Light Curing Soft Denture Liner Using Liquid Fluoropolymer : Part II.Effect of Cross-Linking Agents

Abstract

We prepared and evaluated new experimental soft denture lining materials composed of fluoropolymer(vinylidene fluoride/hexafluoropropylene copolymer)and methyl methacrylate(MMA)by modifying three kinds of cross-linking agents.Sorption of water or oil, hardness, water contact angle, elution of MMA, and viscoelastic property were measured.By the addition of cross-linking agents, water sorption, hardness, and viscosity decreased, but the values of water contact angle, and the amount of MMA eluted remained almost unchanged.Oil sorption decreased with time, suggesting the need for further research and improvement.
