Abstract
In is known that posterior open bite has come about the reduction of the articular disk in the closed locking temporomandibular joint. However, there are few reports about the orthodontic reconstruction of this posterior open bite.
This clinical report indicates that dento-alveolar compensation resulting from orthodontic treatment is very effective in the reconstruction of the posterior open bite caused by the disk recapture of the TMJ.
Furthermore, in this long progressed closed lock of the TMJ, fibrous adhesion of the superior articular cavity was identified by double contrast CT. Also, arthroscopic surgery using Nd: YAG laser is effective in tearing off the fibrous adhesion.
