Processing device of complete oral denture and tooth tray

摘要

Problem to be solved: to provide a multi-color layer processing structure of an entire oral denture and a toothed tray having a hard work piece having a hard distinction and a different color arrangement by using a step of processing a multicolor layer, and having difficulty in positioning errors.The multi-color layer processing structure comprises a hard color material mass 10 having a predetermined positioning portion and is formed in the following processing steps. (a) the hard color material lump is positioned in the processing apparatus to form a tooth shaped structure 12 of a predetermined arrangement form at a portion of the hard color material lump. (b) the hard color material lump is fixed in the injection mold die box 13.(c) a soft rubber material L which is different from the color of the hard color material lump is injected into an injection molding die box, coated with a tooth like structure, and a soft rubber material is polymerized, and thereafter, it is formed into a gum material material lump, and the whole structural form of the polychromatic layer appears. (d) a hard color material mass and a gingival color material lump are taken out from an injection molding die box together, and (E) a dental pulp material lump is formed into a tooth shaped tray shape.Diagram
