PROBLEM TO BE SOLVED: To provide a dental working model that can omit the complicated removal work after transfer, and can remove a molding resin plate easily and accurately, and provide a dental working model manufacturing apparatus and a dental working model manufacturing program.SOLUTION: A dental working model 10 includes: a model body 20 taken from a wearer and transferred of a shape to a molding resin plate and protrusions 30 continuously provided along a range S of the model body 20 transferred to the molding resin plate, and for removing a surplus portion from the molding resin plate transferred of the shape of the range S by a pressing force. When the molding resin plate is pressed to the model body 20 and transferred, the protrusions 30 pierce the molding resin plate and the bending of the molding resin plate progresses gradually from the tip to base end of the protrusions 30, and thereby perforations due to the protrusions 30 are enlarged and adjacent perforations are connected and the surplus molding resin plate is separated.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】転写後の煩雑な除去作業が省略でき、成形用樹脂板を容易に、かつ正確に除去することができる歯科作業模型および歯科作業模型製造装置並びに歯科作業模型製造プログラムを提供する。【解決手段】歯科作業模型10は、装着者から採得され、成形用樹脂板に形状が転写される模型本体20と、記成形用樹脂板に転写される模型本体20の範囲Sに沿って連続的に設けられ、範囲Sの形状が押圧により転写された成形用樹脂板から、余剰部分を除去するための突起部30とを備えている。成形用樹脂板を模型本体20に押圧して転写するときに、突起部30が成形用樹脂板に突き刺さり、徐々に成形用樹脂板が突起部30の先端から基端へ、成形用樹脂板の撓みが進行することで、突起部30による穿孔が大きくなり、隣接する穿孔同士が繋がって、余剰の成形用樹脂板が切り離される。【選択図】図1
