Embodiment Construction

[0049] figure 1 The dental furnace 10 shown in includes a furnace hood 12 as a furnace upper part, and a furnace bottom part 14 . The dental furnace is configured as a muffle pressure furnace and the annular furnace hood 12 internally forms a firing chamber in a manner known per se, the diameter of which is also sufficient to accommodate a similarly annular and substantially cylindrical muffle.

[0050] The furnace floor portion includes an inclined plane 16 supporting a touch sensitive display 18 by which the inventive dental furnace 10 can be actuated.

[0051] The furnace hood 12 is supported on the furnace floor part 14 by lifting / pivoting means in a manner known per se, so that the furnace hood 12 can be lifted off the furnace bottom part and swiveled open by leaving a gap. Also in a manner known per se, the furnace can perform combustion by switching on the heating elements in the furnace hood when the furnace hood is closed and by inserting a pressing stamp or plunger ...

Abstract

A dental furnace (10) for dental restorations comprising a firing chamber into which, in particular between a furnace bottom part (14) and a furnace upper part (12), the dental restoration, in particular within a muffle, can be introduced, and a sensor that is connected with a control device (52) for the dental furnace (10), wherein the sensor, in particular the temperature sensor (22), is arranged outside the firing chamber and comprises a detection range (40) that also extends outside the firing chamber.

Description

technical field [0001] The invention relates to a dental furnace for dental restorations according to the preamble of claim 1 . Background technique [0002] Dental furnaces with temperature control have been known for a long time. [0003] Thus, for example in DE 1 160 777 dental furnaces have been provided for maintaining a constant temperature in the muffle. Such a muffle furnace is used for firing dental restoration parts in a furnace, the muffle furnace comprising a negative mold of the dental restoration part to be obtained. In the illustrated solution, a preheating chamber is provided below the actual firing chamber and the thermal power of the local firing chamber heating is controlled or driven by a DC transformer. So-called chopper controllers, which can be considered a precursor to PID controllers, control heat. [0004] If short cycle times and an ergonomically optimized workflow have to be provided for dental restoration parts, the solutions described in the ...
