Numerical Analysis of the Implant - Abutment System

摘要

An important characteristic of dental implants is the configuration of the coupling between implant and abutment. The aim of numerical analysis was calculation of displacements and stresses in an implant system in a function of the applied loading - imitating phenomena in the mouth during mastication. The commonly used internal connection implant complex was modelled in accordance with the geometric designs and scanning electron microscopy observation. Because an excessive stress concentration at the implant-abutment interface is suggested to be critical for the long-term success of implant therapy, the analyses of this aspect can make it possible to evaluate the type of failure of the system and identify its weakest elements. Geometric models of implant systems, were discretized by means of tetrahedron element using the software programs Catia V5.
