ABSTRACT:
Disclosed is an artificial tooth that is structured such that the tooth is firmly held in its proper position in a core until a plate resin is fully polymerized and cured in succession to the manufacture of a wax denture. To this end, the artificial tooth has on its portion to be embedded into the core a projection for a temporary bond with the core. Also disclosed is a manufacturing method of an acrylic resin denture comprising the steps of forming a projection for a temporary bond with a core, on the portion of a finished artificial tooth to be -embedded into a core material before the finished artificial tooth is embedded into the core by applying a drop of resin that is of the same type as the material of the artificial tooth, and the step of removing the core along with the projection after a plate resin is polymerized. Instead of the application of a resin drop, a resin pellet can be glued on the portion of the finished artificial tooth to be embedded into a core material before the finished artificial tooth is embedded into the core.
