Comparative Histological and Histomorphometric Results of Six Biomaterials Used in Two-Stage Maxillary Sinus Augmentation Model after 6-Month Healing

Figure 6

Equine-derived bone (toluidine blue and acid fuchsin): (a) trabecular bone with large marrow spaces and biomaterial particles was observed. The biomaterial particles were located in the apical portion of the biopsy and they were surrounded by new bone (original magnification 12X); (b) the bone was in close contact with the granules and in some areas osteoblasts were observed in the process of apposing bone directly on the particle surface (original magnification 40X).
