The Fatigue Simulation Analysis of Customized Implanted Titanium Plate for Human Mandible Bone Reconstruction

Abstract

Aiming at the implanted mandible titanium plate in chewing movement under the action of repeated load is prone to fracture, leading to problems such as secondary surgery. This study makes fatigue simulation analysis for customized implanted titanium plate of fatigue damage. It also analyzes the minimum service life position and low service life area on different loading. Simulation analysis of deformation is done. The analysis contains the deformation area and the maximum deformation degree with a variety of bite condition. This study also analyzes and forecasts the fatigue failure area, which provides basis for preventing fatigue failure for implanted titanium plate. It has important significance to improve titanium plate service life and strength. It also could alleviate patients’ sufferings.
