1. A dental curable composition for a resin material for dental cutting and machining comprising:
(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 0.1 to 0.5 part by weight of (d) a chain transfer agent being a terpenoid compound based on 100 parts by weight of the polymerizable monomer (a),
wherein the polymerization initiator (c) consists of a thermal polymerization initiator,
wherein an average particle size of the filler (b) is in a range from 0.5 to 100 μm,
wherein the filler (b) consists of a member selected from the group consisting of an inorganic filler, a polyvinyl acetate, a polyethylene glycol, a polypropylene glycol, a polyvinyl alcohol, and combinations thereof, and
wherein the dental curable composition is:
a two part dental curable composition wherein neither of the two parts is a powder component containing the polymerization initiator (c).
