Abstract

In case of fixed partial denture cases, how to set the contact state between the applied pontic basal surface of fixed partial denture and the alveolar mucosa is important. Various opinions are presented including slight and noncompression methods. How to confirm the contact state in the mouse depends on the doctor's experience and no established method is available. In determination of the contact pressure between the pontic basal surface and alveolar mucosa, a polyvinylidene fluoride film (PVDF) is continuously used.<BR>In the present study, similar to Report 1, PVDF, previously bonded to pseudomucosa, was tested under various compression conditions using a pressure tool, which simulated the pontic basal surface, to analyze the amount of load in relation to the output voltage of PVDF. The results were as follows:<BR>1. A high correlation was observed between the amount of load added and the output voltage of PVDF irrespective of the pressure condition.<BR>2. By measuring the area surrounded by the PVDF output voltage line and zero-voltage line, it was possible to presume the amount of dynamic load applied to the pseudomucosa.<BR>The results suggested that PVDF can be successfully applied to adjust the pontic basal surface of a fixed partial denture.
