Figure 4. Histologic views of wound healing at day 7 with light microscopic findings (H&E stain, 100× magnification). Newly formed bone was seen from the cutting area of the cortical bone toward the implant surface (black arrows). New bone was also formed from the implant surface (white arrows). Bone formation was found to occur in the marrow area, mainly behind the existing cortical bone. Histologic views were observed around both the anodized (A) and modSLA (B) implants. Figure 4.
