[Roentgencinematographic studies on the mechanics of the tempero-mandibular joint. Function of the tempero-mandibular joints in patients fitted with full dentures (author's transl)].

Investigations of the articular mechanics of the tempero-mandibular joint are an important element in gnathology. Graphically recorded movements of the condylus obtained by extra-oral mechanical aids, only give information about the projections of the articulatory pathways. Only roentgencinematography allows a profound study of the articular mechanics.

[Radiocinematic comparison of the movement of the temporomandibular joint in the same patient with total prosthesis after various jaw relation recordings].

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.
