In this paper, we make a study about the effects of 6 different kind of arrangement of the 1st molar in maxillary complete denture on the stress distribution of bone tissue. In intercuspation position, it is well-distributed when the artificial teeth are arranged on the top of alveolar ridge. There are stress concentration in the bone tissue. When the long axis of the teeth incline bucally or the teeth migrate away from the ridge center line. When the ridges relation is disharmonious, it is better that the teeth incline do not over 30 degrees buccally and the teeth migration do not over 5 mm horizontally.
在本文中，我们研究了上颌全口义齿中第一磨牙6种不同排列方式对骨组织应力分布的影响。在正中咬合位时，人工牙排在牙槽嵴顶上应力分布均匀。当牙长轴颊倾或牙齿偏离牙槽嵴中线时，骨组织会出现应力集中。当牙槽嵴关系不协调时，牙齿颊倾度不超过30度且牙齿水平向移位不超过5mm为宜。
