Using subjects conscious of tempromandibular joint sounds, three-dismensional measurements were taken within the movement of the mandibular border at points where the sounds occured during opening and closing of the mouth. Changes in sound were also observed after fitting splizats. Similar measurements were also taken on patients diagnosed as having a TMJ dysfunction. 1. The mandibular position when sound occured in subjects varied greatly between opening and closing of the mouth. 2. From the characteristic mandibular positions where the TMJ sounds occurred in individuals durinz oteninz and closinx of the mouth, it was possible to divide the subjects into five groups. Splints used were also different according to these characteristics. 3. When the anterior rerositioninx srlint was used on subject in the earlv rhase of opening the mouth, the phase became even earlier. 4. When the stabilization splint was used during opening of the mouth for two of the group with different characterisics, the extent of rosition chanxe in each zroup proved to be different. 5. A rarticular relationshir was observed between the chanzing sound positnon and the splint fitting, which suggests a relationship between the sound position and the cause of the TMJ sound and the effect of splint therapy.
