Figures 3–7. Figure 3. The implant was surrounded by lamellar and woven bone. The bone was in close contact with the implant surface. At the coronal level, no infrabony pocket, Howship lacunae, or osteoclasts were present (acid fuchsin and toluidine blue, original magnification ×12). Figure 4. Higher magnification of the coronal portion of the bone-implant interface. No infrabony pockets or osteoclasts were present (acid fuchsin and toluidine blue, original magnification ×100). Figure 5. Lamellar and woven bone were observed in direct contact with the implant surface; no gaps or connective tissue were present at the bone-implant interface. The first bone-to-implant contact was found at about 1 mm from the shoulder of the implant. The pre-existing bone quality was type D4. No apical epithelial migration was found. No inflammatory infiltrate was present around the implant (acid fuchsin and toluidine blue, original magnification ×100). Figure 6. At the coronal level, osteoblasts were also found in direct contact with the implant surface and producing osteoid matrix directly on the metal surface. Only in a few areas in the coronal portion was it possible to see that this bone was going through an active remodeling process with the presence of some well-structured Haversian canals. Newly formed, strongly stained bone lamellae with a width of 200 to 400 μm were present around the implant (acid fuchsin and toluidine blue, original magnification ×200). Figure 7. In the apical portion of the implant, osteoblasts and newly formed bone were present. No osteoclasts were present. Few marrow spaces were observed directly on the implant surface. The quality of the bone around the apical portion of the implant was poor. Only a few newly formed thin bone trabeculae were present at a distance from the implant surface. No well-structured Haversian canals were present in the bone located at the apical portion of the implant (acid fuchsin and toluidine blue, original magnification ×200)
