Weight distributions on soles of feet in the primary and early permanent dentition with normal occlusion.

This study investigated the differences of weight distribution on the sole of the feet in the primary and the early permanent dentition by the modifying Morton staticometer. The distribution of body weight in the outer forward part on soles of feet in the permanent dentition group was significantly greater than that in the primary dentition group. The distribution of body weight in the heel on soles of feet in the permanent dentition group was significantly smaller than that in the primary dentition group. These results indicated that the weight was shifted from the heels to the forefeet from primary to permanent dentition.
