method to produce an artificial tooth and liquid dental photocurable resin composition

摘要

The present invention relates to providing a method for easily and smoothly manufacturing, in a short period of time, specifically less than one week, an artificial tooth by the use of a dental photocurable resin composition, said artificial tooth having strength, Abrasion resistance, hardness, low water absorption, aesthetic property, functionality and the like. the method includes (a) a liquid dental photocurable resin composition containing a radical polymerizable organic compound (a), a filler (b) and a photosensitive radical polymerization initiator (c) which is fitted with a modeling container, (b ) raising the cured resin layer to a layer formed in step (a), thereby allowing the dental liquid photocurable resin composition to flow into the space between the underside of the cured resin layer and the container bottom face (c) repeat the operation of step (b) until the target artificial tooth is obtained.
