[The effects of a total TMJ endoprosthesis on the contralateral condyle].

Electronic axiography found that patients in the postoperative period could restore some of the translational movements even with the attachment of the lateral pterygoid muscle cut off. The main factor influencing the magnitude of the endoprosthesis translational movement is the design of the fossa component: the ratio of the circumferential surface of the fossa to the diameter of the head of the endoprosthesis, as well as the presence of lateral stoppers. The study showed that unilateral TMJ reconstruction provides changes in the volume of the native joint directly related to the amplitude of the movement of the joint itself and inversely correlated with the amplitude of the movement of the endoprosthesis.
