Provision of [challenges] gingival sulcus extension for insertion material. A1 The present invention relates to gingival sulcus extension for insertion material novel. Includes as a component a hydrophilic paste to the hydrophilic paste, and the weight percentage based on the total weight of the insertion member, and astringents 5% to 15% of the gingival sulcus expansion insert material of the present invention water and 30% to 60% the binder of 25% to 50% and a wetting agent 0-20%, and the total amount of the wetting agent and water at 35 to 65% by weight of the total weight of the insert member Yes, astringent emissions of 5 minutes after the insertion material: less than 20%, astringent emissions after 10 minutes: less than 40%, astringent emissions after 15 minutes: less than 50%, after 30 minutes I show the astringent emissions to remain less than 80%: astringent emissions: astringent emissions less than 60%, after 60 minutes. [Selection] Figure Figure 1【課題】歯肉溝拡張用挿入材の提供。【解決手段】本発明は、新規な歯肉溝拡張用挿入材に関するものである。本発明の歯肉溝拡張用挿入材は、親水性ペーストを構成成分として含み、上記親水性ペーストは、上記挿入材の総重量に対して重量パーセントで示すと、5~15%の収斂剤と;25~50%の粘結剤と;30~60%の水と;0~20%の湿潤剤とを含み、水と湿潤剤の合計量が上記挿入材の総重量の35~65重量%であり、上記挿入材は、5分後の収斂剤放出量:20%未満、10分後の収斂剤放出量:40%未満、15分後の収斂剤放出量:50%未満、30分後の収斂剤放出量:60%未満、60分後の収斂剤放出量:80%未満と推移する収斂剤放出量を示す。【選択図】図1
