Abstract:
A method for enhancing optical properties of sintered, zirconia ceramic bodies and zirconia ceramic dental restorations is provided. The porous or pre-sintered stage of a ceramic body is treated with an yttrium-containing composition and sintered, resulting in sintered ceramic bodies having enhanced optical properties. The enhanced optical properties may be substantially permanent, remaining for the useful life of the sintered ceramic body.

Claim (Index 1):
Method for enhancing the translucency of a sintered zirconia dental restoration comprising\n obtaining a porous zirconia ceramic body that comprises an yttria-stabilized zirconia material comprising 2 mol % yttria to 7 mol % yttria; obtaining an aqueous yttrium-containing composition comprising\n between 20% wt and 70% wt yttrium-containing material and \n a colorant comprising at least one metal-containing component as a coloring agent; and \n providing a first application of the yttrium-containing composition to penetrate a portion of the porous zirconia ceramic body; and providing a second application of the yttrium-containing composition to penetrate the portion of the porous zirconia ceramic body that comprises the aqueous yttrium-containing composition of the first application.
