Reconstruction of Alveolar Cleft Using Double Iliac Corticocancellous Blocks in comparison with the gold standard technique ( cancellous bone ) both from anterior iliac crest.
This study will compare two techniques for the proper alveolar cleft reconstruction with adequate bone bridge formation of maximum bone quality, contour, and minimal resorption. One of them is packing autogenous particulate spongy bone from the anterior iliac crest (gold standard). While the other technique would be reconstruction of the cleft with two iliac corticocancellous bone blocks with cancellous bone in between. which benefits of the rapid revascularization and healing of cancellous bone and the strong mechanical properties of cortical bone that will aid in obtaining a proper reconstruction and form for the defect and can be applied to defects of any size.
