TMJ Biomechanics | Mandibular Elevation

The video tutorial explains the arthrokinematics of the temporomandibular joint (TMJ) during mouth closing. It covers mandibular elevation, the two components of closing (translation and rotation), and the role of muscles like the masseter, temporalis, and medial terrago aids. The tutorial highlights the importance of eccentric contraction by the lateral terrago aids to control the articular disk's movement and prevent tissue damage. The process involves posterior and superior translation followed by upward rotation, with specific muscle involvement ensuring controlled and effective jaw closure.
