Response of temporomandibular joint intermittent closed lock to different treatment modalities: A multicenter survey

This study investigated the clinical picture and different treatment methods and results at a number of institutions with the aim of establishing an effective method of treatment for intermittent closed lock (intermittent lock) of the temporomandibular joint (TMJ). The subjects were 104 patients (29 males, 65 females) diagnosed with intermittent lock among 1787 temporomandibular disorder patients. The cases were classified into two types based on the time and occasion when the intermittent lock occurred. The sudden onset type developed in 69.2%, and the habitually occurring type in 29.8%. The most common treatment was disk repositioning exercises alone (in 41 cases) followed by stabilization splints during sleeping. The highest efficacy rate (60.0%) was obtained with the combination of disk repositioning exercise and a repositioning splint followed by a rate of 52.6% with stabilization splints and 41.7% with disk repositioning exercise alone.
