Modélisation numérique de l'os mandibulaire appliquée à l'implantologie dentaire et maxillo-faciale

Abstract : The increasing use of implant dentistry requires the development of innovative techniques adapted to complex maxillo-facial configurations. To manage theses difficult cases and to insure and improve the results stability over time , it is necessary now to get a better understanding of the mechanical implications of the fonctional implant loading.To reach this goal, a numerical model of the mandibular bone has been set up.The objective is to study the stress distribution within the bone and in the neighbourhood of implants.A first stage of this work has been devoted to the identification of the elastic properties of the cortical mandibular bone by the use of an advanced inverse analysis methodology.This coupled experimental – numerical approach has been validated and leads to a reliable numerical approach to study implant dentistry.The second stage of this work deals with the use of the numerical simulation to study the stress distribution around an implant inserted laterally (Diskimplant®) in a mandibular bone.Numerical simulation are validated experimentally and give promising results in the field of implant dentistry.
