Designing and Finite Element Analysis of customized titanium plate for Mandible

The Rigid Internal Fixation is one of the commonly used methods to reconstruct the mandible in bone repair surgery. This research proposed a complete flow of the designing and Finite Element Analysis (FEA).The customized titanium plate and screws model were imported in Mimics, then fitted and simulated with the shape of mandible 3D model. The simulation model would be imported into Magic´s and the screw holes were located and punched. In order to ensure the validity of model for surgical guidance, the FEA was employed by FEA software Abaqus in this study. Different angles were selected and different loads were loaded. Comparing with the nomal mandible mechanical data, the von mises stress and deformation which was from the reconstruction of mandible were in the regular range and the RP model which would be used in the medical guidence was manufactured according to the 3D model. The research for this processing has important guide significance and good business prospects.
