  • Publication number: 20190083211
    Abstract: Disclosed is a method of manufacturing a denture prosthesis by using a denture molding flask made of heterogeneous materials, the denture molding flask being composed of a left body (110) and a right body (120) coupled to each other to form an assembled structure, in which: a resin injection hole (104) is formed at a top portion of the assembled structure; an investment material injection hole (103) is provided to be spaced from the resin injection hole (104); a wax outlet (106) is formed at a bottom portion of the assembled structure such that molten wax is discharged out of the assembled structure when a wax denture base and an investment material in the assembled structure are heated and melted; and a void that is formed due to the wax denture base being melted is refilled with resin, wherein the left and right bodies (110, 120) are made of different materials.

  • Patent number: 9603684
    Abstract: Disclosed is an apparatus for manufacturing a tooth model aids. The apparatus for manufacturing a tooth model, which is configured to dewax when molding a tooth model so as to manufacture a dental denture, may include an outer housing, an inner container installed in an inside of the outer housing, a flask unit installed in an inner space part of the inner container. The flask unit includes a mounting plate on which a flask is configured to be mounted, and a cover, the mounting plate of the flask unit includes a wax collection hole on a bottom of the mounting plate, and the cover includes a nozzle which is configured to selectively inject hot water or steam to the flask, the nozzle being formed at a location corresponding to a location of the flask.
