POWDER-LIQUID TYPE RESIN-REINFORCED DENTAL GLASS IONOMER CEMENT COMPOSITION

摘要

The present invention exhibits high surface hardenability even under wet conditions, whereby it is difficult to cause surface turbidity even when moisture comes in contact with it at the beginning of hardening, and the cured product exhibits high mechanical properties while exhibiting little absorption expansion and excellent color resistance. Provides a dental resin reinforced glass ionomer cement composition having excellent storage stability. (a) a bonsai containing acid-reactive glass powder, (b) water, a polymer of (c) an acidic group-containing polymerizable monomer, (d) a (meth)acrylate-based polymerizable monomer having a hydroxyl group, and (e) Consisting of a liquid material containing a trifunctional or higher (meth)acrylamide polymerizable monomer, (f) a polymerization initiator is contained in at least one of the bonsai and the liquid material, and optionally in at least one of the bonsai and the liquid material (g) It provides a dental resin-reinforced glass ionomer cement composition containing an acidic group-containing polymerizable monomer.
