[The effect of teeth arrangement in maxillary complete denture on the stress distribution of bone tissue--photoelastic stress analysis].
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.
