Abstract

Abstract:

Objective　Mandibular condylar defects in the finite element model is established to study the new artificial temporomandibular joints stress distribution and displacement of the change. Methods Mimics, Geomagic, Solidworks, ANSYS software were used to establish complete denture mandibular condylar defects on the right side of the finite element model and analyze the new TMJ condylar prosthesis in simulation of the bite force load of mandibular condylar prosthesis and hard tissue stress distribution and displacement.　Results　The whole Mandibular equivalent stress values were smaller than 20 Mpa, the maximum deformation value was smaller that 0.05 mm.　Conclusions　New artificial temporomandibular joints can avoid prosthesis fracture and bone absorption caused by excessive stress , and has a good biomechanical properties.

Key words: New type, Artificial temporomandibular joint, Biomechanics
