Abstract

Background and Aim: The goal of this study was to investigate the stability of a DENTAL IMPLANT which is implanted in clinical models of the mandible and to evaluate the effectiveness of strength, radius and thickness of the bone around a DENTAL IMPLANT by using finite element method.Materials and Methods: A 3D wire frame model of the mandible was developed based on computer tomography data of a 25-year-old subject in MIMICS. This model was smoothed in CATIA. Finally, a 3D model of the DENTAL IMPLANT was assembled in the mandible and FINITE ELEMENT ANALYSIS was done on the model with various material properties, loading condition and constraints in ABAQUS.Results: In the clinical models, the highest stress was found in the mandible with a thin layer of cortical bone around the core of the cancellous bone with the lowest density. It was shown that increase of the cortical bone radius resulted in the decrease of stress in the mandible. The 2 mm thickness of the cortical bone around a DENTAL IMPLANT was evaluated as the critical thickness of the bone.Conclusion: Increase of stiffness of the cortical or cancellous bones resulted in increase of the stress in that specific part of the bone. In addition, the increase of the bone thickness was more considerable in less than 2 mm thicknesses.
