Research Abstract

The purpose of this study was to analyze the three-dimensional occlusal contacts in intercuspal position in normal adults and to discuss about the criteria of occlusion in upper premolars and molars. The silicone occlusal registration was taken for each of five normal adults with no caries and no restoration at 30% of maximum voluntary clenching in intercuspal position. The silicone occlusal registration was digitized by non-contact three-dimensional form measuring device. The 3-D data were analyzed by CAD software with a personal computer. The flame of reference was established using upper occlusal plane. The occlusal contact area was calculated for an intraocclusal distance of less than 60 μm. The occlusal surface of upper first and second premolar was classified into four parts ; buccal cusp, lingual cusp, mesial marginal ridge and distal marginal ridge. The occlusal surface of upper first and second molar was classified into six parts ; mesial buccal cusp, distal buccal cusp, mesial lingual cusp, distal lingual cusp, mesial marginal ridge and distal marginal ridge. The number, rate and orientation of occlusal contacts were analyzed. The region and orientation of the most frequent occlusal contact area in upper premolars and molars in normal adults were indicated.
