抄録

It is well known that the range of motion during mouth opening changes with the food size.<BR>We have previously reported the relation of head movement to the mandibular movement; the head moves in the extended direction during mouth opening. In this study, we analyzed the head movement simultaneously with the mouth opening during food intake.<BR>One male and two female adults (age range: 24-26yrs.) without any craniomandibular dysfunction were selected as subjects. The test food consisted of an apple cut into the different square size (6 to 35mm) . Then, we recorded the head and mandibular movements at two head positions (horizontal to the Frankfort and Camper plane) with the 6-degree-of-freedom measuring device without any restrictions of the subjects' head.<BR>The results were as follows:<BR>1) The food space was observed during food intake. The size of this space at the same food size was kept constant even when the head position was changed.<BR>2) The head movement was larger when the head position was horizontal to the Frankfort plane than to the Camper plane. This suggests that the head movement exists in order to acquire support for the mandible during mouth opening.
