Ceramic material substructure for a dental restoration of this ceramic material and dental restoration.

摘要

The present invention relates to a method for producing a ceramic material, subsequently comprising mixing ceramic material, such as oxidic ceramic material, which as a raw material essentially comprises aluminum oxide, zirconium oxide and/or titanium oxide, and glass component; melting at least the glass component in the mixture by sintering, where the glass component infiltrates the ceramic material and absorbs raw material of the ceramic material through a reaction at the surface; and bringing the mixture into a shape, such as powder, which is suitable for further processing, such as additional sintering. Also the present invention relates to a basis for the crown, the crown in its entirety having layers of for instance porcelain applied to the basis, and methods for producing the basis and the crown through subsequent processing steps, to which the basis is preferably subjected on the same underground, for instance based on CAD/CAM techniques.
