Patent ID: 11774175

Abstract:
The invention relates to a dental furnace, in particular a high-temperature dental furnace for oxide ceramics such as zirconium dioxide with sintering temperatures of between 1350° C. and 1650° C., having heating elements (14, 16) which are intended to give off heating energy to a firing chamber (12) in the dental furnace (10). The heating elements (14, 16) are configured as electrical resistance heating elements and supported below the firing chamber (12) each by means of at least one heating element support foot (18). The heating elements (14, 16) extend vertically to the top starting from the heating element support feet (18) and at the top, end in an arch (46), in particular in a semicircular arch or possibly in a pointed arch, without an upper lateral support, in particular not in the region of the arch (46).
