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.

本研究的目的是分析正常成人牙尖交错位咬合关系的三维结构，并探讨上颌前磨牙和磨牙咬合关系的判定标准。对5名无龋、无修复体的正常成年人在牙尖交错位最大随意咬牙合30%时进行硅橡胶咬合记录。采用非接触式三维形态测量仪对硅橡胶咬合记录进行数字化。三维数据用计算机辅助设计软件进行分析。以上牙合平面为基准建立参考框架。计算咬合接触面积，咬合间距离小于60 μm。将上颌第一、第二前磨牙的咬合面分为颊侧尖、舌侧尖、近中缘嵴和远中缘嵴四部分。将上颌第一、第二磨牙的咬合面分为近中颊侧牙尖、远中颊侧牙尖、近中舌侧牙尖、远中舌侧牙尖、近中边缘嵴和远中边缘嵴6个部分。分析咬合接触的数量、比率和方向。指出了正常成人上颌前磨牙和磨牙最频繁接触区的位置和方位。
