| Research Abstract |
The new features about the masticatory activities during unilateral clenching were suggested in the present study, which differed from the previous electromyographic studies. Especially, the present results suggested that the superior head of the lateral pterygoid muscle was controlled independently from other masticatory muscles, and the activity of superior head of ipsilateral lateral pterygoid muscle increased in association with the changes in the occlusal point from the first molar to the first premolar during unilateral clenching.
