[The masticatory muscle synchronizer. Guided functional therapy of myoarthropathies of the tempors-mandibular joint].

In the myoarthropathies of the masticatory organ, psychic factors, often coupled with occlusal disturbances, have a trigger function. If the psychic factors prevail, the disturbances of the occlusion as etiologic factors diminish or are totally absent. In such patients, we often find fronto-lateral bruxism without any premature contacts in evidence. A guided functional therapy is introduced. With the so-called synchronator for masticatory muscles, a backfeed programming of the dysfunctional mandibular motion pattern is provoked into the normal neuromuscular harmony. This is done by obtaining centric relation and by blocking the fronto-lateral parafunctional pattern by rebuilding measures.
