Purpose: The aim of this systematic review is to evaluate the survival rate of implants placed using indirect sinus floor elevation with and without bone grafts.
Material and Methods: The electronic databases, such as MEDLINE, EMBASE, PUBMED and CENTRAL were systematically and manually searched. Thirteen studies fulfilled the inclusion criteria. The included articles were subjected to quantitative analysis, and Le meta-analysis was carried out.
Results: The included studies were of moderate quality, with overall implant survival rate for grafted implant to be 96.50% and for nongrafted implants 97.40% after follow-up period of more than 1 year. This indicated that the osteotome sinus floor elevation technique with or without grafting were both predictable.
Conclusion: Within the limitations of the study, it can be concluded that the implant survival rate for grafted and nongrafted maxillary sinus are predictable. And we can assume that there are many other factors affecting the survival rates of dental implants with osteotome sinus floor elevation in grafted and nongrafted implants.
