Occlusal disease is a disease caused by a discrepancy between habitual occlusal position and muscular position. The muscular position is defined as the mandibular position when it has been closed by voluntary muscular activity with an upright posture. The habitual occlusal position is an arbitrary (habitually) closed position. Generally, the muscular position on is coincident with the habitual occlusal position. However, in an appreciable number, it is not. And in these people, various symptoms would be manifested. To remove a patient’s occlusal habit and obtain a physiological muscular position, the bite plate-induced occlusal position is used during voluntary jaw closing, while in an upright position and after wearing an anterior bite plate for a short period of time. The discrepancy between the habitual occlusal position and the muscular position is related to some symptom using the bite plate-induced position. The symptoms include oral dyskinesia, glossodynia, burning mouth syndrome, tension-type headache, tinnitus, otitis, vertigo, and coxalgia etc.. Some of these symptoms will be presented and discussed.
