Abstract
An apparatus for exercise of the temporomandibular joint. The apparatus consists of a maxillary mold attachment means pivotally attached to pins which are inserted to a stationary portion of an actuation device, and a mandibular mold attachment means pivotally attached to pins which are inserted to the traveling portion of an actuation device. The actuation device provides vertical motion to exercise the joint. The attachment means includes extension means including a hollow cylinder and a piston to accommodate the required horizontal displacement of the jaw during opening and closing, the pivot means to accommodate the curvelinear motion of the jaw when opening and closing. A method of therapy using the disclosed device provides improved bite gap for patients undergoing TMJ surgery.
