  • Patent number: 9603683
    Abstract: 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 t

  • Patent number: 8636512
    Abstract: A set of elements is described for use in the production of a dental prosthesis (20), in particular of a crown, a bridge, an inlay or an onlay, comprising: a framework (3) and one or more model parts (5) for defining parts of the outer contour of a veneer (15) for the framework (3), wherein the model part or parts (5) can be mounted on the framework (3) in such a way that, at one and the same time, (i) a gap (7) remains between the model part or parts (5) and the framework (3) and (ii) the model part or parts (5) define parts [lacuna] the outer contour. Corresponding methods and systems are also described.

  • Publication number: 20120148987
    Abstract: In a method for forming a dental part, a laser beam is guided over a powder layer of biocompatible material. The laser is guided by a computer controlled laser scanning system based on data representing the shape of the cross-section through the shaped body. The powder is substantially melted by the laser beam to form a layer in the shaped body, to build the shaped body entirely from layers of laser-melted material.

  • Publication number: 20090189315
    Abstract: The invention relates, inter alia, to a method for the production of a ceramic shaped body (22), comprising the following steps: production or provision of a green body (10) having a structured surface region (12), irradiation of at least the structured surface region (12), so that the green body (10) is consolidated in the region of a volume zone (16) including the structured surface region (12), but is not consolidated or is consolidated to only a lesser degree in volume zones further from the surface, separation of the consolidated volume zone (16) including the structured surface region (12) from parts of the green body (10) which have not been consolidated or have been consolidated to only a lesser degree, and optionally scouring of the consolidated volume zone (16) obtained in this way.
