title: A study of the judging the anteroposterior mandibular position by gripping the temporal muscle region.
abstract: Greene proposed a method for judging the suitability of the mandibular position from the bulging of the temporal muscle. Using his method, we studied the effect of anteroposterior alteration of mandibular position on the building of this muscle. In the temporal muscle, the area suitable for gripping to check mandibular position was, anteroposteriorly, the point 3/5 of the length between the upper margin of the external auditory meatus and the point of intersection of the Frankfort plane and the line perpendicular to it which was drawn from the outer canthus. Vertically, it was approximately at the point 3/5 of the distance from the bottom of the line from the Frankfort plane to the upper edge of the temporal muscle. In patients whose anteroposterior changes in the tapping point were small, anteroposterior changes of 0.2 mm in mandibular position could be detected. However, in patients who had large anteroposterior changes in the tapping point, anteroposterior changes of 0.5 mm in mandibular position could not be verified.
