[Stress distribution in the periodontal tissue around roots of an inclined abutment by 3-D photoelasticity].
The stress distribution in the periodontal tissue around roots of a mesially inclined mandibular second molar as the the abutment of a fixed bridge was analysed by the three dimensional photoelasticity. It was shown by 3-D photoelasticity that the stress distribution in the alveolar bone around the roots of the abutment was modified by the placement of the fixed bridge. The maximum stress points in alveolar bone around the roots of abutment were also located.
