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).
