The experimental verification of the efficacy of finite element modeling to dental implant systems

The experimental verification of the efficacy of finite element modeling to dental implant systems

Journal of Oral Implantology 22(2): 104-110

In vitro experimental data of angular displacement vs. applied force were obtained on a fully osseointegrated pair of endosseous implants in a mandible of a macaca mulatta monkey. These data are compared with calculated displacement data for a given force from a three-dimensional finite element model reproducing the geometric structure of a portion of the mandible holding the implants. The displacements show agreement over a range of forces in the elastic region within 3%. The FE model yields a full description of the bending of the implant and the distribution of the stress in the bone surrounding the implants.
