摘要： The present invention provides a dental curable composition comprising (A) a polymerizable monomer, (B) an inorganic filler, and (C) a polymerization initiator,

wherein the polymerizable monomer (A) comprises (a1) a polyfunctional (meth)acrylate monomer comprising urethane bonds, (a2) a polyfunctional (meth)acrylate monomer comprising hydroxyl groups, and (a3) a polyfunctional (meth)acrylate monomer comprising carboxyl groups,
the ratio by weight of (a1):(a2)+(a3) ranges from 1:1 to 9:1, the number of hydroxyl groups is not more than 0.5 relative to the number of (meth)acryloyl groups in one molecule of the above-mentioned (a2), and the number of carboxyl groups is not more than 0.5 relative to the number of (meth)acryloyl groups in one molecule of the above-mentioned (a3).

摘要： Provided are opaque materials exhibiting a good adhesive strength and a good color tone reproduction comparable with natural dental crowns as well as having a good operability. In addition, the opaque materials may exhibit a stain-resistance property in rebuilding-up a dental composition on the opaque materials in a cured form with a metal instrument. Further, the opaque materials may exhibit a good color tone reproduction comparable with natural dental crowns even if a dental membrane is thinly formed from the opaque metals. The dental membrane is formed from a first opaque layer and a second opaque layer, wherein the first opaque layer contains a filler of indefinite-shape particles and the second opaque layer contains a filler of spherical-shape particles, and wherein the first opaque layer is formed on a metal base and the second opaque layer is formed on the first opaque layer.
