[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.

Said photocurable resin composition contains, based on the total weight of the photocurable resin composition, (i) from 90 to 99.9% by weight of a radical polymerizable organic compound (A) selected from radical polymerizable monomers, oligomers, pre-polymers and mixtures thereof; and (ii) from 0.1 to 10% by weight of a photosensitive radical polymerization initiator (B). Said radical polymerizable organic compound (A) comprises, based on the weight of the radical polymerizable organic compound (A), from 0.5 to 20% by weight of a polyrotaxane compound comprising a polymer chain selected from polyethylene glycol (PEG), polypropylene glycol (PPG), polyethylene glycol - polypropylene glycol (PEG- PPG) block copolymer or polydimethylsiloxane (PDMS), onto which the cyclodextrin ring(s) is/are slipped and wherein the cyclodextrin is derivatized with at least a radical polymerizable group.
