PROBLEM TO BE SOLVED: To provide an impression method using application of an impression material to an impressed body thinly and curing the impression material for improving impression accuracy.SOLUTION: An impression material 1 is thinly applied to an impressed body 1 and is cured once. Then, the cured impression material is used for impression. In the case where the impression material has a shrinkage factor of 10 percent during curing, when a thickness of the impression material is 100, a deformation amount is 10, and when a thickness of the impression material is 1, a deformation amount becomes 0.1 and a deformation amount is lowered. By curing the impression material once and changing a dimension, dimension change due to curing hardly occurs even being used again, so that impression accuracy is improved corresponding to the reduction in the deformation amount of the impression material.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】印象の精度を向上する為に、印象材料を被印象体に薄く塗布し硬化させることを利用した印象方法を提供する。【解決手段】印象材料1を被印象体2に薄く塗布し一度硬化させる。その後に硬化した印象材料を利用して印象する。硬化時の収縮率が10パーセントの印象材料の場合、印象材料の厚みが100の時に変形量は10であるが、印象材料の厚みが1の場合の変形量は0.1になり変形量は低くなる。印象材料を一度硬化させ寸法変化させてしまう事で、再度利用しても硬化にともなう寸法変化は起こらない為、印象材料の変形量が減った分、印象の精度が向上する。【選択図】図1
