to learn about TMJ. Opening of the mouth requires the
combination of two motions at the temporomandibular
joint, an anterior gliding motion of the articular disc and
mandible and the downward hinging of the mandible. What
is the initial movement of the mandible during opening and
how much mouth opening does this produce?
