Abstract
The invention relates to a dental application body, comprising an oxide ceramic, containing a bulk material containing an oxide ceramic, preferably a zirconium oxide, and at least one coating containing an yttrium oxide and/or cerium oxide stabilized zirconium oxide, wherein the content of the stabilizing compound (c, C) within the coating with respect to the zirconium oxide (in mol-%) satisfies the formula c+0.6×c≧4. Furthermore, the invention relates to a method for producing such a dental application body comprising the steps of providing a bulk material containing an oxide ceramic, preferably a zirconium oxide having a tetragonal microstructure as a main phase, and applying at least one coating containing an yttrium oxide and/or cerium oxide stabilized zirconium oxide, wherein the content of the stabilizing compound (C, C) within the coating with respect to the zirconium oxide (in mol-%) satisfies the formula c+0.6 ×c≧4.
