Abstract

A dental furnace having a display device and an operating device ( 10 ) for the dental furnace, is provided, the operating device being integrated in particular in the display device by forming a touch screen ( 12 ), and the operating device ( 10 ) facilitating the selection of programs for the firing of dental restoration parts in the dental furnace. The operating device ( 10 ) allows in particular the input of further parameters for a firing cycle. An operating element ( 30, 32, 34 ) facilitates the control of a final firing program of the dental furnace, namely with different values for the temperature as well as for the duration of the final firing, the operating element ( 30, 32, 34 ) making possible the simultaneous adjusting of temperature and duration parameters of the final firing.

First claim

The invention claimed is:

1. A dental furnace comprising
a display device and
an operating device,
wherein the operating device is integrated in the display device by forming a touch screen,
wherein the operating device facilitates the selection of programs for the firing of dental restoration parts in the dental furnace,
wherein the operating device allows the input of further parameters for a firing cycle,
wherein an operating element facilitates the control of a final firing program of the dental furnace, with different values for the temperature as well as for the duration of the final firing,
the operating element causing the simultaneous adjusting of temperature and duration of time parameters of the final firing,
wherein the operating element is connected to a control device for the final firing program, and
wherein the control device adjusts the temperature and duration of the final firing and increases the duration as the temperature increases.

2. The dental furnace according to claim 1 , wherein a control device of the dental furnace allows the activation of a final firing program with a plurality of values for temperature and duration of the final firing, wherein the temperature as well as the duration of the final firing are increased with increased values and reduced with reduced values.

3. The dental furnace according to claim 1 , wherein a control device for the dental furnace responding to the operating element for controlling the final firing program comprises a preset mode in which a temperature and a duration are preset for a predefined final firing value, and wherein the temperature and duration consistently increase without oscillating with increasing final firing values.

4. The dental furnace according to claim 1 , wherein the operating panel comprises a slide control function by which the intensity of the final firing is adjustable, and wherein a predefined final firing value of the slide control is adjustable by an operator.

5. The dental furnace according to claim 1 , wherein the display device is integrated in the operating device of the dental furnace in the form of a touch screen and comprises a key function which activates a final firing program and which displays an adjustable final firing control on the display device.

6. The dental furnace according to claim 5 , wherein the operating panel of the final firing program offers at least 2 values for adjusting the final firing program which each comprise predefined and allocated settings for the temperature and duration of the final firing.

7. The dental furnace according to claim 1 , wherein temperature/time value pairs are preset for the final firing and provide a plurality of value pairs to the user for adjusting the final firing.

8. The dental furnace of claim 1 wherein the operating element comprises an operating panel.

9. The dental furnace according to claim 8 , wherein by activation of the operating panel for controlling a final firing program the display of the display device is changed in such a way that the parameter values of the final firing are adjustable.

10. The dental furnace according to claim 9 , wherein in a final firing mode a remaining selection of programs for firing dental restoration parts is blocked.

11. The dental furnace according to claim 8 , wherein the operating panel of the final firing program offers at least 3 values for adjusting the final firing program which each comprise predefined and allocated settings for the temperature and duration of the final firing.

12. The dental furnace according to claim 1 , wherein temperature/time value pairs are preset for the final firing and provide 3 to 10 value pairs to the user for adjusting the final firing.

13. A method of operating a dental furnace, in which the temperature and/or the selected program for the operation of the firing of dental restoration parts is set up on a display device, and wherein an operating device is used to adjust the program and/or further parameters of the dental furnace, comprising:
firing dental restoration parts,
wherein after the firing of the dental restoration parts a final firing program of the dental furnace is selected via an operating element, and
wherein one additional value from a predefined value pair comprising temperature and duration of the final firing is selected by which the temperature and the duration parameters of the final firing are adjusted simultaneously,
wherein the temperature and duration of the final firing are adjusted such that the duration increases as the temperature increases.
