The present invention, by implementing a manufacturing process of filling the ceramic raw material in the pattern in the form of a dental prosthesis and pressurizing it to a high temperature, so that the dental prosthesis can be produced more easily and excellent quality, pressurized such a dental prosthesis The present invention relates to a method for manufacturing a ceramic dental prosthesis and to a flask for performing the same. To this end, the manufacturing method of the present invention, in the process of manufacturing a dental prosthesis made of a ceramic material, the step of designing the shape of the desired tooth, and manufacturing the pattern core of the tooth through the processing machine by the designed data； Injecting the pattern core into the flask to bury the heat-resistant investment material, and then injecting the flask into a heating furnace and heating to a predetermined temperature to form a pattern in the investment material of the flask by combustion of the pattern core； Filling a ceramic raw material for producing a dental prosthesis in the pattern, and putting a flask filled with the ceramic raw material into a sintering furnace to press-sinter the ceramic raw material filled in the pattern to a predetermined temperature to form a dental prosthesis； ； Taking out the pressurized sintered dental prosthesis from the flask, and finishing the product of the dental prosthesis taken out by the polishing machine to complete the product. In addition, the flask of the present invention, in the tool is filled with a buried material forming a pattern for producing by pressing and sintering the dental prosthesis, the main body having a filling space formed therein so that the buried material is filled therein, and At least one side wall of the filling space is configured to form a fixed surface to prevent rotation after the investment material is cured.본 발명은, 치아보철물의 형태로 된 패턴의 내부에 세라믹 원료를 충전하여 이를 고온으로 가압소결하는 제작과정을 구현하므로써 치아보철물이 보다 손쉽고 우수한 품질로 제작될 수
