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. |
