A method for producing a dental restoration (D) by CAD casting is described, said method comprising the steps of a) recording three-dimensional, digital data of the dentition or of a part of the dentition of a patient, b) creating a virtual dental restoration (VD) using the recorded three-dimensional, digital data, wherein the virtual dental restoration (VD) is expanded in relation to the dental restoration (D) to be produced, c) preparing a model (M) using the created virtual dental restoration, such that the model (M) is expanded in relation to the dental restoration (D) to be produced, d) embedding the model (M) in an embedding compound (EM), e) hardening the embedding compound (EM) and removing the model (M), such that a casting mold is obtained, f) filling the casting mold, preferably by pouring, with a casting material (GM) and cooling the casting material (GM), such that the dental restoration (D) is obtained, and optionally the further steps of g) working the dental restoration (D), and h) veneering the dental restoration (D). A novel embedding compound (EM) is also described that has no expansion or at least is only a slight expansion on setting.

The present invention relates to a method of producing a (shaped) ceramic or glass-ceramic article, involving the steps of: (a) providing a powder or a powder mixture comprising ceramic or glass-ceramic material, (b) depositing a layer of said powder or powder mixture on a surface, (d) heating at least one region of said layer by means of an energy beam or a plurality of energy beams to a maximum temperature such that at least a part of said ceramic or glass-ceramic material in said at least one region is melted and (e) cooling said at least one region of said layer so that at least part of the material melted in step (d) is solidified, such that the layer is joined with said surface in said at least one region. The invention also relates to ceramic or glass-ceramic articles and their use.
