Purpose: To systematically appraise the clinical and radiological outcomes after osteotome sinus floor elevation (OSFE) with or without grafting in the published dental literature.
Methods: An electronic search was conducted using PubMed, Web of Science, and the Cochrane Central Register of Controlled Trial to identify studies after OSFE from January 1, 1994 to August 30, 2015. The primary outcome was the implant survival rates after OSFE with and without grafting materials.
Results: After search and evaluation of the literature according to the inclusion criteria, 7 studies were included in the review. The random-effect model meta-analysis based on 463 implants in patients without grafting and 415 implants in patients with grafting showed that the risk ratio difference of survival rates was 1.010 (95%CI 0.910, 1.120), which did not reach statistical significance (p = 0.99). The membrane perforation rates ranged from 0% to 10.80%. No significant difference of crestal bone loss was reported between graft and nongraft groups.
Conclusions: Based on currently available evidence, OSFE techniques with and without grafting were both predictable in the short term. In addition, survival rates of dental implants in OSFE with or without grafting did not show any significant difference in the short term.
