PROBLEM TO BE SOLVED: To provide orthodontic practice appliance that can be manufactured inexpensively and is improved in terms of the temperature uniformity of an orthodontic gingival part made of wax when heated.SOLUTION: An orthodontic practice appliance 1 according to the present invention includes: an orthodontic tooth row 23 for orthodontic practice； an orthodontic gingival part 22 that holds the orthodontic tooth row 23 and is softened by the application of heat； and a metal member 24 that is placed inside the orthodontic gingival part 22 and has an exposure portion exposed to the outside. According to the present invention, when the orthodontic practice appliance 1 is immersed in hot water, the exposed metal member 24 is heated. The metal member 24 extends inside the orthodontic gingival part 22. Therefore, the orthodontic gingival part 22 is heated not only from the surface thereof in direct contact with the hot water but also from the inside of the orthodontic gingival part 22 by heat transmitted through the heated metal plate 24. Accordingly, heat is uniformly transmitted to the orthodontic gingival part 22.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】安価に製造可能で、加熱した際にワックス製の矯正用歯肉部の温度の均一性が向上した歯列矯正実習用装置を提供する。【解決手段】本発明の歯列矯正実習用装置１は、矯正実習用の矯正用歯列２３と、前記矯正用歯列２３を保持するとともに、加熱によって軟化する矯正用歯肉部２２と、前記矯正用歯肉部２２の内部に配置されるとともに、外部に露出した露出部を有する金属部材２４と、を備える。本発明によると、歯列矯正実習用装置１を湯に浸漬させると露出した金属部材２４が加熱される。金属部材２４は、矯正用歯肉部２２の内部を延びている。したがって、矯正用歯肉部２２は、湯に直接触れている表面だけでなく、加熱された金属部材２４を熱が伝わり、矯正用歯肉部２２は内部からも加熱される。このため、矯正用歯肉部２２には、均等に熱が伝わる。【選択図】図１
