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.

A method for producing an implant blank (100), in particular a dental implant blank from a starting body, said implant blank (100) comprising at least one first area, which is a surface area (102), and a second area, which is a core area (101), wherein the surface area (102) has at least one bioactive surface material (502) and extends from at least one first surface (103) in the direction of the core area (101), and the core area (101) has at least one carrier material that can be subjected to mechanical load. The starting body has a porosity for controlling a targeted distribution of the bioactive surface material (502) within the starting body and is loaded with a solution (500) of the bioactive surface material (502) in a first step, which is a loading step. In a second step, which is a distribution control step, the distribution of the bioactive surface material (502) within the starting body is controlled such that the solution (500) has a higher concentration within the surface area (102) than within the core area (101), the control being effected by regulating one or more environmental parameters in a closed environment (200), in particular by regulating the humidity and/or the pressure and/or the temperature.

Process and systems for molding or forming products from thermosetting plastics. The system utilizes a deformable container that is placed within the cavity of the housing of the mold with the resins and initiator mixed therein. As a piston slides into the cavity, the upper edges of the container engage between the housing and the piston to seal the housing form leakage. The pressure of the piston along with heat on the housing enable the curing process to be controlled to minimize shrinkage and porosity.
