Finite element model of fixed denture aided by Mimics & Geomagic / 医用生物力学

Objective To establish a 3D finite element model of fixed denture for the preparation of the subsequent study such as biomechanical analysis. Method The computed temography(CT) images were processed by Mimics and Geomagic studio，then the solid model and finite model were established by UG NX. Results A 3D finite element model of fixed denture including alveolar bone, abutment, pericementum and denture were established. Conclusions The use of the initial data of teeth to build finite model can avoid data loss and minimize model distortion to a certain extent, so the 3D finite element model has good similarities in geometry.
