The aim of this study was to investigate factors associated with double contour formation (DCF) in mandibular condyle by comparing magnetic resonance (MR) images obtained before and after splint therapy. Disk position, cortical bone status of condyle, and joint fluid were evaluated for 6 temporomandibular joints (5 patients) with DCF. For comparison, the remaining 4 joints without DCF were also included in the evaluation. All of the 6 joints with DCF showed the anterior disk displacement before therapy while the 4 joints without DCF showed the normal disk position. After therapy, the disk position of all joints with DCF was improved. Two joints with DCF showed cortical erosion before therapy and their erosive changes disappeared after therapy. Four joints with DCF showed large joint effusion before therapy and they disappeared or diminished after therapy. According to these results, it can be concluded that double contour formation is associated with improvement of disk position and joint fluid.
