Comparing the functional efficiency of tooth‑supported overdentures and implant‑supported overdentures in patients requiring oral rehabilitation: A systematic review

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.
