FIELD: medicine.
SUBSTANCE: invention refers to medicine. What is disclosed is a porous calcium phosphate hydraulic cement for bone tissue restoration, containing p-tricalcium phosphate powder, monocalcium phosphate monohydrate, and a tempering liquid representing 7-9% aqueous solution of citric acid; also, a cement powder comprises calcium carbonate granules in the following proportions (wt %): β-tricalcium phosphate - 67-75, monocalcium phosphate monohydrate -20-22, calcium carbonate granules - 3-13. The tempering liquid and cement powder are related as 0.75.
EFFECT: calcium phosphate cements are characterised by a combination of an ability to reaction hardening, an ability to be shaped, biocompatibility, the absence of toxic side effects, as well as a potential to be replaced by the newly formed bone tissue.
