Abstract

Clinical assessment of bone-graft healing in the maxillofacial region is generally limited to clinical evaluation, radiographs, and biopsy. Sequential interpretation of osseous repair, more sensitive than with conventional radiography is possible with a non-invasive, non-destructive radionuclide method. Technetium-99m radionuclide bone scan was used in the evaluation of the progress of osteogenic activity in autologous iliac bone graft and freeze-dried bone allograft of dog's mandible. Bone scan was performed at 1wk, 2wk, 4wk, 6wk, and 8wk after grafting. In autologous graft the activity ratio for the graft bone remained greater than that of the host since 2자 after grafting; however, in lyophilized allograft the activity ratio for graft bone was greater than that of the host at 6자 after grafting.
