Provided is a method for manufacturing a denture using a putty which reduces manufacturing costs by simplifying processes. The method for manufacturing the denture comprises the following steps: i) providing a denture model; ii) providing a putty mold by covering the denture model with the putty and curing the same; iii) providing an investment model by injecting the investment into the putty mold; iv) casting a frame for denture using the investment model; v) fixing the frame for denture on the denture model; vi) fixing the artificial teeth on the frame for denture using artificial gum; vii) providing a molding box which surrounds the artificial teeth and artificial gum using the second putty; viii) removing the artificial gum; and ix) curing at room temperature by providing the resin to a space surrounded by the second putty. [Reference numerals] (S10) Provide denture model; (S20) Provide putty mold by covering and curing the denture model with putty; (S30) Provide investment model by injecting investment into the putty mold; (S40) Cast frame for the denture using the investment model; (S50) Fix the frame for denture on the denture model; (S60) Fix the artificial teeth on the frame for denture using artificial gum; (S70) Provide molding box which surrounds the artificial teeth and artificial gum using the putty; (S80) Remove the artificial gum; (S90) Cure at room temperature by providing resin to a space surrounded by the putty공정을 단순화하여 제조 비용을 절감한 틀니의 제조 방법을 제공한다. 틀니의 제조 방법은, i) 틀니 모형을 제공하는 단계, ii) 틀니 모형을 제1 퍼티로 덮고 경화시켜서 퍼티 주형을 제공하는 단계, iii) 퍼티 주형에 매몰재를 주입하여 매몰재 모형을 제공하는 단계, iv) 매몰재 모형을 이용하여 틀니용 프레임을 주조하는 단계, v) 틀니용 프레임을 틀니 모형 위에 고정시키는 단계, vi) 인공치아를 틀니용 프레임 위에 초로 고정하는 단계, vii) 제2 퍼티를 이용하여 인공치아와 초를 둘러싸는 주형틀을 제공하는 단계, viii) 초를 제거하는 단계, 및 ix) 수지를 제2 퍼티로 둘러싸인 공간에 가압 제공하여 상온 경화시키는 단계를 포함한다.
