Analysis of the Influence of Parafunctional Loads on the Bone-Prosthesis System: A Non-Linear Finite Element Analysis

The present study evaluates the effects of occlusal loading on an implant-supported dental implant with external hexagon implant-abutment systems, using finite element method analysis. Tensile analyses were performed to simulate different axial and obliquous masticatory loads. influence variations in contouring conditions interfaces was analyzed weigh osseointegration linear non-linear cases, by means a parametric design. geometry selected place prostheses jaw section, considering properties set cortical trabecular bones. results show that for contour conditions, stress presents smaller value distributions signals screw-implant interface as factor greater weight this study. location indicated von Mises concentrations are not exclusive contact regions studied, moving area is direct interfaces. In addition, direction load angle 15 degrees presented highest values stress.
