Enhancing the porosity of biphasic calcium phosphate using polyethylene glycol as the porogen for bone regeneration applications.

Biphasic calcium phosphate (BCP) has been used as a material to support bone grafting, repair, recovery, and regeneration over the past decades. However, the inherent weakness of BCP is its low porosity, which limits the infiltration, differentiation, and proliferation of bone cells. To address this issue, porous BCP was synthesized using polyethylene glycol (PEG) 1000 with weight ratio ranging from 20%-60% in BCP as the porogen through the powder-forming method.
