EDS data for the Ca/P atomic ratio in different regions of 13–93 bioactive glass scaffold with an oriented microstructure after implantation for 12 and 24 weeks in rat calvarial defects. (The regions of the scaffold examined are shown in Fig. 5a, e).
| Time (weeks) | Bone (B) | HA-like layer1 (H) |
SiO2-rich layer/core (S) | Glass core (G) |
|---|---|---|---|---|
| 12 | 1.72 ± 0.03 | 1.75 ± 0.04 | 2.6 ± 0.2 | 6.4 ± 0.4 |
| 24 | 1.52 ± 0.06 | 1.68 ± 0.03 | 1.9 ± 0.1 | - |
Ca/P atomic ratio for stoichiometric HA = 1.67
