| 摘要 |
A dental restorative material is disclosed, comprising an amorphous inorganic material having a refractive index in a D-line of sodium in the range of 1.470~1.520 and having an X-ray opacity; a (meth)acrylic ester monomer not having a benzene ring in a molecule thereof; and a polymerization initiator, if desired, the dental restorative material according to the invention further comprises an amorphous inorganic material having a refractive index in a D-line of sodium equal to or less than that of the (meth)acrylic ester monomer not having a benzene ring in a molecule thereof, the dental restorative material of the invention has an X-ray opacity and translucency close to natural teeth, and has superior esthetics not using a monomer having a benzene ring which has a fear of an environmental hormone action.
