| abstract |
The present invention relates to a multilayer oxide ceramic body comprising at least two different layers and suitable for dental applications, in particular a pre-sintered multilayer oxide ceramic blank and an oxide ceramic green body, wherein at least one layer comprises Containing La 2 O 3 , the at least two different layers differ in their La 2 O 3 content. These objects can be thermally densified by further sintering without distortion and are therefore particularly suitable for the production of dental restorations. The invention also relates to a process for producing such a multilayer oxide ceramic body, as well as a process for producing a dental restoration using said multilayer oxide ceramic body. |
