A customized subperiosteal titanium maxillary implant (CSTMI) was designed using virtual surgical planning (VSP), stereolithographic (STL) models, and CAD/CAM technology. The CSTMI framework, incorporating endosseous implants, was secured to the orbital rims and pterygoid plates to optimize prosthetic stability and load distribution.

At the one-year follow-up, minor screw loosening was successfully managed without complications. CSTMI represents a viable alternative for maxillary reconstruction in patients unsuitable for traditional implants, providing functional and aesthetic rehabilitation.

However, the relationship between these complications and the repetitive tightening and loosening of the central screw during the fabrication and maintenance of the implant-supported restorations remains unknown. The purpose of this study was to evaluate the torque loss after repetitive tightening and loosening of the central screws on implants with different diameters as well as the changes in the angle deviation of the central screw relative to the implant. Twenty implants were divided into 2 groups based on diameter: 3.7 mm (group A) and 4.5 mm (group B) with 10 implants in each group. Each group was subdivided into 4 subgroups: A1, A2, B1, and B2 (n = 5). A closing torque of 15 N.cm was applied to groups A1 and B1, whereas a closing torque of 35 N.cm was applied to groups A2 and B2. Reverse torque measurements were taken 10 times for each group. The angular deviation of the central screw relative to the implant was recorded, and the surface wear of the central screw was observed under a scanning electron microscope. The data were analyzed using repeated measures 2-way analysis of variance (α = 0.05). Torque loss showed a significant upward trend across all groups with increased tightening cycle (P < .05). Implant diameter significantly influenced torque loss with smaller diameters exhibiting greater torque loss (P < .05). In addition, the angular deviation of the central screw relative to the implant was not affected by different diameters (P > .05). Still, it was affected by the closing torque and the cycles of multiple tightening and loosening procedures (P < .05). Under a 35 N.cm closing torque, initial torque loss ranged from 9.12 N.cm to 10.98 N.cm. Peak torque loss occurred at the 10th cycle with 16.40 N.cm values for 3.7-mm implants and 12.42 N.cm for 4.5-mm implants. Repeated tightening and loosening procedures increased both torque loss and angular deviation. The diameter of the implant may impact the torque loss with a larger diameter showing less torque loss. To reduce the risk of potential complications, it is suggested that the number of tightening cycles for narrow-diameter implants be limited.</p>","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":"202-209"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143470152","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}

Although dentomaxillary prostheses are common, they frequently lead to instability and reduced chewing ability. Vascularized bone grafts, including the fibula, are increasingly used to address these challenges due to their anatomical suitability and functional restoration benefits. Despite advances, problems remain, including insufficient bone height for stable implantation. A 60-year-old Japanese woman presented with swelling of the right maxilla and nasal obstruction and was diagnosed with osteosarcoma. Following chemotherapy and partial maxillary resection, she experienced discomfort with dentomaxillary prosthetics, prompting subsequent reconstruction with fibula and particulate cancellous bone and marrow (PCBM) grafts. This patient was taking methotrexate regularly for rheumatoid arthritis, so there was concern that she would be immunosuppressed. Therefore, we did not choose a zygomatic implant, which would be difficult to control in the event of infection. In addition, the fibula alone was insufficient for reconstruction; sufficient vertical and horizontal bone augmentation was required, and we chose a combination of titanium mesh and PCBM that met these requirements. Sequential implant procedures culminated in fixed superstructures that significantly improved occlusal function and prosthetic stability over a 6-year follow-up period. This case highlights the challenges of prosthetic instability following maxillary resections and demonstrates the effectiveness of multistage reconstructions using fibula grafts and PCBM for alveolar ridge augmentation. The structured approach to maxillofacial reconstruction provides valuable insights into optimizing functional outcomes following surgical procedures and highlights the importance of tailored treatment strategies in complex maxillofacial cases.</p>","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":"172-179"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143191698","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}
