摘要

Dental Implants' popularity have increased over the years, in oral rehabilitation of lost teeth due to trauma or periodontal diseases. With that, the number of clinical implantation procedures failing have increased as well. Methods to simulate how an implant will behave in terms of stress and strain in the mandibular bone subjected to masticatory forces are required in order to predict its behavior. Finite Element Method (FEM), has been described to be a good method for assessing this problem. In this work, an implant will be created by a 3D CAD (Computer Aided Design) tool SolidWorks and manipulated in software that works with 3D mesh models, to be then analyzed in an educational program FEMAS (cmech.ewbs.com) by FEM method. It was verified that the depth of the implant in the mandibular bone positively influences the stress and strain distribution in the implant during the chewing movements.
