Figure 7

Histomorphometric analysis of the bone area density. Within a circular band around the implant that was 250 μm (0.25 mm) thick, the red-dyed bone was marked, and the bone area (using only the red-dyed areas) was calculated. BA/TA (%) = bone area in the band/total area of the band. A representative image of a PEO implant at 4 weeks is presented (Van-Gieson stain; magnification, ×4).
