One-Piece Zirconia Ceramic versus Titanium Implants in the Jaw and Femur of a Sheep Model: A Pilot Study

Figure 6

Histology images of sheep femur under light microscope after 12 weeks of healing. (a) Titanium implant at 2x. (b) Titanium implant at 4x. (c) Zirconia implant at 2x. (d) Zirconia implant at 4x. Old bone (OB), mineralized. New bone (NB), unmineralized bone. Arrows represent the lining of osteoblast cells with osteogenic potential. Immediately following the deposition of osteoid, multinucleated osteoblasts commence the remodelling process and the formation of Haversian system. Osteons (red asterisks) represent the structural end result of a focus of bone remodelling. Black asterisks represent hematopoietic and fatty marrow. Haversian canals (HC) enclosing vascular structures, nerves, and lining cells. Dense bone with high BIC can be seen in (d). Scale bar: 100 μm.
