Evaluation of Anterior Alveolar Ridge Reconstruction with Allogenic Bone Plate and Autogenous Cortical Bone Chips: A Radiographic and Histological Clinical Study.

Abstract

Localized alveolar bone defects can be treated with various augmentation techniques and grafting materials. The reconstruction of alveolar defects with autogenous bone block graft is the gold standard. The mandibular bone blocks consist primarily of cortical bone and low percentage of cancellous bone, so are more resistant to early revascularization. In addition to that, the preparation of the recipient site to receive the block graft is an important parameter, as an intimate contact between the block graft to the recipient site is critical in the success of the procedure. Therefore, Khoury made a variation of this technique by splitting the solid bone block into two thinner plates or shells, so more vascular chips can be selected and packed in between the bone shell and the alveolar ridge. However, khoury shell technique has received wide interest since its inception and showed favorable results, the probability of donor site morbidity, intraoperative and postoperative complications is still present as described by Khoury.
