Estimating the term…
The invention relates to a single- or multi-unit dental restoration, which consists of a support structure and a veneer, which support structure is in particular made from oxide ceramics by means of additive manufacturing, particularly preferably by means of rapid prototyping, wherein the veneer is produced by pressing a ceramic material, such as a glass ceramic or composite material, which is more translucent than the support structure, characterized in that the veneer fills and/or penetrates recesses of the support structure (12) configured as a net or frame structure or as a reinforcement, wherein it is particularly provided that the recesses penetrate through the support structure (12).

A dental restoration which comprises
A method of producing a single- or multi-unit dental restoration, in which a veneer is produced by CAD design in such a manner that the CAD software initially constructs a support structure which is made from oxide or glass ceramic materials by additive manufacturing, and that the veneer is produced by means of muffle presses, from a glass ceramic material, which is more translucent than the oxide ceramic material, characterized in that the CAD software determines the boundary surfaces between the ceramic support (12) and the veneer such that the ceramic support (12) is configured in a net, honeycomb or frame structure by forming recesses which are filled by the veneer glass ceramic material.
