Abstract | Two bioactive bone cements were compared with poly(methylmethacrylate) (PMMA) cement. Cement A was prepared from precipitated hydroxyapatite and tricalcium phosphate, using an aqueous solution of Na 2HPO
4. Cement B was prepared by crushing a bioactive glass composed of SiO
2, CaO, P
2O
5 and Na
2O. The powder was mixed with NH
4H
2PO
4/(NH
4)
2 PO
4 aqueous solution buffered at pH = 7.4. The bioactive cements exhibited different in vivo behaviors but both performed better than PMMA cement.
