  • Title: [Radiocinematic comparison of the movement of the temporomandibular joint in the same patient with total prosthesis after various jaw relation recordings].
    Author: Gernet W, Puff A, Steinkraus Ch.
    Journal: Dtsch Zahnarztl Z; 1977 May; 32(5):385-90. PubMed ID: 266457.
    Abstract:
    Six edentulous patients were each provided with two complete dentures and the relation of the jaws to each other was determined by means of both the conventional checkbite and a combined Gerber arrow-angle registration. Cineradiographic evaluation of the temporomanidibular joint movements did not confirm a bony or ligamental guidance, but showed that the condyle path is characterized by neuromuscular coordination. In four patients there was no characteristic difference in the form of condyle path when using the two dentures. But the condyle paths differed strikingly in those patients who had temporo-mandibular complaints or neuromuscular disharmonies. The paths were clearly steeper with Gerber dentures than dentures made after the conventional check-bite. In laterotrusion the "active" condyle moves on a straight line towards the from and downward, while the relatively "resting" condyle describes a shortened path corresponding to the initial part of an opening movement.
