Unilateral Condylar Bone Deformity and Slope of Articular Eminence Related to Mandibular Asymmetry

Abstract

The present study was undertaken to investigate the correlation between condylar position, articular eminence morphology, and mandibular deviation using helical CT in a group of 22 female subjects (mean age 19.2+/-5.3 years) with mandibular deviation. There was a significant difference in the angles of the posterior-slope of the articular eminence (PSA) between the deviated (44.27+/-10.29 degrees) and non-deviated (42.50+/-9.90 degrees) sides. Mandibular deviation also correlated significantly with both medial joint space (r=0.581) and the PSA (r=0.653). A significant negative correlation was also found between mandibular deviation and the anterior/posterior joint space ratio (r=-0.450). These results demonstrated that patients with mandibular deviation possibly show asymmetries not only in their glenoid fossa morphology but also in their condylar position.

“…On the other hand, for chewing by the NXS, 118,119 a steeper condylar path was found on the opposite side, which could explain the patient's difficulty in executing this masticatory movement. This condylar pattern is in line with the one observed by other studies 6 and seems to be the reason for the lower gap for the disc on the balancing side 144 .…”

“…Muscle's passive and active behaviours were simulated with Hill‐type actuators through the parameters described in the above section. On the other hand, the curvilinear surface of the XS was sloped 3 degrees more than one of the NXS 118,119 (shown in Figure 1B,C). The occlusion amongst teeth was defined through a rigid body constraint formulation.…”
