Objectives: The purpose of this study was to evaluate the outcomes of implants placed in horizontally augmented alveolar ridges using porcine bone grafts and to investigate the long-term stability of the porcine bone grafts.
Materials and methods: A retrospective analysis was conducted on 49 sites that underwent horizontal ridge augmentation using porcine bone grafts and implant placement with a follow-up period longer than 5 years. Furthermore, additional analysis was conducted on 24 sites where porcine bone grafts were used exclusively for horizontal ridge augmentation and implant placement.
Results: The mean follow-up period after prosthesis loading was 67.5 months, with a mean marginal bone loss of 0.23 mm at 1 year and a cumulative mean marginal bone loss of 0.40 mm over the entire follow-up period. Of the 49 implants, 2 were lost and 3 did not meet the success criteria, resulting in a survival rate of 95.9% and a success rate of 89.8%. In 24 sites, the mean marginal bone loss was 0.23 mm at 1 year and 0.41 mm at 65.8 months, with 100% survival and success rates.
Conclusion: Porcine bone grafts can be successfully used in horizontal ridge augmentation for implant placement in cases of ridges with insufficient horizontal width.

The mentum plays an important role in the aesthetics of the face, and genioplasty is performed to improve an unbalance of the mentum. Among the various surgical approaches, setback genioplasty is used to create an aesthetic jaw-end appearance by moving the mentum backward when it protrudes more than normal. However, conventional setback genioplasty may be aesthetically disadvantageous because the profile of the mentum could become flat. This case study attempted to overcome the limitations of conventional setback genioplasty by rotating the position of the menton and pogonion. We devised a new method for setback genioplasty by rotating the segment anteroinferiorly. Using virtual surgery, we were able to specify the range of surgery more accurately and easily, and the surgery time was reduced. This case report showed the difference in chin soft tissue responses between conventional setback genioplasty and setback genioplasty with rotation.

The temporomandibular joint is a unique structure composed of the joint capsule, articular disc, mandibular condyles, glenoid fossa of the temporal bone, surrounding ligaments, and associated muscles. The condyle is one of the major components of a functional temporomandibular joint. Reconstruction of large mandibular defects involving the condyle is a surgical challenge for oral and maxillofacial surgeons. To restore large mandibular defects, there are different options for free flap method such as fibula, scapula, and iliac crest. Currently, the vascularized fibula free flap is the gold standard for reconstruction of complex mandibular defects involving the condyle. In the present report, neocondyle regeneration after mandible reconstruction including the condyle head with fibula free flap was evaluated. In this report, two patients were evaluated periodically, and remodeling of the distal end of the free fibula was observed in both cases after condylectomy or mandibulectomy. With preservation of the articular disc, trapezoidal shaping of the neocondyle, and elastic guidance of occlusion, neocondyle bone regeneration occured without ankylosis. Preservation of the articular disc and maintenance of proper occlusion are critical factors in regeneration of the neocondyle after mandible reconstruction.

This case report presents inferior alveolar nerve (IAN) repositioning as a viable approach for implant placement in the mandibular molar region, where challenges of severe alveolar bone width and height deficiencies can exist. Two patients requiring implant placement in the right mandibular molar region underwent nerve transposition and lateralization. In both cases, inadequate alveolar bone height above the IAN precluded the use of short implants. The first patient exhibited an overall low alveolar ridge from the anterior to posterior regions, with a complex relationship with adjacent implant bone level and the mental nerve, complicating vertical augmentation. In the second case, although vertical bone resorption was not severe, the high positioning of the IAN within the alveolar bone due to orthognathic surgery raised concerns regarding adequate height of the implant prosthesis. Therefore, instead of onlay bone grafting, nerve transposition and lateralization were employed for implant placement. In both cases, the follow-up results demonstrated successful osseointegration of all implants and complete recovery of postoperative numbness in the lower lip and mentum area. IAN repositioning is a valuable surgical technique that allows implant placement in severely compromised posterior mandibular regions, promoting patient comfort and successful implant placement without permanent IAN damage.
本病例报告介绍了将下牙槽神经(IAN)重新定位作为下颌磨牙区种植体植入的一种可行方法,下颌磨牙区可能存在严重的牙槽骨宽度和高度不足问题。两名需要在右下颌磨牙区植入种植体的患者接受了神经移位和侧位手术。在这两个病例中,由于IAN上方的牙槽骨高度不足,因此无法使用短种植体。第一例患者的牙槽嵴从前部到后部整体较低,与相邻种植体骨水平和精神神经的关系复杂,导致垂直增量复杂化。在第二个病例中,虽然垂直骨吸收并不严重,但由于正颌手术,IAN 在牙槽骨中的位置较高,这让人担心种植修复体是否有足够的高度。因此,在植入种植体时,采用了神经移位和侧位手术,而不是嵌体植骨。在这两个病例中,随访结果显示所有种植体均成功骨结合,术后下唇和牙槽骨区域的麻木感完全恢复。IAN 重新定位是一项非常有价值的手术技术,可以在严重受损的下颌后部植入种植体,提高患者的舒适度,并在不造成永久性 IAN 损伤的情况下成功植入种植体。

Objectives: This study aimed to compare the effectiveness of a hybrid arch bar (hAB) with the conventional Erich arch bar (EAB) for the management of jaw fractures, focusing on their use for temporary fixation in patients undergoing open reduction and internal fixation (ORIF).
Materials and methods: Patients presenting with maxillary and mandibular fractures at our institution were included in this prospective, comparative study. Placement time and ease of occlusal reproducibility were recorded intraoperatively for Group A (hAB patients) and Group B (EAB patients). The primary outcome was comparison of the postoperative stability of the two arch bars. Postoperative measurements also included mucosal overgrowth, screw loosening or wire retightening, and replacement rates. The data were tabulated and computed with a P<0.05 considered statistically significant.
Results: The study included 41 patients. A statistically significant difference was observed in postoperative stability scores (3) between Group A and Group B (85.0% vs 9.5%, P=0.001). The mean placement time in Group A (23.3 minutes) significantly differed from that in Group B (86.4 minutes) (P<0.001). The ease of intraoperative occlusion was not different between the two groups (P=0.413). Mucosal overgrowth was observed in 75.0% of patients (15 of 20) in Group A.
Conclusion: The hAB was superior to EAB in clinical efficiency, maxillomandibular fixation time reduction, stability, versatility, and safety. Despite temporary mucosal overgrowth, the benefits of hAB outweigh the disadvantages. The choice between hAB and EAB should be based on specific clinical requirements.

Odontogenic keratocysts (OKCs) located in the maxillae have rarely been reported in the literature. Standard treatment modalities for OKC range from marsupialization to marginal resection. However, most of the studies on OKC treatment have been related to mandibular OKCs. The anatomical structure and loose bone density of the maxillae and the empty space of the maxillary sinus could allow rapid growth of a lesion and the ability to tolerate tumor occupancy in the entire maxilla within a short period of time. Therefore, OKCs of the maxillae require more aggressive surgery, such as resection. As an alternative, this report introduces a modified Carnoy's solution, a strong acid, as an adjuvant chemotherapy after cyst enucleation. This report describes the clinical outcomes of enucleation using a modified Carnoy's solution in patients with large OKCs on the posterior maxillae. In three cases, application of a modified Carnoy's solution had few side effects or morbidity. Each patient was followed for four to six years, and none showed any signs of recurrence. In conclusion, adjuvant treatment with a modified Carnoy's solution can be considered a treatment option capable of reducing the recurrence rate of OKC in the maxillae.

Objectives: Concha cartilage is recommended for correction of cleft nasal deformities. Morbidities at the donor site have been reported in esthetic rhinoplasty cases. Reports on cleft patients are limited, so we investigated the complications of concha cartilage harvesting using the retroauricular approach in cleft rhinoplasty and their management.
Materials and methods: This was a retrospective review of the charts of 63 patients with cleft deformities who underwent septorhinoplasty with concha cartilage. All cases were harvested using a retroauricular approach. Data on patient demographics, surgery type, amount of cartilage harvested, and complications were gathered.
Results: Sixty-three patients were enrolled (21 males and 42 females). The mean age of patients was 20.2±5.9 years. Complications were observed in 6 cases (9.5%) and included delayed wound healing (4.8%), prolonged postoperative pain (1.6%), postoperative paresthesia (1.6%), and prominauris (1.6%).
Conclusion: The rate of complications associated with concha cartilage harvesting using a retroauricular approach is low. The use of meticulous surgical techniques, especially hemostasis control and adequate wound dressing, is key to minimizing postoperative complications.

Objectives: Although a few studies have investigated the relationship between kidney and oral function (number of remaining teeth), their results remain inconclusive. Therefore, this study aimed to investigate the relationship between kidney function and oral health in community-dwelling healthy elderlies and examine the factors associated with kidney function.
Materials and methods: We used cross-sectional data from the Shimane prefecture cohort recruited by the Center for Community-Based Health Research and Education in 2019. We collected clinical data on dental status, background factors and kidney function (estimated glomerular filtration rate [eGFR], mL/min/1.73 m2 and creatinine levels, mg/dL).
Results: The study enrolled 481 participants, whose mean age was 66.7±7.4 years, and 223 (46.4%) participants were men. Multivariate analysis revealed significant correlations between eGFR (B=0.17, P=0.04), creatinine (B=-0.54, P<0.01), and the number of remaining teeth. The number of remaining teeth was associated with creatinine and eGFR, which are indicators of kidney function.
Conclusion: This study suggests that preserving the teeth may prevent decline in kidney function. Dental professionals should provide instructions and professional care to reduce the risk of systemic diseases such as kidney dysfunction.

Multivariate analysis revealed significant correlations between eGFR (B=0.17, <i>P</i>=0.04), creatinine (B=-0.54, <i>P</i><0.01), and the number of remaining teeth. The number of remaining teeth was associated with creatinine and eGFR, which are indicators of kidney function.</p><p><strong>Conclusion: </strong>This study suggests that preserving the teeth may prevent decline in kidney function. Dental professionals should provide instructions and professional care to reduce the risk of systemic diseases such as kidney dysfunction.</p>","PeriodicalId":51711,"journal":{"name":"Journal of the Korean Association of Oral and Maxillofacial Surgeons","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10618661/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71428974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A resorbable barrier membrane is commonly used for the repair of perforated sinus membranes during sinus lifting surgeries. However, repairing largescale perforations poses challenges for clinicians as the protection and isolation of graft material remain uncertain. With this technique, we aimed to prevent graft material loss and subsequent sinus-related complications using intra-sinus rigid fixation of the resorbable barrier membrane in cases with a large perforation of the sinus membrane.
