Abstract
In this study we compared the results of the superficial Rockwell hardness test and the transverse strength test of 6 denture base resins by curing all these specimens with microwave.The following results were obtained from these tests:1. Concerning heat curing resin, hardness of the most outer surface did not change between microwave curing and heat curing. However hardness of polished surface decreased. As to flexure strength there was no significant difference between the result of microwave curing and heat curing, but modulus of elasticity decreased.2. Concerning self-curing resin, the type in which the size of powder polymers is reduced to increase its flow revealed the decrease of surface hardness by microwave curing comparing with the result of curing designated by the manufacturer. The flexure test showed no significant difference or some increase of flexure strength and modulus of elasticity by microwave curing comparing with curing designated by the manufacturer.3. When each type of resin is cured by microwaves, hardness of polished surface decreases. However strength is assumed to increase by increased generation of internal heat due to increase of monomers during irradiation of microwaves.
