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

Figure 8

Bioapatite-collagen (toluidine blue and acid fuchsin): (a) trabecular bone with marrow spaces and residual biomaterial particles was observed (original magnification 12X); (b) osteoblasts were observed in the process of apposing bone directly on the particle surface. Marrow spaces were colonized by small and large blood vessels in close proximity to the new bone and to the particles (original magnification 40X); (c) moderate inflammatory infiltrate and multinucleated giant cells, probably osteoclasts, were observed directly on the biomaterial particles surface (original magnification 400X).
