Immunohistochemical Analysis of Reconstructed Sheep Mandibles: Transport Distraction Osteogenesis Versus Autogenous Bone Grafting

The only limitation of the present study was that it evaluated the role of BMP-2, -4, and TGF-β expressions in bone repair process at 3 mo postoperatively. Determination of growth factor expression at more than 1 time point would be ideal in elucidating the role of these factors during bone healing.
