Piezoelectric Surgery Versus Conventional Rotatory Burs for Sinus Lift Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Abstract

Objective: The aim of this study is to compare the outcomes after implementation of piezoelectric bone surgery versus conventional rotatory devices in sinus lift surgery. Methods: A systematic review of MEDLINE (via PubMed), Scopus and Cochrane Library database was performed (last search date: 04 March 2022) according to the PRISMA guidelines. Only randomized controlled trials that directly compare the two techniques were included. Random-effects model meta-analysis were performed. Results: Six studies, comprising a total of 140 patients/ 259 sinuses, 130 undergoing sinus lift with piezoelectric osteotomy device and 129 with conventional rotatory burs were identified and five of them were included in our meta-analysis. The two techniques were compared for intraoperative membrane perforation and operative time. No statistically significant difference was observed regarding membrane perforation (Standardized Mean Difference [SMD]: 0.87, 95% Confidence Interval [CI]: [0.33] – [2.28], p=0.78, I2= 0.00%) and operative time (SMD: 0.76, 95% CI: [-0.09] – [1.60], p=0.08, I2=77.70%). Conclusions: Data seem to agree that both piezoelectric osteotomy and osteotomy with conventional rotatory burs have similar results in membrane perforation and operative time when used for sinus lift surgery.
