Figure 4: Histological findings of the tested implant after 28 days and 56 days of healing. (a) The implant is surrounded by dense cortical bone (CB) and newly formed bone in the bone marrow cavity. Moreover, woven bone (WB) combined with lamellar bone (LB) was observed in direct contact with the implant surface without the presence of fibrous tissue. Original magnification ×2.5. (b) Original magnification ×10. (c) The implant is surrounded by dense cortical bone (CB) and dense lamellar bone in the bone marrow cavity. (d) Higher magnification (×100). Scale bar: 500 μm.
