简要总结
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.

研究组 & 干预措施
Cortical bone plate
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.
干预措施: Split-block technique (Procedure)
Cortico-cancellous block graft
A cortico-cancellous block graft was harvested from the symphysis of the mandible and fixed to the atrophied ridge.
干预措施: Cortico-cancellous block graft (Procedure)
