Abstract
Objective To investigate long-term stability of conservative treatment of temporomandibular disorders (TMD). Methods Totally 80 patients with TMD in our hospital from January 2005 to December 2010 were selected as study subjects. All TMD patients were compared 1 to 5 years after conservative orthodontic treatment, and the therapeutic effect of 1 case of conservative orthodontic treatment for 5 years was observed. Results The majority of TMD patients were at the age of 21 to 30. For the 80 cases of TMD, there were 15 cases (18.75%) with limited opening degree I , 10 (12.5%) with degree Ⅱ, 1 (1.25%) with degree Ⅲ, 60 (75%) with open mouth deflection, 35 (43.75%) with clicking of joint, 34 (42.5%) with joint tenderness, 18 (22.5%) with facial masticatory muscle tenderness, 15 (18.75%) with bone changes. Clinical efficacy of orthodontic treatment on TMD patients were not significant different 12, 24 , 36 , 48 and 60 months after treatment (P ＞ 0.05). A patient of TMD was without TMD symptoms 2 years after conservative treatment and had good occlusion. After treatment for 5 years he had no TMD symptoms and could be maintained during the occlusion, his temporomandibular joint functioned well. Concluson Conservative orthodontic treatment can maintain long-term stability of temporomandibular joint function in TMD patients.关键词
