Method for automatic calibration of dental furnaces and dental furnace with automatic calibration

The automatic calibration method involves providing a color measuring device (18) that is operatively connected to a control unit (14) for transmission of measurement signals. A target/actual comparison is performed between a defined desired color and the metrologically detected actual color of fire...

More Information
Summary:The automatic calibration method involves providing a color measuring device (18) that is operatively connected to a control unit (14) for transmission of measurement signals. A target/actual comparison is performed between a defined desired color and the metrologically detected actual color of fired dental material of a calibration firing-object sample (16). The firing process parameters are calibrated and stored for use under control of the control unit. An automatically readable table contains different values for firing process parameter and values of actual colors assigned to the values.
