The purpose of this study was to evaluate a possible occlusal contributing factor on the pathogenesis of temporomandibular joint sound by a new computer aided method for analysis of occlusal contact. 20 subjects without temporomandibular joint sound as control group and 20 subjects with temporomandibular joint sound as experimental group in the TMJ clinic, dental infirmary, School of Dentistry, Chosun University were selected so as to investigate the distribution and intensity of the bilateral occlusal contacts on silicone rubber bites in habitual intercusal position through a computer aided system. The following results were obtained : 1. The distribution and intensity of the occlusal contact could be analyzed and expressed as color density value per levels by this computer aided method. 2. There was not statistical significance between control and experimental group in total occlusal contacts. 3. There was statistical significance between control and experimental group In the total difference of right and left occlusal contacts.(P<0.05).
