Abstract:
Objective: To investigate the factors related to the of disc displacement in temporomandibular joint disorder(TMD). Methods: The angles of disc anterior displacemen were measured on arthrography of temporomandibular joints in 90 patients with TMD, then the relationship between the angles and symptoms, signs, condyle positions, osteoarthrosis and mouth opening degree were analysed. Results: ①AOB angle in the patients with reducibility of anterior disk displacement(ADwR) was smaller than in those with non reducible anterior displacement (ADw/oR); ②Patients suffered from chronic ADw/oR had smaller degree of mouth opening and larger disc displacement than those with ADwR's. Conclusion: The disc anterior displacement and condyle displacement in glenoid fossa may be correlated with articular remodeling.Prolonging coursees may not always result in the changing of disc structures.
