Movements of the Mandible
The articulating joint of the mandible allows for a combination of movements, such as
- lateral, and
- protrusive movements.
Different types of teeth perform various functions
- incisors and cuspids for cutting
- bicuspids and molars for crushing
The articular disc is situated between the condyle and the fossa to allow for the many different movements and functions required by different teeth.
To contain the TMJ and to seal in the synovial fluid, the TMJ is encapsulated by the capsular ligament with a synovial lining.
Thus, the TMJ is protected from wear and can absorb minor blows to the jaw.
