Maxillary Sinus Floor Augmentation Using an Equine-Derived Graft Material: Preliminary Results in 17 Patients

Figure 1

Histologic analysis: Hematoxylin-Eosin staining, magnification of 10x (a, c, e) and 20x (b, d, f). The histologic analysis reveals the presence of predominant bone tissue (black arrow), fibrous tissue (black square), and residual grafting material (black star). The grafting material is in direct contact with the bone that completely surrounds it (a, b) or partially engulfed in the newly formed fibrous tissue (c, d) or fragmented in small residual granules surrounded by a mixture of fibrous tissue and bone spicules (e, f).
