Histological analyses.

<p>A: Many inflammatory cells filled in the allogenic mandibular scaffold in the experimental group 4 weeks postoperatively. B: The pores were filled with fibrous tissue in the experimental group at 12 weeks after surgery. C: Most of the transplanted allogeneic bone was replaced by new bone (fibrous ossification) in the experimental group at 48weeks after the reconstruction. D: Allogeneic bone edges showed less absorption in the control group at 4 weeks after surgery. E: The pores could still be seen in the control group at 12 weeks after surgery. F: A small part of the allogenic bone graft was replaced by new bone in the control group at 48 weeks after reconstruction.(IC: inflammatory cell. Po: pore. FB: fibrous ossification. FT: fibrous tissue.)
