PROBLEM TO BE SOLVED: To prevent wax deformation due to heating shrinkage, and enable guarantees even if the shrinkage occurs in the prosthesis of the molded teeth due to the occurrence of the shrinkage of a metal material, and thereby enable the molding of the denture to be easily worn.SOLUTION: Wax 1 molded in a required shape of teeth is contained to an embedding material 2, and a recess part 3 of the wax 1 becoming a shaded concave are ground to a predetermined size and increased. An embedding material 4 is filled again to this recess part 3 being ground and increased, and is internally installed to a mold frame body 5. The mold frame body 5 is heated and the wax 1 is eliminated, and the denture is formed by pouring a metal material 8 of a denture material from a casting opening 6. Preferably, digital data may be acquired concerning the shape of a required tooth, and the recess part 3 of the wax 1 may be enlarged to a predetermined size of 0.3-2.5%.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2020,JPO&INPIT【課題】 加熱収縮によってワックスの変形防止や、金属材の収縮が生じて成形歯の補綴物に収縮が生じても、その保証ができて、義歯の成形品を容易に装着できることにある。 【解決手段】 所要の歯の形状に成形したワックス１を埋設材２に内包して、陰型の凹状となったワックス１の凹所部３を所定の大きさに研削して拡大し、この研削して拡大した凹所部３に再び埋設材４を充填して鋳型枠体５に内装し、上記鋳型枠体５を加熱してワックス１を消滅して鋳込み口６から義歯材の金属材８を流し込んで義歯を形成するものである。所要の歯の形状についてディジタルデータを取得し、ワックス１の凹所部３を０．３～２．５％の所定の大きさに拡大することが好ましい。【選択図】 図３
