抄録

In order to develop a measurement system for the additional load by contacting the basal surface of the pontic, polyvinylidene fluoride film (PVDF) was used to investigate its usefulness.
The following four parameters correlated with additional loads:
(1) maximum of positive output voltage, (2) maximum of negative output voltage, (3) first area surrounded with non-output line and output voltage line, and (4) entire area surrounded by non-output line and output voltage line.
Additional loads were computed by these parameters.
The result indicates that PVDF is useful for measuring the load added by contacting the basal surface of the pontic.
