Keywords
Allograft, Autogenous chips, Horizontal augmentation, Khoury shell technique
Brief summary
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.
Interventions

Intervention model description
Reconstruction of the localized deficient anterior maxilla using an allograft cortical bone plate, which was fixed at a distance from the alveolar ridge using two micro-screws, and the created gap between the allograft plate and the alveolar ridge was filled with autogenous cortical bone chips harvested intraorally using a bone scrapper.
