The manufacturing method of a prosthetic appliance for the upper jaw comprises a step of closely adhering a fixing leg of a partial prosthetic appliance in the upper part of a glass fiber frame; a step of polymerizing by combining the upper part and the lower part of the flask and pressing the glass fiber, the partial prosthetic appliance and a resin; and a step of completing the final partial prosthetic appliance for the upper jaw by separating the partial prosthetic appliance for the upper jaw after completion of the polymerization, polishing and abrading. According to the present invention, a manufacturing method of a partial prosthetic appliance for the upper jaw is provided, which is strong against various stress and external impacts while being thin and light by using a mesh type glass fiber, is able to minimize the time for manufacturing a partial prosthetic appliance, has a beautiful appearance as transparent materials are applicable, and provides the effect that no irritation feeling is provided to a user by minimizing the thickness. [Reference numerals] (S100) Manufacture main model after obtaining intra-oral impression by using individual tray from jaw having natural teeth; (S102) Manufacture lead partial prosthetic appliance by aligning artificial teeth after manufacturing bite plate with wax from main model; (S104) Put lead partial prosthetic appliance with artificial teeth aligned into flask, firstly bury under gypsum and harden it; (S106) Coat gypsum releasing agent on gypsum cast, which has been hardened after being firstly buried under gypsum, secondly bury under gypsum, and harden it with combining upper part and lower part; (S108) Once secondly buried gypsum is hardened, melt wax in bite plate by putting flask into hot bath, and separate upper part and lower part of flask; (S110) Manufacture mesh type glass fiber frame, fill resin in upper part and lower part of flask, and fix hardened glass fiber frame to top of filled resin; (S112) Position to closely adhere fixing leg of partial prosthetic appliance to top of glass fiber frame; (S114) Polymerize by pressing glass fiber, partial prosthetic appliance and resin after combining upper part and lower part of flask; (S116) Separate partial prosthetic appliance for upper jaw from flask, and polish to complete final partial prosthetic appliance for upper jaw |
