PROBLEM TO BE SOLVED: To provide a model tooth for dentistry training having excellent cut feelings closer to a natural tooth, allowing manufacturing with a high-performance method, and a manufacturing method of a model tooth for dentistry training capable of manufacturing the model tooth for dentistry training at a high performance.SOLUTION: A model tooth for dentistry training includes a dentin part and an enamel part joined to the dentin part. The dentin part and the enamel part include a urea resin. A manufacturing method of the model tooth for dentistry training preferably includes: an injection formation process of forming the dentin part and the enamel part by injection molding using a urea resin or a urea resin composition and a joining process of joining the dentin part and the enamel part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】天然の歯牙に近い良好な切削感を有し、高効率な方法でも生産可能である歯科実習用模型歯と、当該歯科実習用模型歯を高効率で製造可能な歯科実習用模型歯の製造方法とを提供すること。【解決手段】象牙質部と、象牙質部に接合されるエナメル質部とを備える歯科実習用模型歯について、象牙質部及びエナメル質部とが尿素樹脂を含む構成とする。当該歯科実習用模型歯の製造方法としては、尿素樹脂又は尿素樹脂組成物を用いる射出成形により、象牙質部と、エナメル質部とを形成する射出形成工程と、象牙質部と、エナメル質部とを接合する接合工程と、を含む方法が好ましい。【選択図】図1
