摘要:
Problem to be solved: to provide a composition of a hard shrinking hard tissue having a small polymerization shrinkage rate and a hard tissue repair kit.Monomer (a),A hard tissue repair composition comprising polymer powder (b) and polymerization initiator (c);Among the components contained in the hard tissue repair composition, a hard tissue repair composition wherein the cumulative ratio of the powder particles having a aspect ratio of 1.00 or more and less than 1.10% in the whole powder particle is 50% by mass;AndMonomer (a) contained in this hard tissue repair compositionEach component of polymer powder (b) and polymerization initiator (c) isA hard tissue repair kit having a member accommodated in three or more parts in any combination.No selection【課題】重合収縮率が小さい低収縮性の硬組織補修用組成物及び硬組織補修用キットを提供する。【解決手段】モノマー(A)、重合体粉末(B)及び重合開始剤(C)を含む硬組織補修用組成物であって、硬組織補修用組成物に含まれる各成分のうち粉末粒子全体におけるアスペクト比1.00以上1.10未満の粉末粒子の累積比率が50累積%以下である硬組織補修用組成物;並びに、この硬組織補修用組成物に含まれるモノマー(A)、重合体粉末(B)及び重合開始剤(C)の各成分が、任意の組合せで3つ以上に分割されて収容された部材を有する硬組織補修用キット。【選択図】なし
