PROBLEM TO BE SOLVED: To provide a highly elastic cement for cementation, having a buffering action. SOLUTION: The cement material for the cementation, includes 14.9 to 99.6 wt.% of a radially polymerizable urethane-based oligomer or urethane methacrylate-based oligomer,≤49.8 wt.% of a methacrylate, and≤70 wt.% of at least one filler selected from the group consisting of methacrylate polymers, methacrylate copolymers, urethane acrylate-based polymers, urethane methacrylate-based polymers and inorganic fillers. The highly elastic cement for the cementation is prepared by adding 0.03 to 1 wt.% of a polymerization initiator and 0.03 to 1 wt.% of an amine to the cement material. COPYRIGHT: (C)2009,JPO&INPIT
