Abstract

We had prepared an effective monomer, 4-META, to promote adhesion to dental hard tissues and studied several adhesives based on the methacrylate.A new type adhesive resin cement was reported previously.It consisted of an adhesive liner containing 4-META, MMA as a liquid and TMPT filler, reactive microfilled composite filler, as a powder.Here, an adhesive liner was improved by addition of a silane coupling agent into the previous liner.The new liner gave good adhesion to porcelain as could be expected.The adhesive strengths were as good as 120kgf/cm2 to etched enamel, 45kgf/cm2 to etched dentin, 110-180kgf/cm2 to sandblasted dental alloys including a type I Gold alloy and 100-160kgf/cm2 to porcelains.
