Anatomy of temporomandibular joint and condyle position in Uygur adult patients evaluated with cone-beam CT

Abstract

Abstract: PURPOSE: To compare the anatomy and condyle-fossa relationship difference between Uygur adult patients with Class I and Class Ⅱ division 1 malocclusion by three dimensional cone-beam CT (CBCT). METHODS: Sixty-four patients with Class I and Class Ⅱ division 1 malocclusion were selected, and the CBCT scans of their temporomandibular joints were taken.The difference of the condylar morphology and location between Class I and Class Ⅱ division 1 patients was analyzed with SPSS 17.0 software package. RESULTS: The position of condyle in the TMJ fossa was not significantly different between the two groups; in Class Ⅱ division 1 malocclusion group, the mandibular fossa depth, anterior joint space and the superior joint space were significantly bigger (P<0.05), but the posterior joint space was significantly smaller than those in Class I malocclusion group (P<0.05). CONCLUSIONS: There were difference in condyle position and TMJ morphology between Class I and Class Ⅱ division 1 malocclusion group in Uygur adult patients.
