Abstract:
Shaded, zirconia ceramic materials are disclosed that are suitable for use in dental applications. Ceramic bodies are made from a zirconia-containing ceramic material and a coloring composition comprising a terbium (Tb)-containing component and a chromium (Cr)-containing component as a coloring agent. The pre-shaded ceramic body is machinable into a dental restoration either as a bisque body or sintered body. A pre-shaded machinable sintered ceramic body may obviate the need for further processing steps, such as shading or sintering, and may be suitable for use in chair-side machining applications, such as in a dentist's office, significantly reducing the time to create a custom finished product.

Claim (Index 13):
A ceramic powder suitable for use in dental restoration applications that comprises\n a. a ceramic material comprising an yttria-stabilized zirconia that comprises from 2 mol % to 7 mol % yttria, and b. a coloring agent comprising 0.002 mass % to 0.65 mass % Tb and Cr combined, measured as metal ions,\n wherein a mass ratio of Tb ions to Cr ions is in a range of approximately 93:7 Tb:Cr to 99.5:0.5 Tb:Cr, and \n c. optionally, a binder.
