Cortical Bone Plate Versus Cortico-cancellous Block Graft

Ain Shams University20 enrolled

Overview

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.

SINGLE

Enrollment

Conditions

Horizontal Atrophy of Edentulous Alveolar Ridge

Interventions

Split-block techniquePROCEDURE

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 graftPROCEDURE

Horizontal ridge augmentation using a cortico-cancellous block harvested from the chin of the mandible.
