Figures 4–9. Figure 4. No gaps or dense fibrous connective tissue were found at the bone-metal interface (toluidine blue and basic fuchsin, original magnification ×12). Figure 5. No apical epithelial migration was found (toluidine blue and basic fuchsin, original magnification ×50). Figure 6. Compact, mature bone with well-delineated osteons was present at the implant interface (toluidine blue and basic fuchsin, original magnification ×200). Figure 7. Aspect of the peri-implant bone in polarized light. Most of the lamellar bone was arranged concentrically around a Haversian canal (polarized light, original magnification ×50). Figure 8. Higher magnification of peri-implant bone in polarized light. Most Haversian systems ran perpendicular to the major axis of the blade (polarized light, original magnification ×100). Figure 9. Distribution of the bone lamellae around the blade implant (polarized light, original magnification ×200)
