Claim 10:
11. A system for providing a dental prosthesis for a patient which is made from a ceramic material having a colour matched to a patient situation by means of a sintering furnace for sintering the ceramic material and a control unit which is connected to the sintering furnace via a data line for controlling the sintering furnace and is designed to:
receive a desired nominal colour for the dental prosthesis,
determine a deviation between the nominal colour and the actual colour,
define a temperature-time cycle having a cycle time, suitable for compensation of the deviation, for sintering at a defined sintering temperature and
create a corresponding sintering program having a cycle time individually defined for the ceramic material to be sintered,
wherein the sintering furnace is provided to execute a corresponding sintering program called up by the control unit which comprises the defined cycle time at the defined sintering temperature and so adjust the actual colour of the selected ceramic material to the nominal colour.
