Cortical Bone Plate Versus Cortico-cancellous Block Graft

Not Applicable

Completed

• Conditions: Horizontal Atrophy of Edentulous Alveolar Ridge
• Interventions: Procedure: Split-block technique; Procedure: Cortico-cancellous block graft

• Registration Number: NCT04567966
• Lead Sponsor: Ain Shams University

Brief 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.

Arm && Interventions

Group	Intervention	Description
Cortical bone plate	Split-block technique	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	Cortico-cancellous block graft	A cortico-cancellous block graft was harvested from the symphysis of the mandible and fixed to the atrophied ridge.

Evaluation of bone quality	4 months	Histomorphometric analysis (Masson's Trichrome stain)

Secondary Outcome Measures

Name	Time	Method
Horizontal ridge dimensional changes	4 months	Measuring the linear horizontal changes using CBCT
