Abstract

The current study aimed to determine the correlation between the condylar morphology in skeletal Class III pattern by using cone-beam computed tomography and the crown inclination of lower anterior teeth. Materials and Methods: This study examined the bilateral TMJ CBCT images of 30 subjects (17 males, 13 females) with skeletal class III, average age (1830 years), and lower cast. The TMJ's angular and linear measurements were estimated, and variances between the groups were statistically examined. The torque and angulation device TAD was used to measure the inclination of the crowns. Results: Regardless of the joint reference points used for measurements, there is no correlation between the position and mutual relations of the lower anterior teeth and the temporomandibular joint's structure. Conclusion: The mandibular condyle height was greater in Class III malocclusion. Men had larger mandibular body sizes and wider mediolateral condyles than women did.
