Abstract

Abstract: Objective: To analyze the relationship between the position and morphology of condyle and anterior teeth occlusion by CBCT. Methods: The bilateral joint space and depth were measured to analyze the relationship between anterior teeth occlusion and TMD in 47 TMD patients using CBCT examination. Results: No significant changes were found in bilateral joint in all patients. There was close association between anterior teeth occlusion and condylar position, in which the condylar of overbite combined overjet patients and sole overjet patients were moved backward (P= 0.011 and P=0.0004). The incidence of osteoarthrosis was increased in patients whose anterior teeth occlusion was normal (P=0.005). Conclusion: The etiology of TMD is complex and multifactorial. Occlusal condition is just one factor.

Key words: Condylar, Glenoid fossa, Joint space, Cone-beam computed tomography
