The purpose of this study was to examine the physical properties of newly-developed Polycarbonate resin for denture base (Developmental code No.: SI-9301, Shofu Co.) and compare the properties with those of heat curing acrylic resin.
The results were as follows:
Bending rigidity, tensile strength and superficial hardness of the polycarbonate resin were not superior to those of heat curing acrylic resin.
However, water repellence, water insolubility, abrasionproof power and bending strength of the ploycarbonate resin were superior to those of heat curing acrylic resin.
Investigating these results from the stand point of physical properties clinically required for the denture base material, it was revealed that the physical properties of polycarbonate resin examined in this study are superior to those of heat curing acrylic resin.
