Numerical analysis of the effect of implant geometry to stress distributions of the three different commercial dental implant system

Abstract

Objectives: The success of dental implants is related to the quality, quantity of local bones,implant design and surgical technique. Implant diameter and length are accepted as keyfactors. Present work focuses to investigate the effect of titanium implant geometry to stressdistributions in implant system. Materials and Methods: For this purpose three different implant models which are currentlybeing used in clinical cases constructed by using ANSYS Workbench 12.1. The stress distributionson components of implant system under static loadings were analyzed for all models. Results: The maximum stress values that occurred in all components happen in the case ofloading in which the Nucleoss T-4 (Nucleoss, Turkiye) implant is used, but the occurred loweststress values happen in the case of Fı loading in which Nobel Active (Nobel Biocare, Zurich,Switzerland) implant is used. In all models, the maximum tensions have occurred in the neckregion of the implants. Conclusions: The crestal bone loss in the neck region of the implants reduced the long-termsurvival rate of implants.The length and the size of the implant are the two important factorsin the stress distribution.
