Several etiological factors have been identified with an increased risk associated with implants placed near teeth with periapical lesions. The present study undertook a scoping review to discuss the etiological factors and recent classification of retrograde peri-implantitis and summarize current literature-based guidelines for its management. An online database search was performed to identify studies related to retrograde peri-implantitis using the following terms: retrograde peri-implantitis, implant apical lesions, and periapical implant lesion. A total of 167 studies were initially identified, of which 38 met the inclusion criteria. These comprised case reports and retrospective studies, including 14 case reports that presented various management strategies for retrograde peri-implantitis. Half of these reports describe adjacent teeth with failed root canal treatments or periapical infections. Four studies utilized nonsurgical treatment to manage the lesion, including antibiotics for root canal treatment of the adjacent teeth. The remaining cases involved surgical interventions, such as implant debridement, apical resection, implant removal, and bone grafting. This review discusses the etiological factors of retrograde peri-implantitis, presents the recent classification of the lesion, and summarizes current literature-based guidelines for its management.","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":"376-383"},"PeriodicalIF":1.3,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144144442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To assess outcomes, retrospective chart review and superimposition of preoperative and postoperative cone beam computerized tomography scans were used. The vertical component of the augmented site (L1) was assessed along a vertical bisecting line. Horizontal width was measured in buccolingual dimension at 3-mm intervals (W1-6) along the L1. Paired t tests were used to compare bone measurements at each location, and analysis of covariance models were used to compare the grafting methods. Successes were compared with chi-squared tests.

Molar and incisor crowns were also cemented on screw-retained titanium abutments on titanium implants as control. All specimens were subjected to combined mechanical loading (1.2 × 106 cycles of 50 N, f = 1 Hz) and thermal cycling (2 × 3000 × 5°C/55°C cycles of 2 minutes). Complications, such as loosening of the crowns and fractures, were observed. The surviving specimens were subjected to a fracture test. Descriptive statistics were applied to complications, survival times, and fracture forces. The occurrence of complications depended significantly on location (anterior or posterior) and material (P < .0001). While the incisor test groups presented higher failure rates for both PEKK and zirconia abutments, the survival rates of the molar-shaped crowns of both test groups were comparable with those of the titanium control group. This highly significant interaction is caused by a substantial difference in location for PEKK and zirconia (P < .05). The titanium control group showed uniform performance independent of the simulated site. PEKK abutments showed high survival rates for in vitro simulated molar sites. Screw-retained zirconia abutments have shown higher complication rates, especially in simulated anterior sites. Neither zirconia nor PEKK abutments are recommended in clinical application for anterior indication.","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":"370-375"},"PeriodicalIF":1.3,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144121882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This in vitro study assessed abutment screw loosening in titanium and zirconia implants. Ten zirconia dental implant fixtures (10 mm in length, 4.3 mm in diameter) with 10 zirconia abutments and titanium screws were allocated in one group, and 10 titanium implant fixtures of the same dimensions with 10 titanium abutments and titanium screws were allocated to the other group. The abutment screws were tightened to a torque of 35 N/cm using a torque meter and placed in resin blocks. The center of the resin block then underwent a compressive force of 75 N and 12 400 cycles and a frequency of 75 cycles per minute. Furthermore, the removal torque value of each screw was measured. The data on screw loosening forces were analyzed and compared using a t test with a significance level set at 0.05. The average removal torque for titanium implants was 21.53 N/cm, whereas for zirconia implants, it was 18.46 N/cm. A t test comparison showed that titanium implants had a significantly higher removal torque value than zirconia implants (p < .001). In laboratory conditions, titanium implants exhibit significantly higher removal torque values than zirconia implants, suggesting they may offer better stability in similar clinical settings.","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":"321-325"},"PeriodicalIF":1.3,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144145409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study helps improve implant treatments and reduce the risk of peri-implantitis. This study aims to provide the most recent insights into the therapeutic effectiveness of keratinized mucosa for dental implants that support prostheses. An electronic search was conducted across various databases, adhering to language restrictions and following PRISMA guidelines until August 2024. The PICO study question was: \"For functioning dental implants, how effective is keratinized mucosa in enhancing peri-implant soft tissue conditions?\" The eligibility requirements included all systematic reviews and meta-analyses that examined the impact of keratinized mucosa on the health of implants. Two qualified researchers evaluated the criteria independently while assessing the risk of bias associated with the selected articles. A third investigator is available to resolve any ambiguities that may arise during this process. A total of 10 research studies were found that investigated the impacts of keratinized mucosa on implant health. Involving 7139 participants, the findings indicated that a reduced width of keratinized tissue (KT) was linked to a higher incidence of increased plaque accumulation, soft tissue inflammation, and mucosal recession. The width of KT was notably linked to a reduction in inflammation around the implant. The presence of keratinized mucosa around dental implants correlates with improved peri-implant tissue health and a reduced risk of peri-implantitis. Nonetheless, further data are required.","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":"314-320"},"PeriodicalIF":1.3,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three models were analyzed in the posterior mandible: model A with a distal cantilever, model B with a mesial cantilever, and model C with no cantilevers. Each model included a 4-unit monolithic zirconia prosthesis supported by 2 implants. Under a 200-N oblique load, stress distribution was analyzed in the cortical and trabecular bone, implant components, cement layer, and prosthesis. Fatigue performance was assessed using material-specific S-N curves and fatigue equations. The results demonstrated that models with cantilever extensions exhibited increased stress accumulation, particularly in components adjacent to the cantilever. The highest von Mises stress values were observed in model A, especially on the distal abutment (721.2 MPa), distal implant (313.7 MPa), and prosthetic structure (409.9 MPa). In contrast, model B showed a more balanced stress distribution and lower stress levels than model A. The findings suggest that cantilever presence and positioning significantly impact implant-supported prostheses' biomechanical behavior. With its shorter lever arm and more favorable force distribution, the mesial cantilever was a safer and more effective design option than the distal cantilever, reducing the risk of mechanical complications. These results emphasize the importance of careful design and engineering calculations when planning implant-supported prostheses to ensure long-term stability and minimize the likelihood of failure. This study highlights the biomechanical implications of cantilever positioning in implant prostheses.","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":"361-369"},"PeriodicalIF":1.3,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
