A kinematical study of bite force during voluntary isometric contraction was
investigated in 25 removable space maintainer wearing children as the experimentals and
40 children as the normals, ranging from 4 to 8 years old.
The author observed maximum bite force, slope of bite force graph, curve index and
duration of maximal bite force by way of the foil strain gauge (MPM -3,000) and RS
Dymograph (Beck-man).
The obtained results were as follows;
1. Maximal bite forces were 15.18§¸ of the normals and 5.41§¸ of the experimentals.
2. The slopes of bite force graph were 61.09¡Æ of the normals and 50.68¡Æ of the
experimentals.
3. The curve indexes were 0.74 of the normals and 2.05 of the experimentals.
4. The duration of maximal bite force were.0.22 sec of the normals and 0.27 sec of
the experimentals.
