In anterior gliding of the mandible, there is protraction and retraction. ________ occurs when protraction and retraction of the mandible alternate on the two sides.

A

Grinding

26
Q

In a hinge-like rotation during mandibular depression, the head of the mandible and the articular disc move anteriorly until the head lies (SUPERIOR/INFERIOR) to the anterior tubercle.
