Outline of Final Research Achievements

Food intake during weaning period has been paid little attention. However, this motion may be crucial for the development of oral morphology and function. Three-dimensional measurement and analysis of this motion was performed, however, children of this period were too young as subjective person to obtain the precise data. Their food intake motions consisted of the backward tilting motion of the head rather than the downward motion of the mandible.
Measurement of the motion of the mandible during mastication from female adults revealed that the weight of the subjective foods affected the entire cycle time and ranges along three orthogonal axes.
