ABSTRACT
The aim of this article is to compare the functional efficiency of tooth-supported overdentures and implant-supported overdentures in patients requiring oral rehabilitation. The comparative quantification of the improvement in functional efficiency is very difficult to assess because of the variations in the study designs like the age of the population studied, the male-to-female ratio, the outcome measures used, the clinical setting in which the implant therapy was provided, oral status of the subjects included and the type of implant therapy provided. In this systematic review, the articles included compared the functional efficiency by assessing the bite force, chewing efficiency, electromyographic (EMG) changes measured by EMG analysis, and patient satisfaction for subjects who have been rehabilitated with either a tooth-supported overdenture or an implant-supported overdenture. This will help the clinicians to better plan the treatment, keeping in mind the long-term prognosis for that particular patient.
