Temporomandibular Joint 😲 | Biomechanics Part 1/2

The video tutorial explains the biomechanics of the temporomandibular joint (TMJ) during mouth opening and closing. It describes the two phases of mouth opening: the early phase, characterized by downward condylar rotation, and the late phase, marked by anterior condylar translation. The tutorial also highlights the role of the lateral pterygoid muscle and gravity in mandibular depression. Additionally, it covers the mechanics of mouth closing, which involves a reversal of the opening process, with posterior and superior translation followed by upward rotation.
