Abstract
(EN)
The invention relates to a method (100) and to a corresponding system (1) for providing a dental prosthesis (10) made from ceramic material (2) having a colour matched to the patient comprising the following steps: - receiving (110) a desired nominal colour for the dental prosthesis (10), determining (120) a deviation between the nominal colour and actual colour of the sintered ceramic material (2) by the control unit (4) and defining (130) a temperature time cycle havoing a cycle time (TH), suitable for compensation of the deviation, for sintering at a defined sintering temperature (TS) and creating a corresponding sintering program (5) by the control unit (4); and - adjusting (140) the actual colour of the selected ceramic material (2) to the nominal colour (4) in the sintering furnace (3) by the sintering program (5) executed by the sintering furnace (3).
