| Abstract Scope |
Self-setting calcium phosphate cements (CPCs) are successfully used in various dental and orthopedic applications for bone repair. However, CPCs have shown poor injectability due to phase separation during extrusion. As such, there is a need to improve the delivery of CPCs without negatively impacting the setting time and mechanical properties. To solve this issue, microspheres made from calcium phosphate powder were used to create an injectable CPC. CPC injectability, setting time, and mechanical strength were tested by comparing CPCs made from either microspheres and irregularly shaped particles. The results of this provided a microsphere CPC with improved injectability without detriment to the mechanical properties. These results were further explored in applications of 3D-printing, where CPCs were successfully extruded as a bio-ink into complex structures. With improved injectability and potential in 3D-printing, microsphere CPCs can be used as bone grafts to improve clinical surgeries where minimally-invasive techniques are desired. |
