Fully-Interconnected Pore Forming Calcium Phosphate Cement
Calcium phosphate cement that foams fully-interconnected porous structure along with its gradual replacement to bone may be ideal for bone defect reconstruction. In the present study, α-tricalcium phosphate (αTCP) microspheres were exposed to acidic calcium phosphate solution. It was found that the αTCP microspheres set in approximately 10 min to form fully-interconnected porous structure. The porosity was approximately 50% and the pore size was 300µm. The surface of the porous body was dicalcium phosphate dihydrate whereas the inside was αTCP.
