Abstract
The invention relates to a dental firing or press furnace (10) that enables the production of at least one dental restoration part (62). The dental firing or press furnace is provided with a firing space (12) that is heatable with the aid of a heating device (22), preferably, a resistance heating device. A heat-conducting element (50) having a specific thermal conductivity of at least 100 W/mK is arranged on the floor of the firing space (12).
Claims20
A dental firing or press furnace for the production of at least one dental restoration part, comprising
- a firing space that is heatable with the aid of a heating device, and
- a heat-conducting element having a specific thermal conductivity of at least 100 W/mK is arranged on the floor of the firing space.
A method for operating a dental firing or press furnace, wherein at least one dental restoration part is produced, the furnace comprising a firing space that is heatable with the aid of a heating device, and a heat-conducting element having a specific thermal conductivity of at least 100 W/mK is arranged on the floor of the firing space, the method comprising:
- prior to conducting a heat treatment process in the firing space, a heat-conducting element having a specific thermal conductivity of at least 100 W/mK, is introduced and
- conducting a heat treatment cycle for the production of the dental restoration part when the firing space and the heat-conducting element have reached a preset operating or stand-by temperature.
The method according to claim 20 wherein a material is used for the heat-conducting element that is harder than the bottom or base part of the dental firing or press furnace.
