- Introduction: This review aims to explore the prosthetic factors that affect marginal bone loss (MBL) in dental implants and to provide evidence-based insights to improve clinical outcomes and ensure long-term implant success. Materials and Methods: A total of 236 articles were initially retrieved through database searches using keywords such as “implant design,” “platform switching,” “emergence profile,” and “marginal bone loss,” and 38 were selected based on relevance, methodological rigor, and level of evidence, with preference given to systematic reviews, meta-analyses, and recent studies. The selected studies were narratively summarized based on the following topics. Results: Internal connection implants showed significantly lower MBL than external connection types. The emergence profile, particularly the emergence angle, was identified as a critical factor for peri-implant bone stability, with over-contoured designs being associated with increased MBL. Residual cement at subgingival margins posed a significant risk of peri-implant inflammation and bone loss. Fixture length and diameter had limited direct effects, but deeper implant placement was associated with greater initial MBL while reducing thread exposure over time. The crown-to-implant ratio and cantilever design were associated with biomechanical stress and bone loss.Conclusion: Splinting improved load distribution and implant survival rates, but also increased hygienic challenges and the risk of peri-implantitis. - COLLAPSE

- Introduction: Maxillary sinus augmentation is a technique widely used to address insufficient bone height in the maxillary posterior region caused by bone resorption and sinus pneumatization. We aimed to reviews the lateral sinus augmentation procedure and identify key factors for success.Materials and Methods: This study included 31 patients who underwent lateral sinus augmentation achieve successful bone graft outcomes without resorption or failure between January 2024 and March 2025. Preoperative and postoperative radiographs and intraoperative photographs were analyzed, and the procedures were compared with those in the existing literature.Results: The incision line and lateral window designs used in this study were consistent with those reported previously. Although this study used the removal and repositioning method for lateral window management, other studies have used grinding and infracture techniques. The use of specialized kits for sinus membrane elevation have been highlighted in some studies for safety and convenience; however, this study demonstrated that a the use of a 45° Freer elevator alone was sufficient. Fibrin glue has been used to improve graft handling and barrier effects during bone grafting and window repositioning, whereas other studies have reported similar success using barrier membranes.Conclusion: Lateral sinus augmentation is essential for implant placement in the posterior maxillary region. The key factors for success include proper incision and window design, careful membrane elevation, appropriate graft selection, and tension-free suturing. When performed correctly, this approach ensures predictable outcomes with results comparable to those achieved using advanced equipment or alternative techniques. - COLLAPSE

- Purpose: This retrospective study aimed to evaluate the clinical performance of milled-bar and solitary attachment combination-supported prostheses in partially and fully edentulous patients with a follow-up period of more than one year.Materials and Methods: Patient information, dental records, and X-ray images were provided by an information technology specialist at Pusan National University Dental Hospital without personal data. Definitive prosthetic types and occlusal schemes were classified, along with categorization of the number and types of implants inserted. Additionally, cumulative survival rates were evaluated using the Kaplan–Meier method and marginal bone loss was assessed using panoramic radiographs and fixture length information. Various complications that occurred during the post-prosthetic restoration follow-up examinations were collected and categorized. Results: A total of 74 cases were included in this study, involving 68 patients. Among them, six patients had both maxillary and mandibular arches restored using milled-bar and solitary attachments. The cumulative survival rate for all implants was 92.5%. There was no statistically significant difference between the follow-up period and marginal bone loss around the implants. The most common complication after prosthetic restoration was the replacement of solitary attachment supplements, followed by issues related to the prostheses and problems related to the milled bar. Conclusion: Thus, with respect to prosthetic restoration using a small number of implants with milled bars and solitary attachments, satisfactory clinical outcomes were achieved without marginal bone loss around the implants. - COLLAPSE

- Purpose: Edentulous maxillary rehabilitation with implants is a crucial treatment modality to enhance masticatory function and quality of life. Primary prosthetic options include implant-supported fixed prostheses and implant overdentures; the optimal treatment choice depends on patient-specific factors. In the present study, we established the selection criteria for implant treatment in patients with maxillary edentulism. Materials and Methods: A total of 26 patients with maxillary edentulism were included, with 10 patients receiving fixed prostheses and 16 receiving overdentures. Variables such as mean age, number of opposing natural teeth, maxillary residual bone height, number and location of maxillary implants, economic status, and presence of severe systemic diseases (uncontrolled diabetes, anticoagulant use, and history of malignancy) were analyzed.Results: Patients in the fixed prosthesis group had a mean age of 65.2 years, an average of 9.1 maxillary implants, 7.5 opposing natural teeth, and a mean residual bone height of 13 mm, with 10% having severe systemic diseases. Those in the overdenture group had a mean age of 72.8 years, an average of 4.4 maxillary implants, three opposing natural teeth, and a mean residual bone height (cortical bone to sinus floor) of 8 mm, with 30% having severe systemic diseases. Fixed prostheses were primarily supported by bilateral central incisors, canines, one premolar, and two molars, whereas overdentures were supported by canines and second premolars or lateral incisors and first premolars.Conclusion: Patients who received fixed prostheses were younger, and had more opposing natural teeth, greater residual bone height, fewer systemic diseases, and better financial status. This study contributes to the definition of selection criteria for implant-supported maxillary prostheses for patients with edentulism - COLLAPSE

- Immediate implant placement (IIP) is a feasible treatment option for replacing a single tooth in the maxillary anterior region, offering a favorable long-term success rate and the advantages of reduced surgeries and overall treatment time. However, as IIP does not prevent resorption of the alveolar ridge dimensions after tooth extraction, additional hard and/or soft tissue grafting procedures are often considered to compensate for post-extraction ridge alterations, augment the buccal ridge contour, and improve esthetic outcomes. In this study, we report two cases of single IIP in the maxillary anterior incisor, combined with simultaneous bone grafting of the horizontal gap and buccal soft tissue augmentation using connective tissue harvested from the maxillary palate. Both patients showed favorable buccal ridge profiles without specific complications and were satisfied with the esthetic outcomes. Within the limitations of a short-term follow-up period, simultaneous bone grafting and soft tissue augmentation using a connective tissue graft in the IIP of a single tooth in the anterior maxilla is considered a reliable treatment option for maintaining the buccal ridge contour and soft tissue stability. - COLLAPSE

- Full-mouth rehabilitation with implant-supported prostheses presents challenges in regard to restoring function, esthetics, and occlusion, particularly in patients with severe periodontal disease and extensive tooth loss. Recent advancements in digital technology, including intraoral scanning, digital occlusal analysis, and face scanning, have enabled the precise fabrication of customized prostheses and improved occlusal stability. This case report describes the application of advanced digital techniques in managing complex full-mouth rehabilitation cases and demonstrates their potential to enhance the accuracy, efficiency, and clinical outcomes. - COLLAPSE
