Title:
DENTURE MOLDING FLASK HAVING CHECK VALVE INSTALLED THEREIN AND METHOD FOR MANUFACTURING DENTURE PROSTHESIS USING DENTURE MOLDING FLASK MADE OF HETEROGENOUS MATERIALS
Document Type and Number:
WIPO Patent Application WO/2017/142352
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a denture prosthesis using a denture molding flask made of heterogenous materials and, more particularly, to a method for manufacturing a denture prosthesis using a denture molding flask made of heterogenous materials, wherein: left and right bodies (110, 120) are coupled to fabricate a denture prosthesis; a resin injection opening (104) is formed on the upper coupling portion, which couples the left and right bodies (110, 120), such that resin is injected; an investment injection opening (103) is formed in a position spaced from the resin injection opening (104) by a predetermined distance such that gypsum, which is an investment, is injected; a space portion is formed inside the left and right bodies (110, 120) such that a denture base made of wax is inserted into the space portion, and an investment is then injected from the investment injection opening (103); a wax discharge opening (106) is formed on the lower surface of the coupling portion of the left and right bodies (110, 120) such that, when the denture base made of wax and the investment are inserted into a hollow portion (101) and then are heated, the molten wax is discharged; and resin is injected into the empty space portion, after the denture base is melted, through the resin injection opening (104) such that the same is refilled, thereby molding a denture prosthesis. The left and right bodies are made of heterogenous materials such that, during thermo-polymerization of the dental prosthesis that is manufactured inside the left and right bodies, polymerization contraction/deformation is minimized.
