Figure 2.

Micro‐CT of OCP/Col/TPTDd1.0, OCP/Col/TPTDd0.1, and OCP/Col. In OCP/Col/TPTDd1.0 and OCP/Col/TPTDd0.1, most of the defect is occupied by a radiopaque figure after 4 weeks or more. It increases with time, and repairs the defect. Furthermore, the width of radiopacity is similar to that of original bone. In the OCP/Col group, small radiopaque masses are scattered throughout the defect 4 weeks after implantation. They increase in size and fuse with each other over time.
