Late secondary autogenous bone grafting in cleft patients comparing mandibular (ectomesenchymal) and iliac crest (mesenchymal) grafts.

A comparative study has been performed between two groups of 25 alveolar cleft patients. The cleft area was restored with mesenchymal (iliac crest) and ectomesenchymal bone (mandibular symphysis). The results are discussed; the mandibular symphysis is a reliable donor site; the ectomesenchymal graft is better incorporated, significantly less resorbed, and the orthodontic treatment postoperatively is not altered.
