The effect of the stabilization splint on the TMJ closed lock

The mandibular manipulation technique and anterior repositioning splint are considered acceptable conservative therapies for an acute temporomandibular joint (TMJ) closed lock. However, an anterior repositioning splint will result in a corresponding change in occlusion, such as posterior open-bite. Furthermore, invasive treatments such as surgery have many complications. This article describes the effect of the stabilization splint with more conservative therapies, including the manipulation technique, wherein the complications are minimal. In this study, the authors used the stabilization splint instead of the anterior repositioning splint. They obtained acceptable results, including the increase of interincisal distance, a decrease in Fricton's craniomandibular index, and a decrease in Helkimo's clinical dysfunction index. Therefore, the treatment method that is composed of a stabilization splint, manipulation, moist heat, and exercise should be considered as the first choice of treatment for TMJ closed lock, as opposed to a repositioning splint.
