Abstract

Bioactive bone cement composite was prepared by mixing beads of PMMA, methylmethacrylate monomer, benzoyl peroxide as free radical initiator and bioglass powder. The latter consisted of SiO2, CaO and P2O5 was produced by the solgel method. The structure of PMMA beads, glasses and bone cement composite were investigated by TG/DTG, FTIR, XRD and SEM/EDS. The in vitro bioactivity was carried out by immersing specimens of the cement composite in simulated body fluid (SBF) at 37 0C and pH 7.4 for a reaction time period of 14 days..
