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.

Abstract: A dental restorative curable compositions may have a high mechanical strength and excellent water resistance and polishability in the form of a cured product. A dental composite resin may include such compositions. A dental mill blank may include the cured product of such compositions. A dental restorative curable composition may include: a (meth)acrylic acid ester compound (A) having two or more (meth)acryloyloxy groups per molecule; a mono(meth)acrylic acid ester compound (B); an inorganic filler (C) having an average primary particle diameter of 0.01 to 5 ?m; and a polymerization initiator (D).
