Motions at temporomandibular joint
- A joint created between the mandibular head and mandibular fossa (temporal bone) via an articular disc. It performs occlusal (masticatory) movements. The characteristics of the movement are that it is a combination of the following movements, that it is accompanied by the movement of the articular disk (it is not a simple hinge joint), and that the left and right joints work together.
- Vertical movement of the mandible between the articular disc and the head of mandibule
- Anterior-posterior movement of the mandible between the articular tubercle of the temporal bone and the articular disc
- Lateral movement of the mandible due to the movements described above alternating between the left and right joints
