Abstract
It has been reported that the polymerization time of acrylic resins is reduced considerably by application of microwave energy to the FRP dental flask during denture processing. However, a superior quality denture may not be obtained when conventional heat curing resins are used with this microwave polymerization process.
We have developed a new acrylic denture resin for use especially with microwave polymerization. We found no problems with denture porosity or heterogeneous polymerization when this microwave resin was used in place of conventional ones. Microwave irradiaton also makes possible a very short curing time of only three minutes and produces an excellent polymer.
The denture fabricated using this process has superior adaptability and the bond strength with resin teeth exceeded our expectations. It is thus possible to make a denture in a very short time using the microwave curing technique. This is considered a very useful technique.
