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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Cortical bone plate | Experimental | A cortical plate was harvested from the external oblique ridge and split in half. Then one plate was fixed at a distance from the atrophied ridge and autogenous bone chips were used to fill the gap between the plate and the ridge. |
|
| Cortico-cancellous block graft | Active Comparator | A cortico-cancellous block graft was harvested from the symphysis of the mandible and fixed to the atrophied ridge. |

| Split-block technique | Procedure | 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. |
