Description: The patients own cells are seeded onto the scaffold and allowed to attach and start producing new bone. The construct is implanted into the defect site, where eventually the polymer will biodegrade and be completely removed, leaving a natural autogenous bone graft. This technique is particularly useful for large defects, or where the host bed is compromised due to disease, although it is still at the research stage. Average Pore Size 350-550 micrometre, porosity estimated at 35-45%.
