    摘要： A dental composition comprising a polymerizable monomer (1), initiator, filler component(s) in an amount of more than about 20 wt.-%, wt.-% with respect to the whole weight of the composition, the polymerizable monomer (1) being characterized as follows: having exactly two (meth)acrylate reactive moieties, having an unsymmetrical backbone as linkage between the (meth)acrylate reactive moieties, the two (meth)acrylate reactive moieties being attached onto the unsymmetrical monomer backbone as alkyl esters, the unsymmetrical backbone comprising one aromatic moiety of the phenolic type, the polymerizable monomer (1) not containing an acidic moiety, other atoms than carbon, hydrogen, nitrogen, and oxygen, a bisphenol moiety. The invention is also directed to the use of the dental composition as or for producing a dental filling material, dental cement, crown and bridge material, inlay, onlay, veneer, orthodontic device or dental mill blank.

    摘要： The present application 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 application 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).
