+
+### **고찰**
+
+본 연구는 일측성 영구 제1대구치 저교합(UFMI)으로 인해 맹출되지 않은 비교적 많은 수의 환자를 대상으로 진행되었습니다. 이는 아마도 치아 유합(ankylosis)에 기인한 것으로 보입니다. 표본 분포는 하악에 더 많은 경우가 관찰되었으며, 이는 저교합 유구치의 분포와 유사합니다.7,27 또한 좌측 편중 현상이 관찰되었으며, 이는 치아 전위,28,29 매복 구개견치,30 상악 측절치 결손,31 원추형 상악 측절치,32 구순구개열 및 측방 안면 열과 같은 다른 치아 이상에서도 보고된 바 있습니다.33
+
+연구 결과는 정상적으로 맹출된 대구치를 가진 연령 및 성별이 일치하는 대조군과 비교했을 때, UFMI 환자에서 안면 및 골격 비대칭의 유병률이 유의미하게 증가했음을 명확히 보여줍니다. 또한 이러한 비대칭은 연령이 증가할수록 더욱 심해졌습니다(그림 5). 우리가 아는 한, 대구치 저교합이 안면 및 골격 발육에 미치는 이러한 광범위한 영향은 지금까지 보고된 적이 없습니다.
+
+이러한 현상에 대한 가능한 설명은 치아 맹출이 안면 발육에 미치는 영향을 이해하는 데 있습니다. 성장 중인 개체에서 대구치가 맹출되지 않고 저교합 상태로 남아 있으면 주변 골격의 발육과 정상적인 수직 골격 성장이 저해됩니다.5,20 유구치 저교합과 하악 성장 간의 상관관계는 Leonardi et al34과 Lanteri et al35에 의해 이전에 보고된 바 있습니다. 그러나 이러한 상관관계가 사실이라 하더라도, 유구치가 탈락하고 후속 영구치가 맹출되면 그 영향은 일시적이며 해결됩니다.21,22 반면, 영구치에서 일측성 대구치 저교합이 발생하면 턱의 양측 발육 불균형과 영구적인 비대칭을 초래할 수 있습니다. 저교합된 대구치와 주변 발육 부진한 치조골에 적응하기 위해 턱이 이동하면서 불균형한 교합에 적응하기 위한 보상 변화가 발생하고, 이는 결국 근육에도 영향을 미치게 됩니다.
+
+UFMI군에서 **VAI(수직 비대칭 지수)** 값이 대조군보다 유의미하게 높았습니다(표 2). 이러한 경향은 두 연령 하위 그룹에서도 동일하게 관찰되었습니다(표 3).
+
+임상적 관련성을 평가하기 위해 3%의 차이 임계값을 설정했을 때,25 UFMI군의 3분의 1 이상에서 **VAI**가 3%를 초과한 반면, 대조군에서는 한 명도 없었기 때문에 그룹 간의 차이가 더욱 두드러졌습니다(표 5). 또한 두 UFMI 연령 하위 그룹에서도 **VAI ≥ 3%**가 관찰되었습니다(표 5). 이러한 결과는 **VAI ≥ 3%**가 비대칭 안면 발육의 조기 진단 도구로 활용될 수 있음을 시사합니다. **VAI**와 유사하게, **RLD(하악지 길이 차이 비율)**도 UFMI군에서 대조군보다 유의미하게 높았습니다(표 2). 그러나 연령을 고려했을 때, 통계적으로 유의미한 **RLD** 차이는 13세 미만 그룹에서만 관찰되었습니다(표 3). **RLD ≥ 3%**에서도 유사한 패턴이 관찰되었으며(표 5), 이는 **RLD ≥ 3%**가 젊은 환자에서 비대칭을 감지하는 도구로 사용될 수 있음을 시사합니다(표 3, 5).
+
+**OC(교합평면 경사)**와 **CD(턱 편위)**는 비대칭이 진행되는 중요한 임상적 징후입니다. UFMI 환자에서 **CD**와 **OC**의 유병률이 대조군보다 유의미하게 높았습니다. 흥미롭게도, 젊은 대조군에서도 **OC** 또는 **CD**를 보이는 환자가 있었으나, 연령이 높은 대조군에서는 **OC**가 전혀 관찰되지 않았고 **CD** 유병률도 낮았습니다. 이는 혼합 치아기에서 영구 치아기로 전환되는 동안 **OC**와 **CD**가 일시적으로 나타났다가 영구 치아기에는 해결
+
+이 연구 데이터를 기반으로 **CD(관절돌기 비대칭)와 OC(교합평면 경사)**는 향후 발생할 수 있는 비대칭을 예측하는 유용한 지표로 활용될 수 있습니다. 특히 **CD는 안면 비대칭 평가에 가장 큰 영향을 미치는 것으로 확인되었습니다**²³. 이러한 지표들이 뚜렷하게 나타나면, 비대칭의 교정 치료가 어려워질 수 있다는 점을 이해하는 것이 중요합니다.
+
+본 연구 결과는 **치료 시기의 결정**에 중요한 의미를 지닙니다. 연령이 증가함에 따라 **OC와 CD의 유병률이 중간 정도지만 유의미하게 증가**하며, 특히 고연령의 UFMI 그룹에서 **OC와 CD 간 강한 양의 상관관계**가 관찰되었습니다. 이는 **대구치 불완전 매복의 적시 진단이 얼마나 중요한지**를 강조합니다.
+
+**조기 개입**은 치열궁의 균형을 회복하고, 원치 않는 치조골 및 골격 비대칭의 발전을 예방하는 데 도움이 될 수 있습니다. 비대칭이 이미 발생한 경우에도, 조기 치료를 통해 잔여 성장 잠재력을 활용하여 치조골 발육과 대칭적인 골격 성장을 촉진할 수 있습니다. 반면, **진단이 늦어지면** 교정 치료만으로는 비대칭을 교정하기 어려울 수 있으며, 심지어 불가능할 수도 있습니다. 이러한 경우, 치료 결과가 타협될 수밖에 없거나, 비대칭을 외과적 방법으로 교정해야 할 수도 있습니다. 이러한 한계점은 **치료 시작 시 치료자가 반드시 이해하고**, 환자와 보호자에게 설명하여 대칭적인 결과를 얻지 못할 경우 발생할 수 있는 좌절감을 예방해야 합니다.
+
+본 연구에는 결과 해석 시 고려해야 할 몇 가지 제한점이 있습니다. 첫째, **이 질환의 희귀성**으로 인해 후향적 연구 설계와 편의 표본을 사용하였기 때문에 선택 편향이 발생할 수 있습니다. 또한, 참가자의 연령 범위(9~27세)가 넓어 아동, 청소년, 성인을 모두 포함하고 있어, 다양한 발달 단계에 따른 결과 해석이 복잡할 수 있습니다. 마지막으로, **현지 보건 규제**로 인해 원뿔빔 전산화 단층촬영(CBCT)과 같은 고급 영상 기법을 사용하지 못했으며, 이는 비대칭 측정에 더 정확한 데이터를 제공할 수 있었을 것입니다. 그럼에도 불구하고, 파노라마 엑스레이는 비대칭 평가에 신뢰할 수 있는 도구로 입증되었습니다²⁵,²⁶. 이는 왜곡이 주로 **수직 차원보다 수평 차원에서 발생**하기 때문입니다³⁶,³⁷.
+
+### **결론**
+본 연구는 **UFMI(불완전 매복 대구치)가 안면 및 골격 비대칭과 관련이 있음**을 밝혔습니다.
+
+1. **UFMI와 관련된 안면 및 골격 비대칭은 연령이 증가할수록 악화됩니다**. 따라서 **조기 진단이 매우 중요**하며, 이를 통해 원치 않는 영향을 예방하고 대칭적인 성장을 유도하기 위한 교정 치료를 시작할 수 있습니다. **소아치과 의사**는 이러한 환자들을 가장 먼저 접하는 전문가로서, **불완전 매복의 초기 징후와 그 골격적 영향**을 인식해야 합니다.
+
+2. **UFMI 진단이 늦어져 비대칭이 이미 발생한 경우**, 치료 결과의 타협이 불가피하며, 이는 환자와 반드시 공유해야 합니다. 또는 **골격적 고정 장치를 사용하거나 악교정 수술**과 같은 더 복잡한 접근법을 고려해야 할 수도 있습니다.

+
+### **요약**
+**배경**: 본 문헌고찰은 상악동 거상술에 사용되는 농축 성장 인자의 잠재력에 대한 최신 연구 동향을 종합적으로 제시한다.
+**재료 및 방법**: "PRP", "PRF", "L-PRF", "CGF", "구강외과", "스티키 본", "상악동 거상" 등의 검색어를 Scopus, Web of Science, PubMed 데이터베이스에서 Boolean 연산자 "AND" 및 "OR"를 사용하여 논문을 검색하였다.
+**결과**: 총 1,534편의 연구 중 22편이 본 고찰에 포함되었다.
+**고찰**: 혈소판 농축물에서 유리되는 자가 성장 인자는 골 재형성과 세포 증식을 촉진하며, 재생 수술 시 자가골 필요량을 줄이는 데 도움이 될 수 있다. 많은 연구자들은 성장 인자가 골 이식 시 초기 혈관 신생을 크게 향상시키고, 동종 이식(alloplastic) 및 이종 이식(xenogeneic) 재료와 결합 시 *in vivo*에서 혈관 형성 촉진 효과가 유의미하다고 보고 있다. 또한 염증 감소, 수술 후 통증 완화, 손상 조직의 재생 촉진 및 치유 가속화에도 긍정적인 영향을 미친다.
+**결론**: 추가 연구가 필요하지만, 자가 혈소판 농축물은 상악동 거상술 시 골 높이, 두께, 수술 부위 혈관화 개선 및 수술 후 치유 촉진을 통해 임상 결과를 향상시킬 수 있는 잠재력이 있다.

+
+### **1. 서론**
+치아 및 치과 임플란트 주변의 치조골과 지지 구조의 보존 및 재생을 위해서는 골 흡수와 골 형성의 균형이 필수적이다[1]. 구강 내 조직 재생은 다양한 세포 유형, 신호 전달 시스템 및 기질 상호작용의 영향을 받는다[1,2]. 임플란트 식립 부위에 심각한 골 결손이 있는 경우 수술이 제한될 수 있으며, 이에 따라 다양한 골 재생 기법이 개발되었다[3]. **상악동 저거상술(Maxillary Sinus Floor Elevation, MSFE)**은 위축된 상악 후방 부위의 골량을 증가시키기 위한 대표적인 술식 중 하나이다[4,5]. MSFE는 상악동의 슈나이더막(Schneiderian membrane)을 거상하고, 수술로 형성된 상악동 저 공간에 이식 재료를 삽입하여 상악 후방부의 골 높이를 증가시키는 것을 목표로 한다[1].
+
+MSFE 및 기타 골 이식 기법(생체재료 이식 포함)의 임상 시험은 보다 예측 가능하고 전략적인 임플란트 지지 보철물을 가능하게 하기 위해 수행되었다[6]. 자가골 이식은 골 유도(osteoinductive) 및 골 전도(osteoconductive) 특성, 면역 적합성으로 인해 오랜 기간 동안 사용되어 왔다[3]. 그러나 자가골 이식에는 공여부 이환(donor site morbidity), 불충분한 골량, 장기 치유 후 골 흡수 등의 단점이 존재한다[7]. 자가골 이식이 가장 생체 적합성이 높은 옵션임에도 불구하고, 이러한 단점들은 대체재료 개발의 필요성을 촉진시켰다[8]. 최근 치의학에서는 환자 자신의 혈액에서 추출한 혈소판 농축 제제가 선호되는 치료 옵션으로 부상하고 있다[9]. 혈소판은 상처 치유 과정에서 골 및 연조직 재생을 돕는 성장 인자와 사이토카인의 저장고 역할을 한다[10]. 활성화된 혈소판은 피브린 기질 내에 네트워크를 형성하고, 조직 치유 기전을 유도하며 궁극적으로 재생을 촉진하는 성장 인자를 방출한다[4]. 혈소판은 혈관 내피 성장 인자(VEGF), 전환 성장 인자-β1(TGF-β1), 혈소판 유래 성장 인자(PDGF), 표피 성장 인자(EGF), 간세포 성장 인자(HGF), 섬유아세포 성장 인자(FGF), 인슐린 유사 성장 인자(IGF) 등 다양한 성장 인자를 함유한 분비 과립을 포함하고 있다[10,11].
+
+자가 혈소판 농축물의 주요 세대는 **혈소판 풍부 혈장(PRP)**, **혈소판 풍부 피브린(PRF)**, **농축 성장 인자(CGF)**로 구분된다[4]. **PRP**는 혈소판 농축물의 첫 세대로, 환자의 정맥혈을 원심 분리하여 얻은 혈소판 농축 혈장으로 골 이식 재료로 사용된다[12,13]. PRP의 항응고제 성분으로 인한 한계를 극복하기 위해, 2000년대 초 Joseph Choukroun은 항응고제 인자를 배제한 제2세대 혈소판 농축물 개발에 주력하였다[14]. **PRF**는 PRP와 유사한 특성을 가지지만, 골 형성 능력이 추가로 향상된 제2세대 혈소판 농축물이다[14]. PRF는 생체 내 트롬빈에 의해 피브리노겐이 피브린으로 전환되므로 첨가제가 필요 없으며, 이는 수술 후 합병증 위험을 최소화한다[9]. **CGF**는 2006년 Sacco에 의해 처음 도입된 새로운 혈소판 농축물로, 연조직 자극 및 치유 가속화, 골 치유 및 형성에서 유망한 결과를 보여주었다[15–18]. CGF는 소량의 혈장에서 CD34+ 줄기세포와 다양한 성장 인자를 농축한다[19]. CGF는 특수 원심분리기(Medifuge, Silfradent srl, Italy)를 사용하여 혈액 샘플을 교대로 조절된 속도로 원심 분리하여 생성된다[20]. 다양한 원심 분리 속도는 PRP나 PRF보다 크고 밀도가 높은 성장 인자 풍부한 피브린 기질을 분리할 수 있게 한다[20]. **스티키 본(Sticky Bone)**은 CGF를 이용한 재생 기법의 진화된 형태로, 원심 분리된 시험관의 액체(백색 평활벽 캡을 가진 시험관에서 수 분 후 젤화됨)와 다양한 종류의 골 입자(인산삼칼슘, BioOss, 치아 변환기로부터 유래된 상아질 등)를 혼합하여 얻어진다[21]. 이를 통해 재생 부위에 쉽게 삽입할 수 있는 치밀하고 가소성 있는 혼합물을 얻을 수 있다. 또한 제제 젤화 전에 잘게 썬 피브린 응고를 추가로 혼합하면 성장 인자가 더 풍부한 혼합물을 얻을 수 있으며, 이는 재생 잠재력을 더욱 높인다[22] (그림 1). 본 문헌고찰은 상악동 증대술에서 자가 혈소판 농축물(PRP, PRF, CGF)과 골 이식을 결합한 치료 및 실험적 잠재력에 대한 최신 연구 동향을 종합적으로 제시하고자 한다.

+
+### **4. Discussion**
+
+#### **4.1. 다양한 혈소판 유도체**
+원심분리 조건에 따라 혈소판 농축물은 PRP(혈소판 풍부 혈장), PRF(혈소판 풍부 섬유소), CGF(농축 성장 인자)로 분류됩니다 [42,43].
+
+**PRP(혈소판 풍부 혈장)**:
+PRP는 성장 인자와 혈소판이 풍부한 저용량 혈장으로, FGF, TGF-β, IGF, PDGF 유사 성장 인자 및 비트로넥틴, 피브린, 피브로넥틴과 같은 세포 부착 분자를 포함합니다. 이러한 구성 성분으로 인해 PRP는 상처 치유를 촉진합니다 [44].
+
+**PRP 제조 과정**:
+정맥혈을 채취한 후 혈액이 응고되지 않도록 항응고제를 혼합합니다. 이 혼합물을 2400rpm에서 10분간 원심분리하면 혈액은 두 층으로 나뉩니다(상층부: 황색 혈장, 하층부: 적혈구). 전체 혼합물을 카눌레이션 기법을 사용하여 두 번째 튜브로 옮긴 후 3600rpm에서 15분간 다시 원심분리하여 튜브 하단에 혈소판 분획을 모읍니다. 이렇게 얻은 것이 수술에 사용되는 PRP입니다 [44].
+
+**PRP의 한계**:
+PRP의 항응고제 성분으로 인한 한계 때문에, 2000년대 초 Joseph Choukroun은 항응고제를 사용하지 않는 2세대 혈소판 농축물 개발에 집중했습니다 [45].
+
+**PRF(혈소판 풍부 섬유소)**:
+이후 2700rpm(750g)에서 단일 원심분리 사이클을 거치면, 응고 인자가 튜브 상단으로 이동하지 않는 혈소판 농축물이 수집되었습니다. 이 제제가 PRF입니다 [46,47].
+
+PRF는 성장 인자와 혈소판이 풍부한 막을 형성할 수 있는 2세대 혈소판 제품입니다. PRF는 또한 섬유소 매트릭스 내에 백혈구(WBCs)를 포함하고 있어 L-PRF(백혈구 및 혈소판 풍부 섬유소)라고도 합니다 [46,48].
+
+**PRF 제조 과정**:
+말초 정맥혈을 채취하여 항응고제가 없는 유리 내벽 플라스틱 튜브에서 2700rpm으로 12분간 또는 3000rpm으로 10분간 원심분리합니다. PRF에는 항응고제가 없기 때문에 혈액을 튜브에 채취하는 즉시 응고가 시작됩니다 [8]. 원심분리 후 상층부에는 세포가 없는 혈장이, 하층부에는 적혈구가 풍부한 층이 형성되며, 중간층에는 PRF 응괴가 형성됩니다. PRF 응괴는 혈소판과 백혈구가 농축된 강력한 섬유소 매트릭스로 구성됩니다 [46,47].
+
+PRF는 주로 혈소판, 섬유소, 혈소판 성장 인자, 사이토카인, 백혈구, 순환 줄기세포, 단핵구, T 및 B 림프구, 호중구 과립구를 포함합니다 [49].
+
+**CGF(농축 성장 인자)**:
+CGF는 2006년 Sacco에 의해 처음 사용된 백혈구 및 혈소판 풍부 섬유소 구조입니다 [50].
+
+**CGF 제조 과정**:
+PRF와 마찬가지로 CGF는 단일 원심분리 방법으로 얻습니다. 적색 캡 실리카 입자로 코팅된 항응고제가 없는 플라스틱 튜브를 사용하며, 이 과정에서는 외인성 물질을 추가할 필요가 없습니다 [50].
+
+혈액을 2400~2700rpm에서 12분간 저속 및 제어된 속도로 원심분리합니다. 그 결과 응괴는 세 층으로 나뉩니다(상층부: 혈소판 빈혈장, 중간층: 섬유소와 CGF를 포함하는 중합된 치밀 섬유소 블록, 하층부: 적혈구). 상층부와 하층부는 버리고, CGF는 버피 코트 층에서 수집됩니다 [51].
+
+**CGF의 특성**:
+2006년 Sacco가 처음 개발한 CGF는 PRP와 PRF보다 더 단단한 섬유소 구조를 가지고 있습니다 [52]. 또한 CGF는 골 재생 및 유방 확대술에서 골형성을 촉진하기 때문에 더 효과적입니다 [53,54].
+
+CGF는 PDGF, TGF-β, VEGF, 인슐린 유사 성장 인자, 상피 성장 인자, 섬유아세포 성장 인자, 골 형성 단백질 및 CD34+ 세포와 같은 성장 인자를 포함합니다 [55]. CGF는 혈관 유지, 혈관신생 및 신생혈관 형성에 중요한 역할을 합니다 [56].
+
+Dai et al.의 연구에서는 GBR(유도골재생술)에서 CGF와 MC(미네랄화 콜라겐)의 효능을 평가했습니다 [19]. CGF+MC를 사용한 환자와 MC만을 사용한 환자를 비교한 결과, 모든 임플란트가 치유되었으며, CGF+MC 그룹에서 부종과 통증이 적었습니다. CGF와 MC의 복합체는 골 증강을 위한 적합하고 효율적인 생체재료로 보입니다 [19].
+
+Ghasemirad et al.의 이중맹검 연구에서는 상악동 거상술에서 CGF가 골 치유에 미치는 영향을 평가했습니다 [29]. 한 쪽에는 소의 이종이식재를, 다른 쪽에는 CGF를 적용했습니다. 알리자린 레드와 헤마톡실린-에오신 염색 결과, CGF 그룹에서 형성된 골의 비율이 대조군보다 유의미하게 높았습니다 [29].
+
+따라서 6개월 후 CGF 그룹에서 새로 형성된 골의 비율이 대조군(이종이식재)보다 유의미하게 높았습니다 [29].
+
+Zhang et al.는 이종이식재(탈단백 우골)와 함께 시행한 상악동 증강술에서 PRF가 골 재생에 미치는 영향을 평가했습니다 [41]. 조직학적 검사 결과, PRF를 사용한 환자와 이종이식재만을 사용한 환자 간에 통계적으로 유의미한 차이는 발견되지 않았습니다. 결론적으로, 이 연구에서는 상악동 증강술에서 탈단백 우골과 함께 PRF를 사용한 경우 6개월 후에도 차이가 없었습니다 [41].
+
+#### **골 조직 재생의 "골드 스탠다드"**
+골 조직 재생의 "골드 스탠다드"는 동일한 환자의 인접 부위에서 채취한 자가이식골입니다 [57]. 그러나 이 방법은 두 번째 수술 절차, 예측 불가능한 흡수 정도, 공여부 부족 등의 단점이 있습니다 [58,59]. 따라서 이러한 단점을 피하기 위해 골 대체재를 사용할 수 있습니다.
+
+상악동 증강술에는 자가이식골, 이종이식골, 동종이식골 등 다양한 이식재가 사용되며, 각각 장단점이 있습니다 [60]. PRF는 혈소판이 연조직 및 골의 발달과 치유에 필수적이기 때문에 다른 이식재보다 더 많은 장점을 가지고 있습니다 [61,62].
+
+**PRP(혈소판 풍부 혈장)**:
+PRP는 환자의 말초 정맥혈에서 원심분리하여 얻은 혈
+
+최적의 골 재생을 촉진하고 수술 중 상악동 막의 완전성을 보존할 수 있었습니다[31].
+
+반면 Kempraj 등[34]은 상악동 거상술에서 Choukroun의 PRP를 단독 이식재로 사용한 경우와 이종이식재(Bio-OSS)를 비교했습니다. 이 연구는 측방 창 기법을 사용한 22건의 시술로 구성되었습니다. 방사선학적 결과에서 PRP 단독 사용에 비해 Bio-Oss 군에서 골 밀도와 골 높이의 유의미한 증가가 관찰되었습니다. 이는 지지 구조물이 없어 PRF 플러그가 상악동 막의 붕괴를 일으켰기 때문으로 보이며, Lundgren 등[65]도 동일한 현상을 보고했습니다.
+
+Powell 등은 L-PRF를 세 가지 다른 방법으로 실험하여 유망한 결과를 보여주었습니다. 첫 번째 환자에서는 양측 상악동 증대술을 통해 상악 하이브리드 덴처를 지지하기 위해 L-PRF를 사용했습니다. 두 번째 환자에서는 Schneiderian 막의 거상에 L-PRF를 사용했으며, 세 번째 환자에서는 L-PRF/이종이식재 상악동 증대술 후 임플란트 식립 6개월 후 조직학적 검사를 실시했습니다[40]. 모든 환자에서 치과 임플란트가 성공적으로 식립되었으며, 두 번째 경우 동결건조 골 동종이식재가 임플란트 식립을 위한 약 4mm의 추가 수직 높이를 제공했습니다. 상악동 증대술 6개월 후 세 번째 사례의 조직학적 결과에서는 이종이식재와 접촉한 신선하고 생존 가능한 골의 형성이 확인되었습니다[40].
+
+Simonpieri 등은 PRP의 효능에 대한 문헌 연구 결과가 명확하지 않을 수 있다고 언급했습니다. 이는 다양한 PRP가 여러 가지 다른 골 재료와 다양한 조합으로 시도되었기 때문입니다[9]. 하악동 하부 절개 시 골 이식재를 관리하는 훌륭한 방법이지만, PRP가 골 치유를 가속화할 잠재력이 있음에도 불구하고, 이 술식의 증거 수준은 여전히 미미합니다. 이는 PRP 없이도 수술 자체가 이미 매우 높은 성공률을 보이기 때문입니다[9]. 수술 방법과 PRP 및 골 이식재의 조합 방식이 연구마다 달랐기 때문에, Simonpieri 등은 다양한 방법론적 변이로 인해 문헌의 다양한 연구에서 광범위한 결론을 도출하기 어려울 수 있다고 주장했습니다[9] (그림 3 및 4).
+
+Tatum은 1976년 Caldwell-Luc 술식을 변형하여 최초의 상악동 거상술을 시행했습니다. 측방 창을 통해 상악동 막을 박리하고 거상했으며(그림 5), 이 경우 상악동에 자가골을 골 대체재로 사용하고 6개월 후 임플란트를 식립했습니다[66]. Boyne과 James는 Caldwell-Luc 상악동 개정술과 측방 창 상악동 바닥 거상을 제안했으며, 임플란트 식립은 3개월 후에 이루어졌습니다[66]. 최초의 상악동 바닥 거상술 이후 다양한 이식 기법과 재료가 제안되었습니다.
+
+1986년 Tatum Jr.는 수술 후 통증과 불편을 최소화하기 위해 경치조 상악동 바닥 거상술을 개발했습니다[67]. Summers는 1994년에 이 접근법을 수정했습니다[68]. 잔존 골 높이가 얇더라도 이식재를 사용하지 않는 Summers의 골 형성술은 제한된 이식의 개념을 발전시키는 데 기여했습니다. 상승된 상악동과 같은 폐쇄 공간에서는 골과 상악동 막의 골형성 잠재력이 잘 보호되고 효과적입니다[69,70].
+
+Simonpieri 등은 24명의 환자에서 측방 창 기법을 사용한 상악동 거상술을 시행했으며, 임플란트 식립 후 2~6년간 추적 관찰했습니다(표 2). 환자들은 상악동 바닥으로부터 치조정 골 높이가 5mm 미만인 하악동 증대 범주 4(SA4)의 상악동 형태를 가지고 있었습니다. Schneiderian 막 보호를 위해 PRF 막을 사용했으며, 임플란트는 L-PRF로 패치된 Schneiderian 막을 지지하는 "텐트 말뚝" 역할을 했습니다. 이 연구에서 임플란트 주변 치조정 골 높이는 일정했으며, 재건된 상악동 바닥 높이는 항상 임플란트의 첨단 가장자리와 연속적이었습니다[71] (그림 6).
+
+실제로 즉각적인 임플란트 식립을 통해 Schneiderian 막을 적절한 높이로 보존할 수 있다면, 이 기법은 성공적인 결과를 가져왔습니다[72]. 그러나 이 기법은 상악동 막의 파열을 허용하지 않으며, 상악동 강저에 혈괴를 채우는 데 어려움이 있습니다[71]. Kaarthikeyan 등은 PRF가 임플란트를 텐트처럼 지지하는 경우 상악동 충전재로 단독 사용 시 효과적인 생체재료임을 결론지었지만, 수술 중 상악동 막의 천공은 만족스럽지 않은 결과를 초래할 수 있다고 보고했습니다[33].
+
+다른 저자들은 측방 접근법으로 이식재 없이 전혈만 사용하여 완전한 상악동 거상술을 수행할 수 있음을 보여주었습니다[73,74]. Chitsazi 등(표 2)은 한 쪽에는 PRF만을 골 이식재로 사용하여 상악동을 거상하고, 다른 쪽에는 이식재를 사용하지 않았습니다. 임플란트는 한 번의 세션에서 식립되었습니다. 이 연구(표 3)는 PRF가 골 흡수의 양과 질을 모두 개선할 수 있음을 보여주었습니다[27].
+
+PRF에 포함된 피브린 네트워크는 삽입 부위에 맞춰 삼차원 구조를 형성하는 경향이 있어 치유 과정을 촉진합니다. 피브린 단량체의 축적으로 인해 부드럽고 다공성 물질의 얇은 망이 형성되며, 이는 해당 부위와 주변 조직의 빠른 세포 정착을 가능하게 합니다[9,75,76].
+
+Molemans 등은 상악동 거상에서 충전재로 L-PRF만을 사용한 연구를 진행했습니다. 치조정 높이가 5mm 미만인 경우에만 측방 창 기법을 사용했으며, 그 외에는 경정중 기법을 선호했습니다(표 2). 이 생체재료가 측방 상악동 수술에서 성공적으로 사용될 수 있음을 보여주었습니다. 임플란트 실패는 경정중 기법에서만 관찰되었으며, 이는 수술 중 막이 천공되었을 가능성이 있습니다[37].
+
+Choudhary 등은 초기 평균 높이가 5.573 ± 0.66mm인 경우 PRF와 유압을 이용한 간접 상악동 거상 및 동시 임플란트 식립의 효과를 평가했습니다(표 3). 수술 후 평균 초기 높이가 유의미하게 증가했습니다(표 2). 6개월 후 임플란트 안정성 지수가 증가했습니다[28]. 이러한 결과는 간접 상악동 거상 및 동시 PRF 임플란트 식립 후 잔존 치조제 높이가 현저히 증가했다는 이전 연구 결과와 일치했습니다[77,78].
+
+Summers의 골 형성술 동안 PRF 막은 충전재로 좋은 결과를 보였습니다. PRF는 골 형성술 중 쿠션 역할을 하며 손상된 Schneiderian 막의 치유를 지원합니다[79]. Huang 등은 측방 창 기법을 사용한 상악동 거상술로 인해 발생한 Schneiderian 막의 천공을 PRF 막으로 수리할 수 있음을 보여주었습니다. Schneiderian 막의 천공은 PRF 막으로 복구될 수 있으며, PRF 막의 피브린과 혈소판 성분이 이러한 효과에 기여할 수 있습니다[30,65,80,81].
+
+1단계 또는 2단계 술식에 관계없이 Rosen 등은 골 형성술 상악동 바닥 거상에서 잔존 치조제 높이가 5mm 이상일 때 임플란트 식립 성공률이 더 높다고 보고했습니다[82]. 다른 저자들은 잔존 치조제 높이가 5mm 미만일 때 실패율이 증가한다고 보고했습니다[83]. 그러나 Li[84]는 초기 안정성이 확보된다면 잔존 치조제 높이가 3~4mm인 경우에도 골 형성술을 적용할 수 있다고 주장했습니다. Krasny 등은 잔존 골 높이가 3~5mm인 26명의 환자에서 경치조 상악동 거상술을 두 단계로 성공적으로 시행했습니다[85].
+
+Aoki 등은 두 증례 보고에서 상악동 거상술을 시행한 결과에 대한 조직병리학적 분석을 발표했습니다. 한 증례에서는 측방 창 기법과 PRF만을 골 충전재로 사용하여 두 단계로 임플란트를 식립했으며, 다른 증례에서는 경정중 접근법과 PRF만을 골 충전재로 사용했습니다(표 2). 두 증례 모두 잔존 골 높이가 2.7mm 미만이었습니다. 조직병리학적 결과에서 PRF가 상악동 내에 존재할 경우 새로운 골 형성을 유도하는 것으로 나타났습니다[25].
+
+Schneiderian 막은 높은 골형성 잠재력을 가지고 있어 대부분의 이식재가 골 발육을 유도하는 이유를 설명합니다[86-88]. 이식재를 사용하지 않더라도 상악동 바닥 거상은 충분한 골 발육과 임플란트 수명을 확보할 수 있습니다[72,89,90]. 그러나 동물 연구에서 Kim 등은 이식재를 사용하지 않은 상악동 거상술에서 골 발육이 제한적임을 보여주었습니다[91]. 또한 Sul 등은 이식재 없이 골 형성이 제한될 수 있으며, 임플란트 첨단이 Schneiderian 막에 걸릴 수 있다고 주장했습니다[92]. 그러나 Simonpieri 등의 연구에서는 PRF 막의 존재가 임플란트 첨단이 상악동 막과 얽히는 것을 방지한다고 보고했습니다[71].
+
+Anitua 등은 양측 상악동 거상술 연구에서 한 쪽은 우골과 혈소판 풍부 성장인자(PRGF)를 사용하고, 다른 쪽은 대조군으로 우골만을 사용했습니다(표 2). 그 결과 PRGF를 사용한 쪽에서 새로운 골 형성이 더 빠르고 치밀하며 치밀도가 높았으며, 우골만을 사용한 쪽은 염증이 더 심했습니다. 환자들은 우골만을 사용한 쪽에서 통증을 호소했습니다[24].

+
+혈소판 유래 제품은 단핵구 사이토카인 방출을 억제하고 염증을 제한하는 것으로 나타났습니다[93]. 또한 혈소판이 활성화된 대식세포에서 인터루킨-1(IL-1)의 방출을 초기 단계에서 차단한다는 새로운 연구 결과가 있습니다. 혈소판 풍부 제품이 항염증제로 작용하는 과정에 대한 광범위한 설명이 가능할 수 있습니다[3].
+
+Lv 등에 따르면, 플랩리스 내시경 보조 골 절개 상악동 바닥 거상술에서 PRF만을 사용한 경우, 측방 창 기법으로 우골을 사용한 상악동 거상에 비해 수술 후 통증과 부종의 발생률이 낮고 환자가 더 잘 견딜 수 있습니다(표 2). 그러나 PRF만을 사용한 경정중 접근법(표 3)과 비교할 때, 우골을 사용한 측방 창 기법이 임플란트 주변 골 높이와 밀도를 더 많이 제공하는 것으로 보입니다[35].
+
+Rapone 등은 7년간 측방 창 기법을 사용한 상악동 거상술 결과를 관찰했습니다[3]. 환자는 두 그룹으로 나뉘었으며, 한 그룹은 천연 다공성 플루오로하이드록시아파타이트와 PRF를 이식재로 사용했고, 다른 그룹은 우골과 자가골(50:50)을 PRP와 함께 사용했습니다. 두 그룹 모두에서 이 연구는 시간이 지남에 따라 예측 가능한 결과를 보여주었습니다(표 2). 이식재를 사용하지 않은 상악동 임플란트와 비교할 때, 이 방법은 더 나은 장기 예후와 더 높은 생존율을 제공합니다[3,94].
+
+Irdem 등은 4개월 동안 우골과 액상 PRF의 조합이 새로운 골 형성을 돕지만, 우골 단독 사용과 비교했을 때 통계적으로 유의미한 차이는 없었다고 보고했습니다[32]. Nizam 등(표 2)도 입자형 DBBM에 L-PRF를 추가해도 조직학적 및 조직형태학적 검사에서 재생된 골의 양이나 새로 형성된 골에 이식재가 통합되는 정도는 증가하지 않았다고 결론지었습니다[39].
+
+Narang 등은 증례 보고에서 잔존 치조제 높이가 1.49mm와 1.47mm인 환자에서 PRF와 골 이식재를 사용하여 상악동 영역에서 10mm 이상의 높이를 달성했습니다. 사용된 기법은 변형된 Summers 기법이었습니다. 이 방법은 상악동을 거상하고 임플란트를 성공적으로 식립할 수 있음을 보여주었습니다(표 2). 이 술식은 일반적으로 6-9개월이 필요한 다른 기법에 비해 3-4개월의 회복 기간만 필요합니다. 이는 상악동 강에 형성된 작은 접근 구멍 때문일 수 있습니다. 이 접근법은 혈류에 거의 영향을 미치지 않습니다. 두 그룹 모두에서 24개월 후 임플란트 성공률은 100%였습니다.
+
+| 연구 | 임플란트 성공률 |
+|------|------------------|
+| | 24개월 후 두 그룹 모두 100% |
+| | 12개월 후 두 그룹 모두 실패 없음 |
+| | 6개월 후 두 그룹 모두 실패 없음 |
+| Lv et al., [35] | PESS—3, 6, 9개월 후 96.15% |
+| | LSFE—3, 6, 9개월 후 100% |
+
+이 기법의 주요 장점은 측방 창 기법과 달리 임플란트와 골 이식재가 대부분 협측에서 혈액 공급을 받는다는 점입니다[38] (그림 7).
+
+또한 Merli 등(Table 2)에 따르면, CGF만을 이식재로 사용한 측방 상악동 저거술은 탈회된 소의 골 이식(DBBM)과 유사한 임플란트 성공률과 미세한 골 수준 변화를 보였습니다[36]. CGF 그룹과 DBBM 그룹 간 변연 골 소실(marginal bone loss)에는 통계적으로 유의미한 차이가 없었습니다(Table 3).
+
+실제로 CGF는 치밀한 피브린 네트워크와 높은 농도의 성장 인자(GF)를 포함하는 차세대 혈소판 제품으로, 세포 증식에 중요한 역할을 합니다[95]. CD34+ 세포는 CGF-RBC의 두 층 모두에서 다수 발견되며, CGF 매트릭스에 다량 포획됩니다. CGF는 골형성 세포의 분화와 증식을 촉진하므로 조직 재생에 더 큰 잠재력을 가지고 있습니다. 그 결과, CGF는 알칼리성 인산가수분해효소(ALP) 활성을 크게 증가시킵니다[52,96].
+
+Chen 등(Table 3)에 따르면, 수술 전 잔존 골 높이가 4~6mm인 환자에서 CGF를 사용한 골막 거상술은 골 이식을 사용하든 사용하지 않든 안전하고 신뢰할 수 있는 방법입니다. 골 이식을 받은 환자는 골 이식을 받지 않은 환자에 비해 수술 후 불편감과 통증을 더 많이 경험했습니다. 그러나 두 그룹 간 변연 골 소실에는 큰 차이가 없었습니다[26].
+
+일부 연구에 따르면, 증강된 상악동에 식립된 임플란트의 생존율은 자가골만으로는 개선되지 않습니다[97-100]. 두 리뷰에서는 자가 블록 이식을 사용했을 때 실망스러운 82%의 임플란트 성공률이 보고되었습니다[98,99].
+
+반면, 자가골 대신 이종골을 사용했을 때 두 리뷰에서 조사된 10,000개의 임플란트 중 96%가 상악동 증강술 후 생존했습니다[97,98]. Forabosco 등의 연구에서 이종골만 사용한 그룹에서는 96.1%의 생존률이 기록되었으며, CGF와 이종골을 함께 사용한 그룹에서는 96.4%의 생존률이 기록되었습니다[101].
+
+Chen 등은 CGF와 골 이식을 함께 사용한 그룹과 CGF만 사용한 그룹 모두에서 100%의 임플란트 성공률을 보고했습니다[26]. 상악동 거상에서 CGF만을 이식재로 사용한 다른 연구들[54]에서도 얻은 골 수준과 임플란트의 성공률이 소의 골 이식과 비교할 만하다고 밝혔습니다[36].
+
+### 5. 결론
+
+결론적으로, 치주 및 임플란트 주위 결손 치료를 위한 다양한 수술 방법이 있습니다. 이는 치골 임플란트부터 골 형성을 증가시키고 가속화할 수 있는 생체재료의 사용에 이르기까지 다양합니다. 치아 발치 후에는 골 흡수 과정이 일어나며, 특히 임플란트 지지 재활을 고려할 때 골 증가가 필요합니다. 상악동 저거술(MSFE)은 골량이 감소된 경우를 해결하기 위한 표준 수술 절차가 되었으며, 치과 임플란트의 위치를 가능하게 합니다. 골 보존 및 재생을 위해 합성 제품부터 이종 또는 자가 이식재에 이르기까지 다양한 생체재료가 제안되었습니다.
+
+조직학적 분석 결과, 성장 인자를 사용함으로써 혈관 신생과 새로운 골의 조기 형성이 촉진되는 것으로 나타났습니다. PRF와 골 이식을 함께 사용했을 때의 유의미한 혈관생성 효과는 재생 과정을 촉진하며, 손상된 골 조직을 새로운 골 세포로 수복하는 신체의 자연적인 능력을 활용합니다. 신생혈관형성을 통한 수술 부위의 혈관화 개선은 수술 상처의 치유를 촉진하며, 특히 상악동 거상술과 같이 혈관화가 감소된 수술 부위에서 특히 유리합니다. PRP 전처리는 일차 안정성을 제공하며, 임플란트-보철 재활을 통계적으로 유의미하게 개선합니다. 다른 골 대체재와 비교했을 때, CGF만을 사용한 상악동 저거술은 탈회된 소의 골 매트릭스와 유사한 임플란트 생존률과 변연 골 수준 변화를 보였습니다.
+
+추가 연구가 필요하지만, CGF, PRF, PRP의 사용은 수술 부위의 혈관화를 개선함으로써 임상 결과를 향상시킬 수 있으며, 환자의 수술 후 삶의 질을 개선할 수 있습니다.
+
+혈소판 유도체는 앞으로 비용, 준비 시간 및 수술 효율성 개선을 통해 더욱 발전할 것입니다. 이는 임상의들이 값비싸고 복잡한 절차임에도 불구하고 임상적 이점이 미미하다고 자주 불평하기 때문입니다.
+
+또한, 이러한 수술 절차의 효과가 임상의의 수술 기술, 이러한 재료에 대한 지식 및 올바른 사용 능력에 크게 의존하고 있으므로, 이러한 절차를 덜 술자에 의존적으로 만드는 방향으로 나아가야 할 것입니다.
