The present invention discloses a method for making a porous calcium phosphate article including i) preparing a shaped article from a paste containing a calcium phosphate cement, a pore-forming powder and a setting liquid; ii) immersing the shaped article in an immersing liquid for a period of time so that the pore-forming powder is dissolved in the immersing liquid, creating pores in said shaped article; and iii) removing the resulting porous shaped article from the immersing liquid, wherein the resulting porous shaped article has an improved compressive strength. The porous shaped calcium phosphate article of the present invention may be used as a tissue-engineered scaffold, medical implant or a reinforcing constituent of a composite.
A shaped porous calcium phosphate article comprising a hardened calcium phosphate cement body, wherein the article is adapted for use as a medical implant, wherein the porosity of the article is 50% to 90%, and wherein the porous calcium phosphate article has a compressive strength that is 0.4 MPa to 75.5 MPa.
