Abstract
The present invention relates to a method of manufacturing a dental component, in particular a dental prosthesis or a partial dental prosthesis, by means of a dental furnace, comprising the following steps: (i) additively manufacturing, in particular by means of 3D printing, a model of the dental component from a model material on the basis of a virtual 3D model of the dental component; (ii) embedding the model in an investment material; (iii) removing the model from the investment material, in particular by heating or burning out, to obtain a negative mold of the model; (iv) inserting a raw material required for manufacturing the dental component into the negative mold; (v) producing the dental component in the negative mold; and (vi) removing the negative mold.
Claims14
A method of manufacturing a dental component, the method comprising the following steps:
- (i) additively manufacturing a physical structure including a model of the dental component from a model material on the basis of a virtual model of the dental component, the physical structure including a base body integrally connected to the model via a connection passage;
- (ii) embedding the physical structure in an investment material;
- (iii) removing the physical structure from the investment material to obtain a negative mold of the model, the connection passage, and the base body;
- (iv) inserting a raw material for manufacturing the dental component into the negative mold;
- (v) producing the dental component from the raw material in the negative mold;
- and
- (vi) removing the negative mold from the dental component;
- wherein the physical structure is positioned on a base plate integrally produced with the physical structure by means of the additive manufacturing process;
- and
- wherein at least one section of an embedding housing part provided for embedding the physical structure in the investment material is integrally produced with the base plate by means of the additive manufacturing process.
