ABSTRACT:
The invention relates to compositions based on ZrO2, and single- and multi-colored blanks made from oxide ceramics, and a process for their preparation, in which oxide ceramic powder is coated with a coloring substance, the coated powders are preferably graded and at least one colored powder is filled into a compression mould, the colored powder or powders are compressed to produce a shaped body, and the compressed shaped body is sintered to produce a blank, and to the use of these blanks for the preparation of dental restorations.
