Figure 9: HAADF STEM images of (a) the SIT implant-bone interface after 12-week implantation. Bone growth around the nanoscale features was observed (arrow). (b) Ordered collagen fibrils, representative of mature bone, are noted adjacent to the implant at 12 weeks, while at 3-week implantation (c) partially disorganized collagen fibrils, representative of newly developing woven bone, are noted adjacent to the implant, consistent with the new bone structure.
