Flexural Strength and Degree of Polymerization of a Proprietary Denture Base Acrylic Resin Designed to be Cured using Long or Short Cycles

Abstract - The flexural strength and degree of polymerization of Diamond D acrylic resin prepared with a long cure monomer and a short cure monomer were investigated using Trevalon as a control. Flexural strength and degree of polymerization of Diamond D acrylic resin were not affected by either using a long cure monomer or the short cure monomer. There was no significant difference in the glass transition temperature Tg between the long and slow cure Diamond D. Provided the manufacturer’s instructions are followed the flexural strength, degree of polymerization and glass transition temperature are comparable with more traditional products.
