Novel Strategy to Accelerate Bone Regeneration of Calcium Phosphate Cement by Incorporating 3D Plotted Poly(lactic‐co‐glycolic acid) Network and Bioactive Wollastonite
Inefficient bone regeneration of self‐hardening calcium phosphate cement (CPC) increases the demand for interconnected macropores and osteogenesis‐stimulated substances. It remains a challenge to fabricate porous CPC with interconnected macropores while maintaining its advantages, such as plasticity. Herein, pastes containing CPC and wollastonite (WS) are infiltrated into a 3D plotted poly(lactic‐co‐glycolic acid) (PLGA) network to fabricate plastic CPC‐based composite cement (PLGA/WS/CPC). The PLGA/WS/CPC recovers the plasticity of CPC after being heated above the glass transition temperature of PLGA. The presence of the 3D PLGA network significantly increases the flexibility of CPC in prophase and generates 3D interconnected macropores in situ upon…
