Certain embodiments of the invention relate to a method of manufacturing a dental bridge. In certain embodiments of the method, a pre-sintered blank made from a green body of ceramic material is subjected to a machining operation that transforms the blank into an intermediate product with a bridge structure and a support body linked to the bridge structure by one or several retaining sections that extend from the support body to the bridge structure. In certain embodiments, a sintering operation is then performed on the intermediate product while the retaining section(s) still link(s) the support body to the bridge structure.

Method and arrangement for forming a dental bridge

Methods of producing a dental product are disclosed. Certain methods include the steps of providing a pre-sintered blank made from a green body of ceramic material, performing a machining operation on the blank, and subsequently sintering the blank to its final density in a sintering operation performed at a temperature in the range of 1300&#xb0; C. to 1650&#xb0; C. The pre-sintered blank that is provided may have a strength in the range of 53-107 MPa.

Method of producing a dental product

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&#xd7;c&#x2267;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 &#xd7;c&#x2267;4.
