Dental pressure delivery and impression acquisition system to provide automatic retracting and impression extraction of abutment teeth at a single stage. The material hardened by the pair simultaneously pulls the gingiva, extends the groove around the tooth, and obtains the impression of the tooth and the edge. A low viscosity hardened toothbrush pressure reducing material containing a converging material and a high viscosity hardened impression material are cured together.Since the viscosity of the high viscosity hardened impression material is higher than that of the low viscosity hardened gingiva pressure reducing impression material, the impression material of low viscosity hardened toothpaste is pushed into the gap or groove of the gum.単一段階で支台歯の自動圧排(self-retracting)及び印象採得を提供する歯科用圧排及び印象採得システム。対で硬化する材料が同時に歯肉を圧排し、歯周囲の溝を広げ、歯及び辺縁部の印象を採得する。収斂材を含有する低粘度硬化歯肉圧排印象材及び高粘度硬化印象材が一緒に硬化する。高粘度硬化印象材は高粘稠度で、低粘度硬化歯肉圧排印象材よりも粘度が高いため、低粘度硬化歯肉圧排印象材を歯肉の間隙又は溝に押し入れる。
