To repair bony defects with transplanted bone in the body, fresh autogenous bone is undoubtly. A retrospective study was made of a consecutive patient who underwent mandibular reconstruction with PMCB and allogeneic mandibular crib in November 1996. Free autogenous iliac bone in the form of particulate cancellous bone and marrow was densely packed into the allogenous mandibular crib that was adapted to bridge the mandibular discontinuity defect. Freeze dried allogenous mandibular bone was traded by Wonkwang bone bank. Freeze dried allogenous mandibular bone was used as allogeneic crib carrying the PMCB. This case was undergone successful healing with the formation of a continuous bony union with the remaining mandible. The rate of resorption was assessed by sequeal panoramic radiographs, that is, a day of postoperative period, 3 months of postoperative period, 6 months of postoperative period, 12 months of postoperative period. The mean horizontal dimension of the mandibular defect was 58mm and the mean vertical dimension of the reconstructed segments was 30mm. The bony height reconstructed segments retained about 78% of the bony height of a 1-year period. We estimated that autogenous PMCB grafts and allogenous crib grafts were the most successful and esthetic grafts in mandibular discontinuity reconstruction.
