A 3-Dimensional Evaluation of Bone Density in Alveolar Cleft Grafting Methods: Bone Substitutes Versus Autologous Bone

Secondary alveolar cleft repair using autologous bone graft is currently the gold standard in treating residual alveolar clefts. Despite its effectiveness, this technique is still burdened by several withdrawals, mostly related to donor site morbidity. To decrease disadvantages for patients, numerous attempts in the literature regarding bone substitutes have been described. The aim of this study is to compare the viability of bovine-based replacement bone material with respect of autologous bone graft in alveolar cleft reconstruction, through 3-dimensional alveolar cleft segmentation and bone density evaluation from preoperative and postoperative cone-beam computed tomography.
