A 3D-FEA of Temporomandibular Joint with Reduced Curvature of Curve of Spee

Abstract:

Temporomandibular joint (TMJ) is a weight-bearing joint^[1] ,its biomechanical environment is closely related to bite force. Morphological characteristics of occlusal is an important guide to the bite force conduction. This conduction has an important impact on environmental stress in TMJ. Spee curve is one of the important morphological features of dentition,but study of its curvature changes in relations to joint stress is rarely reported . This study aimed to analyze stress distribution in TMJ when curvature of Curve of Spee decreased. In this study, two kinds of 3D model with diffirent curvatures of Curve of Spee were designed. Model 0: the normal, the curvature was 2.50mm. The vertex was at the cuspis of the second premolar. Model 1: the curvature was 0. Then analyzed by 3D-FEM. The final results validated that the anterior surface of condyle and intermediate zone of articular disc were the weight-bearing areas in TMJ. The stress increased along with curvatures of Curve of Spee decreased.
