Effects of the Geometric Parameters on the Interfacial Stresses Bone/Implant

Abstract

Implantology is the fixation of an artificial root made of titanium in the mandibular bone, emerging from the gum and supporting atooth or prosthetic element. In this work, the mechanical behavior of dental implants with different geometric shapes is analyzednumerically by the finite element method. The first objective of this study is to show the importance of the geometric parameters suchas length on the variation of the equivalent stress in the close vicinity of the bone / implant interface. These interfacial stresses areevaluated on the outside and inside of the net. The results clearly show that the best model of the implant obtained is that of 10.43 mmin length. The second objective is focused on the distribution of von Mises stress in the bone and the dental implant in different loadingcases. It is important to know the effects of this type of treatment to obtain a primary stabilization of the structure or at the interfacebone/implant.
