Effect of physical strength of luting cements on zirconia fixation

Abstract

RMGICs (Resin-Modified Glass Ionomer Cements) have been commonly used as the luting cement. Along with the development of high strength ceramics such as alumina or zirconia, the luting cement with stronger property is greatly desired. In order to increase the physical strength of luting cement, copolymerizable acid monomers are adopted that can react with structure-forming neutral monomers. Copolymerization among monomers can fortify the cement matrix in addition to ionic bond between acid monomers and glass fillers. In this study, the effect of luting cement strength on zirconia fixing is evaluated.
