Cortical Bone Plate Versus Cortico-cancellous Block Graft

Horizontal ridge augmentation using the split-block technique where a cortical bone plate harvested from the external oblique ridge was split in half and fixed at a distance from the atrophied ridge. Then autogenous bone chips were packed in the gap between the plate and the ridge.
