Abstract

Paying attention to the relation between the stomatognathic system and sports performance, the back strength and masseter muscle activity were analyzed, compared, and discussed by using different splints on the left or right of the unilateral occlusion supportive area and the following conclusions were reached.<BR>1. As for back support, there was no noticeable difference among the subjects for the left and right of the occlusion supportive area. A maximum value was obtained when applying a maxillary type splint between the right and left second molars. The value tended to decrease as the occlusion supportive area decreased from the molars to the anterior teeth in a unilateral situation.<BR>2. As for masseter muscle activity, it was found, in all subjects, that the value was maximized whenapplying a maxillary type splint between the right and left second molars. There was also a tendency for the level of the nonsupportive side to decrease significantly compared to that of the supportive side, and for both the supportive and nonsupportive sides to decrease when there was a drop in the occlusion supportive area from the molars to the anterior teeth, in a unilateral situation.
