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. |
