Abstract

Abstract: PURPOSE: To analyze the relationship among condylar position and gender and craniofacial bone morphology in adolescent patients with skeletal malocclusion. METHODS: Odontic simulation software (Dolphin imaging11.8) was used to reconstruct cone-beam CT(CBCT) images of 391 patients with different skeletal malformations aged 15-16 years.The anterior, superior, and posterior spaces of temporomandibular joint(TMJ) were measured on the sagittal plane of the condyle to calculate the relative position of the condyle. The difference of condylar position between different genders, sagittal, and vertical skeletal types were analyzed, and the correlation was evaluated by a multivariate logistic regression model with SPSS 23.0 software package. RESULTS: Univariate analysis showed that the condylar position was different between different sagittal facial types and gender(P<0.05). Compared with men, the OR value of anterior condylar displacement in female was 1.942(95%CI: 1.166-3.236, P=0.011). The greater of the right articular eminence angle, the easier the condyle moved backward, and the OR value was 1.032(95%CI: 1.000-1.066, P=0.048). CONCLUSIONS: The articular eminence angle may be related to the posterior displacement of the condyle, and female condyle is more likely to move forward than male.
