Denture molding flask having check valve installed therein and method for manufacturing denture prosthesis using denture molding flask made of heterogenous materials

Abstract

The 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 basemade 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.

Description

technical field [0001] The present invention relates to a tooth box for denture molding with a check valve and a method for manufacturing denture accessories using the tooth box for denture molding of heterogeneous materials, and more specifically relates to a denture molding box with a check valve A method of manufacturing a denture aid using a denture box and a denture molding box using a heterogeneous material. A plaster model is placed in a box equipped with a check valve, and a prescribed denture base material is selected and used. It can be used to make partial dentures or complete dentures to prevent resin deformation. In addition, the left main body is made of metal material with high thermal conductivity, and the right main body is made of plastic material with low thermal conductivity. Background technique [0002] Generally speaking, a tooth box is used to make a model of a denture as a tooth shape auxiliary according to the user's tooth shape. Usually, in terms o...

AI Technical Summary

Problems solved by technology

[0010] However, with the existing products as described above, in the process of making a denture accessory, the dental form box is divided during the process of removing wax and inserting resin, so that there are problems in that the manufacturing time is long and the working environment unclean

[0011] In addition, after inserting the resin, when the divided tooth box is fixed with a jig, the denture auxiliary is distorted, so there is a problem that numerical errors occur, requiring re-production, etc., and the work efficiency is low.
