Evaluation of osseointegration and functionality in immediate implant-supported prostheses following sinus lift surgeries: A systematic narrative review.

The evidence-based evolution of dental implantology has made immediate implant-supported prostheses following sinus lift surgeries a straightforward means for the replacement of missing teeth. Achieving primary stability is a key element to the success of osseointegration, especially in cases with limited bone quantity such as the posterior maxilla. A systematic narrative review on the osseointegration and function of immediate implant-supported prostheses in sinus lift surgeries was conducted. To find the articles, we searched databases including SCOPUS, Google Scholar and PUBMED since 2019 to 2024 with using keywords such as immediate implant placement, sinus lift surgery, osseointegration. Studies published only in English which primarily included human subjects and investigated the cause of immediate implant placement surgeries combined with alveolar bone grafting were also selected as inclusion criteria. You can find the thematic structure on this study to classify and analyze. Autogenous grafts, allografts and xenografts performed very well with high successful rates reported by various studies for all types of bone substitutes ranging from 73% to almost perfect conditions (98.3%-grafts; 97.2%-implants). Surface modification of implant like sand/salt blasting and acid etching improves osseointegration with decreased bacterial adherence. Precise surgical techniques were essential to prevent complications such as sinus membrane perforation. Surprisingly, the survival rate of immediate implant placement was high or sometimes equivalent to that for delayed. Improvement in patient satisfaction was achieved by reducing the treatment time and emerging with better functional & aesthetic outcomes straightaway. An immediate implant-supported prosthesis in sinus lift surgery provides advantages of high success rates, less treatment time and more patient satisfaction. Nevertheless, the same meticulous surgical technique and an appropriate choice for graft material and implant surface are mandatory to get a predictable result.
