BACKGROUND: Maxillary sinus floor augmentation without grafts has been more widely used, but the efficacy is still controversial.
PURPOSE: The aim of this review was to systematically evaluate the effectiveness of sinus floor augmentation without grafts in atrophic maxilla.
METHODS: The electronic databases included PubMed, EMBASE and the Cochrane Central Register of Controlled Trials. The meta-analysis was conducted by Review Manager 5.1. The quality of evidence was assessed using the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE).
RESULTS: The electronic database and manual search yield 707 studies. After critical selection, only 6 studies were eligible. Five studies with 336 implants were included in the meta-analysis compared sinus augmentation with grafts to without grafts. No significant differences were found between the two groups in implant survivals (P = 0.94), marginal bone loss (P = 0.73) and new bone density (P = 0.54). There was significantly more endosinus bone gain in the grafting group (P = 0.02). According to the GRADE, the levels of evidence were moderate (implant survival and marginal bone loss), low (endosinus bone gain) and very low (new bone density).
CONCLUSION: There were no significant differences between maxillary sinus augmentation with and without grafts in short-term implant survivals.
