Abstract
Occlusal disease is a disease caused by a discrepancy between habitual occlusal position and muscular position. Th e
muscular position is defi ned as the mandibular position when it has been closed by voluntary muscular activity with an
upright posture. Th e 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 aft er wearing an anterior
bite plate for a short period of time. Th e discrepancy between the habitual occlusal position and the muscular position is related
to some symptom using the bite plate-induced position. Th e 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.
