Shell Technique with a Xenogeneic Cortical Bone Lamina and Particulated Bone Graft for Horizontal Ridge Augmentation: A Case Series

The aim of this prospective case series was to evaluate the efficacy and safety of a xenogeneic cortical bone lamina utilized as a “shell” on the buccal aspect of narrow alveolar ridges for horizontal bone augmentation. A total of 15 patients requiring multiple implant restorations at sites with moderate to severe horizontal bone deficiency were consecutively enrolled. Horizontal bone augmentation was performed using a xenogeneic cortical bone lamina (XCBL) that was fixed on the buccal aspect of the
