[How do occlusion disorder and stress influence cybernetic masticatory control?].
Chewing forces were registered and compared in three subjects under normal conditions as well as in presence of occlusal interferences, and under stress. Biting force, blood pressure, and concentration of blood catecholamines were measured. Psychic stress was induced by demanding reactions on a test machine. In the presence of occlusal interferences, no significant increase in biting force was recorded. However, the biochemical analysis documented that biting forces appeared to be no longer under local control, but, increased up to 600% when the level of stress was raised. This study confirms the importance of stress as an etiologic factor in masticatory dysfunction.
