Research of osteogenesis and angiogenesis of non-vascularized autogenous bone grafts;

Conclusion Non-vacularized ilia can combine well with mandible,but a wide range of mandibular defect isn′t fit for reconstruction by this method.

Vascularized autograft also is used in repairing massive defect in long bones with its advantage of rapid healing to the host bone, but with its insufficient strength the graft is prone to fracture during the early rehabilitation period after operation.
