Abstract

Abstract: Objective: To assess the changes of condylar morphology in different conservation treatments through systematic review of relevant randomized controlled trials, and to provide image evidence for the treatment of temporomandibular joint osteoarthrosis. Methods: 90 patients were randomly divided into 3 groups and given different conservative treatments. The condylar morphology and clinical symptoms were evaluated after 3 months and 9 months. The clinical parameters recorded were Fricton′s Craniomandibular index (CMI), maximal mouth opening (MMO), pain intensity on a visual analog scale (VAS), and CBCT radiographic data of 113 TMJs from 90 consecutive TMJ patients. Results: The surface of the condyle became smooth, the density of the cortical bone and the adjacent subcortical bone increased and osteophyte in condylar head decreased after 9 months treatment. In terms of the changes of the condylar bone, the group of joint injection plus stabilization splint were better than the other group (P<0.05). CMI, MMO, and VAS were significant decreased after 3 months and 9 months, but there were no significant differences among three groups (P>0.05). Conclusion: Joint injection plus stabilization splint can promote the bone remodeling on the surface of condyle. Comparing to the other conservative treatment, it is an appropriate treatment for temporomandibular joint osteoarthrosishe.
