Abstract: A dental curable composition capable of use as a dental material that can substitute part or all of a natural tooth, in particular, a resin material for dental cutting and machining in the field of dental care. When a block shape usable as the resin material is produced, while mechanical properties and aesthetic properties required for a crown prosthetic appliance are maintained, the dental curable composition can be molded and processed with pressure and heating while strain generated in the block is reduced and no cracks and chipping occur. The dental curable composition includes (a) a polymerizable monomer and (b) a filler in a weight ratio of 10:90 to 70:30, and 0.01 to 10 parts by weight of (c) a polymerization initiator and 0.001 to 1 part by weight of (d) a chain transfer agent being a terpenoid compound based on 100 parts by weight of the polymerizable monomer (a).

Abstract: The present invention relates to a dental curable composition that can be suitably used as a dental material that can substitute part or all of a natural tooth, in particular, a resin material for dental cutting and machining in the field of dental care. An object of the present invention is to provide a dental curable composition in which, when a block shape usable as a resin material for dental cutting and machining is produced while mechanical properties such as hardness, bending strength and compressive strength as well as aesthetic property required for a crown prosthetic appliance are maintained, the dental curable composition can be molded and processed with pressure and heating while strain generated in the block is reduced and no cracks and chipping occur. There is provided a dental curable composition including (a) a polymerizable monomer and (b) a filler in a weight ratio of 10:90 to 70:30, and including 0.01 to 10 parts by weight of (c) a polymerization initiator and 0.001 to 1 part by weight of (d) a chain transfer agent being a terpenoid compound based on 100 parts by weight of the polymerizable monomer (a).
