Abstract
The purpose of this study was to investigate the relationship between condylar rotation and translation during habitual closing late phase in 20 patients with unilateral or bilateral reciprocal TMJ clicking and to compare it with the results obtained from 19 normal subjects to determine whether or not there is any relation with clinical findings.The results were as follows:1. The amount of condylar translation from 0.2 to 0 degree of rotation angle (designated 0.2 T value) was 1.44±1.25 mm. The amount was a larger value and had a wider range than that of normal subjects, which was 0.40±0.22mm.2. Patients were divided into group A (7 patients) whose closing click occurred before 0.2 degree of rotation angle, group B (8 patients) whose closing click occurred after 0.2 degree, and group C (5 patients) whose closing click position was unclear. The 0.2 T value of groups A and C was 0.59±0.38 mm and 0.39± 0.19 mm respectively which was near to the normal subjects' average. However, the0.2 T value of group B was 1.44±1.25 mm, which was much larger than that of normal subjects.3. Patients who had a small 0.2 T value tended to have good prognosis. It was clarified that the 0.2 T value could be an effective parameter for the prognosis of judgment.
