Effects of Condylar Fibro-Cartilage on the Biomechanical Loading of the Human Temporomandibular Joint in a Three-Dimensional, Nonlinear Finite Element Model

The present study was undertaken to test a hypothesis that the addition of articular fibro cartilage in the condyle of the temporomandibular joint reduces three-dimensional stress distribution in the condyle, the disc and articular eminence. A three-dimensional, nonlinear finite-element model was developed for analysis of joint loading before and after the addition of condylar fibro cartilage to the osseous mandibular condyle reconstructed from spiral computer topography data. In the model, each of the disc, condyle and articular eminence was arbitrarily divided into five regions: the anterior, posterior, medial, lateral and central. Von Mises stresses that in virtually all regions of the disc, condyle and articular eminence became lower after the addition of condylar fibro cartilage.
