Description: A three-dimensional working model of the masticatory system was created in Cinema 4D(c) using cadaveric muscle fiber bundle data for the masseter, temporalis, medial pterygoid and lateral pterygoid muscles, as well as information collected for the tendons, skull and mandible. In this model of the passive movement of the muscles of mastication, the muscle fiber bundles are represented as elastic bands stretched between their two points of attachments. The motion of the mandible during jaw opening was animated, and the resulting movements of the muscles of mastication were observed on a fiber bundle level. Measurements were taken throughout the duration of the animation to determine the changes in lengths and angles of pennation for the fiber bundles of the masseter muscle. These measurements were used to validate the passive movement model. Finally, the creation of more sophisticated masticatory models using the derived measurements was discussed.
