PROBLEM TO BE SOLVED: To provide a production method of a plate denture highly efficiently adjusting positions of artificial teeth when the artificial teeth are arranged in the plate denture.SOLUTION: A plate denture 100 is prepared, the plate denture including a plurality of artificial teeth 12 arranged at a socket part of a denture base 14. Secondly, a rectangular temporal fixing material 10 is arranged outside a gum so as to cover the gum part of the plate denture, and the artificial teeth 12 are temporarily fixed to the denture floor 14 (a temporal fixing step). Thirdly, an acrylic resin is injected in a gap between the socket part of the denture floor 14 and the artificial teeth 12, with the artificial teeth 12 temporarily fixed to the denture floor 14, using an injector 20 filled with the acrylic resin. After that, the acrylic resin is polymerized under a normal temperature (0°C-35°C), heated, or polymerized by light energy, and then, the artificial teeth 12 are permanently bonded to the plate denture 14 (a permanent bonding step).SELECTED DRAWING: Figure 1 【課題】人工歯を義歯床に配置する際に、人工歯の位置調整を精度良く行える有床義歯の製造方法を提供する。【解決手段】複数の人工歯１２を義歯床１４のソケット部に配置した有床義歯１００を準備する。次に矩形状の仮固定材１０を、有床義歯の歯肉部分を覆うようにして、歯肉の外側に配置し、人工歯１２は義歯床１４に仮固定する（仮固定工程）。次に人工歯１２を義歯床１４に仮固定した状態で、アクリル系レジンが充填された注入器２０を用いて、歯肉の内側（舌側）から、アクリル系レジンを義歯床１４のソケット部と人工歯１２との隙間に注入する。その後、アクリル系レジンを常温（０℃〜３５℃）で重合させ、又は、加熱して若しくは光で重合させ、人工歯１２を義歯床１４に本接着する（本接着工程）。【選択図】図１
