EXPERIMENTAL ASSESSMENT OF BONE CEMENTS PERFORMANCE

All performance index of six kinds of brands for domestic and import bone cement have been determined according to ISO 5833∶2002 《Implants for surgery——Acrylic resin cements 》. The result indicated that four kinds of brands bones cement achieved the standard request,two kinds of brands bones cement has not met the standard requirements. All the performance of the bone cement,such as the appearance,the liquid component stability ,the average maximum temperature ,the intrusion of the liquid powder mixture as well as the solidification average compressive strength,the average bending modulus,the average bending strength achieved the international standard request. C kind of brand bone cement the accuracy of liquid component contents and the accuracy of powder component contents have not achieved the standing operating procedure. B kind of brand bone cement average toughing time and the average setting time have not achieved the standing operating procedure.
