Objective To establish a three-dimensional finite element model of normal temporomandibular joint system and surgical treatment on mandihular condylar fractures three-dimensional digital model in order to supply a digital plat form for biomechanical research of TMJ. Methods CT and MRI scanning data of normal TMJ were used to establish intact three-dimensional finite model of TMJ and surgical treatment on mandihular condylar fractures ,using Mimics, Geomagic and ANSYS software. Biomechanics of the TMJ model was analyzed to verify the validity of the model. Results An intact three-dimensional finite element model of TMJ and surgical treatment on mandihular condylar fractures was established successfully, and the model provides a precise anatomic morphology of the temporomandibular joint. Conclusion It is precise and feasible to construct a 3-D FEM of the TMJ system based on CT images,MRI images and anatomy by means of Mimics and Geomagic Stadio and Ansys.This model can restore the biomechanics environment of the TMJ, and provide new ideas of modeling for research on biomechanics of the TMJ.
