Abstract
Chondroitin-4-sulfate sodium salts, sodium dodecyl sulfate and polycarbonic acid were added to improve the injection properties and mechanical properties for α-TCP-TeCP-DCPD bone cement system α-tricalcium phosphate and tetracalcium phosphate were prepared by heating a mixture of calcium hydrogen phosphate and calcium carbonate at 1500°C for 6h in furbace followed by quenching at room temperature. The viscosity was decreased by added amount of dispersion agent was increased. In this study, sodium dodecyl sulfate was the most effective material to reduce the viscosity. However setting time was longer when the added amount of dispersion materials was increased. The compressive strength increased when the amount of dispersion agents was increased, because liquid content can be reduced.
