Assessment of the Temporomandibular Joint Morphology in Class II Malocclusion using Cone Beam Computed Tomography.

Abstract

Introduction: the morphology of the temporomandibular joint (TMJ) in people with diverse forms of malocclusion has not been properly examined. Aim: To assess the temporomandibular joint morphology in Class II Malocclusion using Cone Beam Computed Tomography. Material and methods : A total of 48 CBCT scans were collected and divided into two groups according to the divisions of Class II malocclusion. The TMJ morphology in patients with class II malocclusion and comparison between groups 1 and 2 was done as well as right and left TMJs in each scan. The following measurements are made on the CBCT images. Measurements in The Corrected Sagittal Plane. Measurements in the Axial Plane. Results : results of the current study showed that there were no statistically significant differences between the right and left sides in each group regarding the anterior joint space, superior joint space, posterior joint space, and depth of glenoid fossa associated with sagittal plane. In addition, there were no statistically significant differences between the groups regarding the anterior joint space, superior joint space, posterior joint space, and depth of glenoid fossa associated with sagittal plane. C onclusion : Temporomandibular joint morphology did not differ between Class II division 1 and Class II division 2.
