[Study on stress distribution of the condyle].
The stress distribution in the condyle was calculated by means of combining CT examination with computed image operating technique and three-dimensional finite element models. The results suggested that there was a higher stress level in condylar cortical bone than in cancellous bone. Stress on the cortical bone were shown to concentrate in middle and lateral 1/3 part of articular surface of the condyle. The distribution of stress on two condyles was symmetrical. That analysis method of biomechanics was introduced into the clinical and baic study on the temporomandibular joint provided a new means for helping diagnosis and treatment of the temporomandibular joint diseases.
