The relationship between the body balance laterally and the gnathodysfunction we often doubted through daily clinic.
The purpose of this study was to investigate the relationship between the morphological balance, and the functional balance of the body and the stomatognathic function.
Subjects of this study were composed of fiftynine young adults. The following items were examined on the subjects;
1. The distribution of the center of gravity position.
2. The difference of the height among both shoulder.

In addition the jaw movement on chewing and the electromyograms of the bilateral masseter and temporal muscles during clenching were simultaneously recorded from three subjects.
The results obtained were as bellows;
1. A slight relationships were found between left and/or right dominancy and habitualmasticating side, and between posture and habitual masticating side were found.
