Development of bioactive bone cement and its clinical applications.

摘要: Abstract This paper is a summary of already published papers on the bioactive bone cement (BA cement) which consists CaO–SiO2–P2O5–MgO–CaF2 (AW glass–ceramic) powder and bisphenol-a-glycidyl methacrylate (Bis-GMA) resin. Two types BA cement, dough injection type, were prepared by changing their chemical compositions slightly. They harden in few minutes exhibiting much lower curing temperature than PMMA cement. have significantly higher compressive, bending, tensile strengths character bonding directly with 4–8 weeks vivo. Intercalary prosthetic replacement femur total hip performed dogs using either or Mechanical tests demonstrated that fixation these prostheses increased time greater those tested at any time. Results histological examinations showed direct between bone, trabeculae around mantle grew time, while an intervening soft tissue layer was always observed cement–bone interface. used aged patients to instal prosthesis cases revision femoral neck fracture.
