The effect of direct and indirect force transmission on peri-implant bone stress - a contact finite element analysis
Abstract
In almost all finite element (FE) studies in dentistry, virtual forces are applied directly to dentures. The purpose of this study was to develop a FE model with non-linear contact simulation using an antagonist as force transmitter and to compare this with a similar model that uses direct force transmission. Furthermore, five contact situations were created in order to examine their influence on the peri-implant bone stresses, which are relevant to the survival rate of implants. It was found that the peri-implant bone stresses were strongly influenced by the kind of force transmission and contact number.
Keywords: Non-linear contact analysis; finite element analysis; occlusal loading area; peri-implant bone stress; prosthodontics.
