Bone Formation in Grafts with Bio-Oss and Autogenous Bone at Different Proportions in Rabbit Calvaria

Figure 3

Photomicrographs showing bone formation in different groups: (a, b) Group I (100% Bio-Oss), (c, d) Group II (75% Bio-Oss + 25% autogenous bone), (e, f) Group III (50% Bio-Oss + 50% autogenous bone), and (g, h, i) Group IV (100% autogenous bone). Hematoxylin and eosin staining of all groups. Bars: 100 μm. Residual particles of biomaterial (B), newly formed bone (NB), bone marrow (BM), autogenous bone graft (AG), osteocyte (arrow), and blood vessels (BV). Extracellular matrix of bone marrow seems to be replaced by adipose tissue (arrowhead). Dotted squares in (a), (c), and (e) represent the areas observed at higher magnification in (b), (d), and (f), respectively. Dotted rectangles (1) and (2) in (g) represent the areas observed at higher magnification in (h) and (i), respectively.
