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).

Abstract: A paste-type dental material is filled from an opening portion of a cartridge into a cylindrical portion by moving the opening portion of the cylindrical portion of the cartridge along a kneading surface, on which the paste-type dental material is kneaded, with the opening portion being inclined. The piston is placed on the kneading surface with a circular end surface of the piston contacting the kneading surface. The piston is inserted into the cylindrical portion by moving the opening portion of the cylindrical portion of the cartridge closer to the piston located on the kneading surface such that a piston-side tapered surface or the piston-side curved surface of the piston is fitted into the opening portion, and thereafter moving the one of the two ends of the cylindrical portion toward the kneading surface.
