Curable composition for dental restoration

Abstract

The present invention provides a dental restorative curable composition that has high mechanical strength and toughness and has excellent water resistance and smoothness/gloss durability in the form of a cured product, a dental composite resin comprising the dental restorative curable composition, and a dental mill blank comprising a cured product of the dental restorative curable composition. The present invention relates to a dental restorative curable composition comprising: a (meth)acrylic acid ester compound (A) which has at least one polymer structure selected from the group consisting of a polycarbonate, a polyarylate, and an aromatic polysulfone and in which terminal hydroxy residues derived from repeating units constituting the polymer structure are directly (meth)acryloylated; a (meth)acrylic acid ester compound (B) having two or more (meth)acryloyloxy groups (excluding the (meth)acrylic acid ester compound (A)); an inorganic filler (C) having an average primary particle diameter of 0.01 to 5 μm; and a polymerization initiator (D).
