Abstract
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.
