ABSTRACT:
An excellent bioactive cement is provided which can chemically and firmly bond to teeth or bones of living bodies, adapt the shape of defected portions of bones or teeth of living bodies, harden quickly, and exhibit high initial strength, without forming inflammation to the surrounding tissue of living bodies. The bioactive cement is composed of glass powder comprising Ca as a main constituent, and an aqueous solution of ammonium phosphate as a hardening liquid for the glass powder, and is economical and stable without loosing the fixation between the artificial biomaterial and the bones or teeth of living bodies nor degradation thereof in the living bodies during a long period of use in the living bodies.
