Comparative Evaluation of Survival Rate of Implant Placement Using Three Different Indirect Sinus Floor Elevation Techniques: A Systematic Review and Meta –Analysis

Abstract

Introduction: Extreme atrophy of the edentulous maxilla is a common problem that requires augmentation surgery for achieving a sufficient alveolar bone volume allowing for dental implant placement. Lateral sinus membrane elevation for the posterior maxilla is a reliable procedure. The sinus lift procedure is not straight-forward and is associated with complications that may compromise the stability of the graft and the overall success of the treatment, such as the perforation of the sinus membrane, which occurs in more than 20% of cases To investigate the survival rate of indirect sinus floor elevation a systematic review and meta- analysis was conducted.

   Objectives: This systematic review and meta-analysis aim to compare survival rate of three different Indirect sinus lift elevation technique

 Methods: A systematic electronic literature search was conducted through PubMed, The Cochrane   Central Register of Controlled Trials (Central), and Science direct. A hand search was also performed for individual journals and reference lists of selected studies. Randomized controlled clinical trials and crossover clinical trials from 2014 to 2024 with follow up of more than 6 month were included. The Cochrane Collaboration’s tool was used for assessing the risk of bias of included studies.

Results: Three distinct indirect sinus floor elevation investigations totalling nine were completed. To determine the implant survival rate, every study was incorporated into the meta-analysis. The forest plot was created for the indirect strategy (Proportion 0.980, with CI 0.960LL – 0.995 UL), and there is no statistical difference between these indirect techniques.

Conclusions: The survival rate of implants implanted utilizing various indirect sinus lift approach procedures does not differ statistically significantly. As a result, the method is chosen based on the Guidelines provided for every kind of indirect procedure.
