Temporomandibular joint (TMJ) disorders affect 20 to 25% of the population and include pain dysfunction, arthritis, and internal derangements. The pig is a common model due to its similar structure and mechanics to humans. This work represents the first finite element analysis (FEA) of pig TMJ. The primary objective was to investigate the stress distribution pattern in the TMJ articulating disc. The TMJ disc was defined as a Mooney-Rivlin material. Geometry was obtained from CT scans. Retrodiscal and TMJ ligaments were included as linear springs. The disc was considered glued to the mandible, but had frictionless contact with the temporal bone. Muscle loads were used to simulate clenching. It was observed that the TMJ disc followed the condylar motion. Also, significant lateral movement of the mandible was observed. The intermediate-lateral part of the disc was most stressed. The observed stresses were comparable to the human TMJ models in magnitudes and locations.
