The shape of the mandibles was observed by gross inspection and three-dimensional CT reconstruction.

<p>A: The shape of the mandibles as observed by three-dimensional CT reconstruction showed no resorption of the allogenic mandibular scaffolds in the control group at 48 weeks. The arrow indicate the pores still can be seen in the control group at this time. B: Resorption was observed in the experimental group at 48 weeks. The arrow indicate the resorption. C: The pores still can be seen in the control group at 48 weeks. The arrow indicate the pores still can be seen in the control group at this time. D: The pores were filled with new bone in the experimental group at 48 weeks. The arrow indicate the resorption.
