Abstract:
Objectives: To study the clinical meaning of condyle-form asymmetry and its osseous changes shown on TMJ images of lateral oblique transcranial projection and lateral tomography. Methods: 113 patients with partial posterior teeth lose were enroled in the study.Among them 25 were with temporomandibular disorder (TMD group),39 with slight TMD sings (sub-TMD group) and 45 without TMD(TMD-free group). Radiographs were taken and studied for each patient. Results: It was found that the condyle form asymmetry and osseous changes were not significantly different among the three groups. Osseous change was related to the number of teeth-lose (P0.05). The symptoms and signs of TMD had close relationship with occlusal interferences. Conclusions: The changes shown on TMJ images do not show close relationship with TMD symptoms and signs. Occlusal interferences resulted from teeth-lose are related to the clinical symptoms and signs of TMD.
