Abstract: Objective To determine the relationship between the occlusal support and the condyle position by cone beam CT(CBCT). Methods A total number of 84 patients who were treated at our institution from 2013 to 2016 were retrospectively included. The space of the bilateral joints and the condyle position were measured with NNT on CBCT multiplanar images. The association between the condyle position and occlusal support was statistically analyzed. Results The mean distances of the anterior, superior and posterior joint space were (2.23±0.79)mm, (1.98±1.18)mm, (3.53±0.99)mm respectively. The occlusal support was classified into type A(22), type B(31) and type C(31). The superior and posterior joint spaces were significantly associated with occlusal support. However, no significant relationship was found between occlusal support and anterior joint space. The condyle position was defined as anterior(39 sides), concentric(48 sides) and posterior(81 sides).The distribution of condyle position was associated with occlusal support. Conclusions There is a significant correlation between occlusal support change and the condyle position.
