Crestal Bone Loss Changes in Platform Switching around Dental Implant: A Systematic Review & Meta-Analysis

Abstract

Introduction: The exact mechanism by which platform switching reduces bone loss is still unkown, and there are only few reports on the extent of bone loss prevention by this technique. Hence in our study we assess the effects of platform switching in patients restored with implant supported fixed restorations on implant failure and patient satisfaction.

Materials and methods: We searched the online data bases with the search words platform switching. Implant failure, crestal bone loss. We searched for various types of studies and trials. Also the number of the sample was not restricted. Two independently reviewers evaluated trials for accurateness. The results were stated as risk ratio or mean differences, with their 95% confidence intervals. The primary outcome was patient satisfaction and implant failure.

Results: Out of the 500 studies only 12 were included. No difference between platform switching and matching in three years in implant failures was noted or patient satisfaction. Marginal bone loss, due to the disparities in the study was not meta-analyzed in our study.

Conclusions: From our analysis we can conclude that with respect to the implant success and patient satisfaction, by the platform switching, there is no sufficient data to support.
