Abstract—
We have developed a method for the preparation of macroporous carbonate hydroxyapatite-based matrices with the use of the technology of self-setting cements for surgical osteology. Macroporosity of osteoconductive calcium phosphate matrices was produced by adding paraffin granules to a dry cement mixture, followed by organic solvent extraction of the granules from matrices hydrated in an aqueous solution. In vivo tests of the resultant materials demonstrated high biocompatibility with pronounced angiogenesis, which was achieved via additional treatment with supercritical carbon dioxide.
