The temporomandibular joint (TMJ) connects the mandible to the temporal bone. It consists of the mandibular condyle, articular disc, mandibular fossa, and synovial cavity. Three muscle groups control mandible movement: closing muscles like the temporalis close the jaw, gliding muscles like the lateral pterygoid steer the jaw, and opening muscles like the suprahyoid depress the mandible. Ligaments like the temporomandibular and capsular ligaments also affect jaw movement. The mandible moves in rotational and translational fashions around three axes: the transverse, sagittal, and vertical axes. Basic mandibular movements include hinge
