Biomechanical Investigation of Resilient Dental Implant Design by Finite Element Analysis

Abstract

This study investigated the biomechanical behavior of implant design that forms an integral part of tooth-implant support prostheses. The research presents a 3D finite element analysis for three different models, one of which was designed with a shock absorber implant. To make the study more qualitative, implant design has been compared once with the classical tooth-implant support prostheses model and once again with the tooth-support support prostheses model.  The prostheses model with the resilient implant of the cushioning element shows impressive results since they reduce the von Mises stresses and the over-mechanical loading around the natural tooth and implant under various loading conditions. Finally, it concluded that a resilient implant with a cushioning element design transfers stresses more efficiently than other implant designs, and successfully handles the biomechanical problems related to combining natural teeth with implants.
