Radiographic and Histological Evaluation of Regenerated Bone After Grafting Using Allograft Shell and Autogenous Chips

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

The clinical cases in the present study described the khoury shell technique using an allograft plate and autogenous chips, for horizontal reconstruction of the anterior alveolar ridge in the esthetic zone. Without need to use autogenous bone graft techniques that are characterized by more aggressive surgery.
