A sintering furnace for couponents made of a sintered material, in particular for dental components, having a furnace chamber having a chamber volume (VK). A heating device, a receiving space having a gross volume (VB) located in the chamber volume (VK) and delimited by the heating device, and a useful region having a useful volume (VN) located in the gross volume (VB), are disposed in the furnace chamber. The furnace chamber has an outer wall consisting of walls having a wall portion to be opened for introduction of a component to be sintered having an object volume (VO) into the receiving space. In the furnace chamber the heating device has a thermal radiator having a radiation field which is disposed on at least one side of the receiving space. At least the useful volume (NV) disposed in the receiving space is disposed in the radiation field of the radiator.

The invention relates to a method for producing a dental prosthesis from a prosthesis base and a plurality of prosthesis teeth, characterized by the following chronological steps: providing the prosthesis teeth and the prosthesis base, wherein the prosthesis base comprises a plurality of tooth sockets for locating the basal surfaces of the prosthesis teeth; applying a plastically deformable connecting means onto the tooth sockets and/or basally onto the prosthesis teeth; locating the prosthesis teeth into the tooth sockets of the prosthesis base and in this situation connecting with the aid of connecting means to the prosthesis base in such a way that the prosthesis teeth, after locating in the tooth sockets, are movable in relation to the prosthesis base, wherein the position and the alignment of the prosthesis teeth to the prosthesis base remain retained if no external force effect is exerted onto the prosthesis teeth; changing the position and/or the alignment of at least one prosthesis tooth in the prosthesis base; and hardening the plastically deformable connecting means, and securely connecting the prosthesis teeth in this situation to the prosthesis base, wherein the position and the alignment of the prosthesis teeth in relation to the prosthesis base are retained. The invention also relates to a dental prosthesis produced by such a method, and a set for carrying out such a method.

To provide a method for producing an artificial tooth which is excellent in strength, abrasion resistance, hardness, low water absorption, aesthetic property, functionality, and the like within a short time, especially less than 1 hour, smoothly and simply, without requiring skill using a dental photocurable resin composition. [Solution] Disclosed is a method for producing an artificial tooth, which includes the steps of: (a) accommodating a liquid dental photocurable resin composition containing a radical polymerizable organic compound (A), a filler (B), and a photosensitive radical polymerization initiator (C) in a shaping container having a light permeable bottom face, and irradiating the dental photocurable resin composition in the shaping container with light in a predetermined shape pattern through the light permeable bottom face of the shaping container in accordance with slice data every one layer based on three-dimensional CAD data relating to a tooth to form a cured resin layer having a shape pattern for one layer; (b) lifting up the cured resin layer for one layer formed in the step (a), thereby allowing the liquid dental photocurable resin composition to flow into the space between the lower face of the cured resin layer and the bottom face of the shaping container, and irradiating the dental photocurable resin composition between the lower face of the cured resin layer and the bottom face of the shaping container with light through the light permeable bottom face of the shaping container in accordance with slice data every one layer based on three-dimensional CAD data relating to a tooth to further form a cured resin layer having a shape pattern for one layer; and (c) repeating the operation of the step (b) until the objective artificial tooth is obtained.
