Abstract
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).
