Abstract: A firing tray for a furnace for dental ceramics having a plate for the placement on it of the firing material, wherein the plate is made as a base for the improvement of the application possibilities and the firing tray has additional wall elements which are designed for the placement on them of a further firing tray for the forming of a stack.

Abstract: The invention relates to a furnace for a dental prosthesis, or a partial dental prosthesis, comprising a furnace chamber, a plurality of heating elements for heating the furnace chamber, and a power connector for connecting the heating elements to a power grid, wherein means for limiting the power consumption of the furnace are provided in order to increase the application possibilities and improve the furnace performance.

Abstract: The invention relates to a firing furnace for a tooth replacement or tooth prosthesis, with a firing chamber, at least one heating element for heating the firing chamber, a control unit for controlling the operation of the firing furnace, and a housing at least partially surrounding the firing chamber, wherein the firing furnace comprises at least one thermoelectric element for utilizing the waste heat generated by the firing furnace.

Abstract: The invention relates to a furnace for the firing of dental prostheses or partial dental prostheses having a firing chamber, a heating device for the heating of the firing chamber, a firing tray arranged within the firing chamber during firing and a lifting mechanism for raising and lowering the firing tray. A moving mechanism is additionally provided by which the firing tray can be moved with an open firing chamber between a lifting position and a loading position laterally offset thereto.

Abstract: The invention relates to a combustion table for an oven for dental ceramics made of solid, highly temperature-resistant material, having a base, a top side, and a wall, wherein the combustion table is formed of at least two parts in order to improve the temperature resistance of the combustion table.

Abstract: The invention relates to a furnace for a dental prosthesis, or a partial dental prosthesis, comprising a furnace chamber, a plurality of heating elements for heating the furnace chamber, and a power connector for connecting the heating elements to a power grid, wherein means for limiting the power consumption of the furnace are provided in order to increase the application possibilities and improve the furnace performance.

Abstract: An apparatus for manufacturing muffles for producing dental prosthetic parts comprises a collar divided at least once in the peripheral direction to form a receiving space for an investment material in which at least one pattern for a dental prosthetic part is arranged before the filling with the investment material. At least one pattern holder simultaneously serves as a spacer for an injection plunger passage and a base part closes an open side of the collar. Holding means encompasses the collar to hold the collar together, with the collar being conical with respect to the longitudinal axis thereof at least in one section for simpler manufacture and better handling. The holding means includes at least one ring, in particular a rigid ring, which has a conical inner surface with which it is pushed onto the conical section in the collar.
