The purpose of this study was to investigate the influences of changes in the horizontal condylar angle and gonial angle on TMJ loading. Based on a juvenile human dry skull specimen, a numerical model of the mandible including the TMJ was developed. In this model, the ramus of mandible is excluded and the condyle and the body of mandible are connected with the rigid elements. The stress distributions on the articular disk during clenching were analyzed with respect to changes in the horizontal condylar angle and the gonial angle. The increased horizontal condylar angle and the narrowed gonial angle resulted in increased stress on the articular disk. It was seen that changes in the horizontal condylar angle and gonial angle influence TMJ loading.
