Clinical Trial Summary

Horizontal ridge augmentation using either cortical bone plate technique or cortico-cancellous block graft was the aim of the study. Bone quality was analyzed histomorphomterically, and horizontal dimensional changes were assessed using CBCT.

Intervention

Procedure:
• Split-block technique
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.
• Cortico-cancellous block graft
Horizontal ridge augmentation using a cortico-cancellous block harvested from the chin of the mandible.
