摘要： An embodiment of the invention is a method for automatic calibration of dental furnaces, there is made available a dental furnace comprising a control unit adapted to control the dental furnace for performing a firing process defined by firing process parameters such as e.g. the temperature and/or a temporal temperature curve and/or a temperature gradient and/or a vacuum in a firing chamber of the dental furnace. There is provided at least one calibration firing-object sample made of a dental material, where said dental material, after said calibration firing-object sample has been subjected to a calibration firing-object process with predetermined firing process parameters, has a defined desired color stored e.g. in the control unit. Further, a color measuring device is used which, for transmission of measurement signals and/or measurement results, is operatively connected to the control unit.

摘要： Disclosed is a heating element for a dental furnace including a tube element for accommodating a heating coil inside the tube element. At least one closing element may be connected to at least one open end of the tube element, wherein electrical connectors may be led through the closing element and fused with the element. The tube element may be made from a ceramic material, such as oxide ceramics, that may be connected to the connector via a plurality of intermediate glasses/transition glasses and glass solder to compensate for different heat expansion coefficients such that up to 500° C. gas escaping from the tube element may not enter due to a thermal action, providing that operational safety of the heating element is ensured. Further, disclosed is a dental furnace including such a heating element.
