Calcium phosphate bone cements (CPC) are excellent materials for bone defect repair. CPC advantages over other calcium phosphate materials are ability to take the shape of any defect, easy incorporation of auxiliary materials and fast bioresorbtion rate. Traditionally CPC are formed by mixing calcium phosphate powder with water solution and cementing reaction starts upon mixing. This leaves a very limited time period for cement mixing and implantation. Recently the concept of pre-mixed CPC has been introduced where a paste consisting of calcium phosphate powder and non-aqueous liquid is implanted in tissue. The setting reaction in pre-mixed paste starts after implantation when non-aqueous liquid in cement paste is replaced by body fluids. In this work for the first time cement consisting of α-tricalcium phosphate (α-TCP), calcium dihydrogen phosphate and non-aqueous liquid is proposed.
