    Abstract:
    OBJECTIVE: This study was performed to evaluate the position and morphology of the temporomandibular joint in female patients with skeletal class II malocclusion and to investigate the association between temporomandibular joint disorders and facial types using cone-beam computed tomography. METHODS: A lateral cephalogram was taken to determine the skeletal class of each participant. Sixty female patients aged 16 to 28 years were divided into high-angle, low-angle, and control groups. The shape of the condyle-fossa was measured and assessed on cone-beam computed tomography images of the 120 temporomandibular joints. RESULTS: Some condylar shape measurements displayed statistically significant differences among the groups. No significant differences were found in the length of the condyle, width of the glenoid fossa, or height of the articular eminence among the three groups. The posterior condylar position was more frequently observed in the low-angle group, whereas the anterior condylar position was more prevalent in the high-angle group. CONCLUSION: The present study revealed differences in the condyle-fossa morphology and position in female patients with skeletal class II malocclusion with different vertical facial types.
