PROBLEM TO BE SOLVED: To provide a denture plate that, in copying at least one of the colors and patterns of the actual gum, can be decorated with a stable quality on a prescribed surface part of the denture plate, and also to provide a manufacturing method of the denture plate, a plate denture, and a manufacturing method of the plate denture.SOLUTION: The manufacturing method of a denture plate is that a first shape information containing the three-dimensional shape of the denture plate is acquired (S41), that information of a recessed shape is added to a prescribed surface part of the denture plate in the first shape information (S42), and that a second shape information is formed from the first shape information (S43). On the basis of this second shape information, a resin-made denture plate is formed by a first resin material, the resin-made denture plate having a recessed part on the surface part (S54), and a second resin material having a color different from that of the first resin material is formed on the recessed part (S8).SELECTED DRAWING: Figure 5COPYRIGHT: (C)2018,JPO&INPIT【課題】実際の歯肉の色調及び模様の少なくとも１つに似せて、義歯床の所定の表面部位を安定した品質により加飾することができる義歯床、義歯床の製造方法、有床義歯及び有床義歯の製造方法を提供する。【解決手段】義歯床の製造方法は、義歯床の三次元形状の情報を含む第１形状情報を取得し（Ｓ４１）、第１形状情報において義歯床の所定の表面部位に凹部形状の情報を加えて（Ｓ４２）、第１形状情報から第２形状情報を生成する（Ｓ４３）。この第２形状情報に基づいて、第１樹脂材料により形成され、表面部位に凹部を有する樹脂製義歯床が形成され（Ｓ５４）、第１樹脂材料の色調と異なる色調を有する第２樹脂材料が凹部に形成される（Ｓ８）。【選択図】図５
