A bioactive cement comprises a filler consisting of nonalkali glass powder containing Ca, monomer containing hydrophilic dimethacrylate, a polymerization starter, and a polymerization promoter. The nonalkali glass powder containing Ca comprises a composition by weight of 40-50 % CaO, 30-40 % SiO2, 10-20 % P2O5, 0-10 % MgO, and 0-2 % CaF2. The hydrophilic dimethacrylate is 2,2-bis[4-(3-methacryloxy-2-hydroxy propoxy)phenyl] propane. The bioactive cement is capable of forming a hydroxyapatite layer on a surface of a hardened cement body when the hardened cement body is brought into contact with body fluid. |
