Abstract
The invention describes a new calcium phosphate cement powder, whose composition can best be described over the Ca/P molar ratio range of 1.35 to 1.40, most preferably 1.39, and whose two components were prepared by wet chemical synthesis procedures. One component is chemically-synthesized, bi-phasic alpha-TCP (Ca(PO), 95 wt %)+HA (Ca(PO)(OH), 5 wt %) powder, while the second component is again a chemically-synthesized, single-phase DCPD (CaHPO·2HO) powder. A setting solution (NaHPO·2HO) is used to form a self-setting calcium phosphate cement from the powder mixture. This cement can be used as bone filler or bone substitute in applications, which require higher rates of resorption.
