Claim 0:
1. A method for providing a dental prosthesis for a patient which is made from a ceramic material having a colour matched to a patient situation, wherein a sintering furnace for sintering the ceramic material and a control unit ELIA] for controlling the sintering furnace are used for carrying out the following steps:
receiving a desired nominal colour for the dental prosthesis by the control unit;
determining a deviation between the nominal colour and actual colour of the sintered ceramic material by the control unit;
defining a temperature-time cycle, suitable for compensation of the deviation, for sintering at a defined sintering temperature and creating a corresponding sintering program having a cycle time individually defined for the ceramic material to be sintered by the control unit; and
adjusting the actual colour of the ceramic material to the nominal colour in the sintering furnace by the sintering program created by the control unit and executed by the sintering furnace.
