Document Type and Number:
WIPO Patent Application WO/2022/145479
Kind Code:
A1
Abstract:
The present invention provides a curable composition for dental restoration which gives cured objects that have high mechanical strength and toughness and are excellent in terms of water resistance and gloss retention, a dental composite resin comprising the curable composition for dental restoration, and a dental mill blank comprising a cured object formed from the curable composition for dental restoration. The present invention relates to a curable composition for dental restoration comprising: a (meth)acrylic acid ester compound (A) which has at least one polymer structure selected from the group consisting of polycarbonates, polyarylates, and aromatic polysulfones and in which a terminal hydroxy residue derived from a repeating unit serving as a component of the polymer structure has been directly (meth)acryloylated; a (meth)acrylic acid ester compound (B) having two or more (meth)acryloyloxy groups (the compound (B) is not the (meth)acrylic acid ester compound (A)); an inorganic filler (C) having an average primary-particle diameter of 0.01-5 μm; and a polymerization initiator (D).
