| Research Abstract |
It is important to clearfy the food form suitable for the mastication capability of child to promote education, but it is difficult to analyze a jaw movement using equipment in a child. So this time, aiming to objectively evaluate lip and mandibular movements when chewing, the movements of the corners of the mouth and the mandible during mastication were measured three-dimensionally and analyzed. The analysis result showed that X- and Z-axis movements occurred on the working-side corner of the mouth, with Z-axis movements preceding X-axis movements, while on the balancing-side cornerof the mouth, X- and Z-axis movements occurred simultaneously.
