Abstract: The invention relates to a sintering furnace (1) for components (15) made of a sintered material, in particular for dental components, comprising a furnace chamber (2) having a chamber volume (VK), wherein a heating device (5), a receiving space (9) having a gross volume (VB) located in the chamber volume (VK) and delimited by the heating device (5), and a useful region (10) having a useful volume (VN) located in the gross volume (VB), are disposed in the furnace chamber (2). The furnace chamber (2) has an outer wall (3) consisting of a plurality of walls having a wall portion (7) to be opened for introduction of a component to be sintered having an object volume (VO) into the receiving space (9). In the furnace chamber (2) the heating device (5) has a thermal radiator (6) having a radiation field (13) which is disposed on at least one side of the receiving space (9). At least the useful volume (NV) disposed in the receiving space (9) is disposed in the radiation field (13) of the radiator (6), wherein the maximum possible distance (d) of the component (15) to be sintered from the radiator (6) corresponds to at most twice the dimension (Dy) of the maximum useful volume (VN).

Abstract: The invention relates to a method for planning a heat treatment of a dental prosthesis part (1), in which a 3D model (9) of the dental prosthesis part to be produced (1) already exists. A temperature profile (16) for the heat treatment of the dental prosthesis part (1) is automatically determined by a computer (17) as a function of determined geometric parameters (10, 11, 12, 13) of the dental prosthesis part to be produced (1) and/or of determined material parameters of the dental prosthesis part to be produced (1).

Abstract: A method of manufacturing a dental restoration including a construction step (S2) of preparing construction data for a dental tool machine for machining the dental restoration from a workpiece. The construction data defines at least the geometry of the dental restoration within the workpiece. The method includes a starting step (S3) of starting machining of the dental restoration from the workpiece in accordance with the construction data. The method also includes a preparing step (S4) of starting preparing, before termination of the construction step (S2), the dental tool machine at least through equipping it with all the consumables essential for starting the starting step (S3), and completing preparing the dental tool machine before start of the starting step (S3).
