Figure 6

A typical appearance of newly formed bone 12 weeks after implantation: (a) ALBO-OS: regular structure of bone beds in new bone; dominant presence of mineralized osteoid; lamellar structure of bone tissue; (b) Bio-Oss: newly formed bone beds which are of irregular structure; amounts of mineralized and unmineralized osteoid which are approximately the same; material particulates which are visible (Masson’s trichrome stain, magnification 40x).
