PROBLEM TO BE SOLVED: To provide a resin artificial tooth which reduces a defect occurrence, such as a topical shrinkage, cracking, white turbidity, or chipping by reducing a distortion occurring inside of a resin artificial tooth, and which can be molded under a pressurization and heat condition where air bubble-mixing is not caused by foaming, in a molding step of the resin artificial tooth.SOLUTION: The invention relates to a resin artificial tooth containing a chain transfer agent, such as a monofunctional polymerization monomer with a boiling point of 50-200°C, a non-crosslinking (meta) acrylate polymer, a polymerization initiator, and a terpenoid compound. The chain transfer agent is γ-terpinene.COPYRIGHT: (C)2016,JPO&INPIT【課題】レジン人工歯の成形加工段階において、レジン人工歯の内部で発生するひずみを低減することにより局所的な収縮、割れ、白濁、欠けなどの不良の発生を抑制し、且つ発泡による気泡混入がない加圧加熱条件下による成形加工が可能なレジン人工歯の提供。【解決手段】50~200℃の沸点を有する単官能性重合性単量体、非架橋性(メタ)アクリレート系ポリマー、重合開始剤、およびテルペノイド系化合物のような連鎖移動剤を含むレジン人工歯。連鎖移動剤がγ-テルピネンであるレジン人工歯【選択図】なし
