    摘要： A method for producing a cold casting mold (100) for producing dental molded parts (210) from a mixing compound (200), wherein the cold casting mold (100), having a cavity (110) that corresponds geometrically to the dental molded part (210), is additively constructed from a starting material (150) by means of a 3D printing method on the basis of a digital data set based on a three-dimensional model of the oral cavity of a patient and at least one first opening (111) that opens into the cavity (110) for filling with the mixing compound (200). The invention also relates to such an additively constructed cold casting mold (100) for a method for producing dental molded parts (210) from a sinterable or a light-curing mixing compound (200). The cold casting mold (100) is constructed having at least one second opening that opens into the cavity (110) for discharging gases and/or liquids.

    摘要： A method for producing molded parts from a sinterable mixing compound using a cold casting mold having a cavity that corresponds geometrically to the molded part and at least one opening into the cavity, wherein the mold is additively constructed from a starting material, in particular a 3D printing method using a 3D printer, and wherein the cavity is created on the basis of a digital data set, in particular based on a three-dimensional model of the oral cavity of a patient. The cavity is filled via the opening with the sinterable mixing compound, curing and/or solidifying the mixing compound, wherein gases and/or liquids contained in the mixing compound are discharged from the cavity via the opening, thermally and/or thermochemically decomposing the mold at a temperature from 200° C. to 2500° C. and sintering the mixing compound to hardness at a temperature from 900° C. to 2500° C. until a molded part is obtained.

    摘要： A method for producing an implant blank (100), in particular a dental implant blank from a starting body, said implant blank (100) comprising at least one first area, which is a surface area (102), and a second area, which is a core area (101), wherein the surface area (102) has at least one bioactive surface material (502) and extends from at least one first surface (103) in the direction of the core area (101), and the core area (101) has at least one carrier material that can be subjected to mechanical load. The starting body has a porosity for controlling a targeted distribution of the bioactive surface material (502) within the starting body and is loaded with a solution (500) of the bioactive surface material (502) in a first step, which is a loading step. In a second step, which is a distribution control step, the distribution of the bioactive surface material (502) within the starting body is controlled such that the solution (500) has a higher concentration within the surface area (102) than within the core area (101), the control being effected by regulating one or more environmental parameters in a closed environment (200), in particular by regulating the humidity and/or the pressure and/or the temperature.
