Deficiency in the alveolar ridge may occur from tooth loss, trauma, pathology, or congenital defects. This deficiency can compromise ideal implant placement and long-term treatment outcomes. The ridge deficiency can occur horizontally, vertically, or in combination. Hence, different therapeutic strategies have been developed to regenerate alveolar bone defects, including guided bone regeneration (GBR), block graft, ridge splitting, or distraction osteogenesis.3–8  GBR is a method that provides clinicians with an adequate amount of bone for implant site development and has been used with success in dental practice. However, reconstruction of vertical defects may be more challenging than reconstruction of horizontal defects.10–13  A major challenge in vertical regeneration is the eventual collapse of space resulting from excessive masticatory forces over the membrane and graft materials.14 

To overcome some shortcomings of GBR for reconstruction of vertical bony defects, the use of a...
