Mandibular joint (temporomandibular joint) has basically two parts: mandible caput and glenoid fossa which is located on the cranial base. There is a temporomandibular disk between these two bone surfaces; and the caput quasi lapses on this mandibular ribbon. The joint is held by special ribbons from the outside. The movement of the joint is not just a simple turn but a forward and backward slip combined with a mandibular joint rotation.
- Ankylosis (bone adhesion between joint surfaces)
- Pseudoankylosis (soft tissue adhesion between joint surfaces)
- Trismus, i.e. lockjaw (spasmodic traction of the jaw muscle; mostly it is the result of a wisdom tooth inflammation)
