PROBLEM TO BE SOLVED: To provide a method for manufacturing artificial teeth in a short time using a dental photocurable resin composition without the need for skill, the artificial teeth having excellent strength, wear resistance, hardness, aesthetics, functionality, etc., and low water absorption.SOLUTION: There is provided a method for manufacturing artificial teeth in which: (a) a liquid dental photocurable resin composition is placed in a molding container having an optically-transparent bottom surface, and one cured resin layer is formed by passing light through the optically-transparent bottom surface of the molding container to the dental photocurable resin composition in the molding container according to slice data for each layer based on three-dimensional CAD data for a tooth； (b) the cured resin layer formed in (a) is made to rise by one layer only, allowing the dental photocurable resin composition to flow between the bottom surface of the cured resin layer and the bottom surface of the molding container, and then light is passed through the optically-transparent bottom surface of the molding container to the dental photocurable resin composition to form another cured resin layer； and (c) the operation in (b) is repeated until an artificial tooth is obtained.COPYRIGHT: (C)2015,JPO&INPIT【課題】歯科用光硬化性樹脂組成物を用いて、強度、耐摩耗性、硬度、低吸水性、審美性、機能性等に優れる人工歯を、熟練を要せずに短時間に製造する方法を提供する。【解決手段】(a)光透過性の底面を有する造形容器に、液状の歯科用光硬化性樹脂組成物を入れ、造形容器内の歯科用光硬化性樹脂組成物に、造形容器の光透過性の底面を透して、歯に関する三次元CADデーターに基づく一層ごとのスライスデーターに従って光を照射して一層分の硬化樹脂層を形成し、(b)前記(a)で形成した硬化樹脂層を一層分だけ上昇させて該硬化樹脂層の下面と造形容器の底面との間に歯科用光硬化性樹脂組成物を流入させ、該歯科用光硬化性樹脂組成物に、造形容器の光透過性の底面を透して光を照射して一層分の硬化樹脂層を更に形成し、(c)人工歯が得られるまで前記(b)の操作を繰り返す人工歯の製造方法。【選択図】図１
