Vertical and Horizontal Bone Augmentation with the Intraoral Autogenous J-Graft – Article

Article By Hassan G. Moghadam, DDS, MSc

Bone defects that arise after dental extraction usually result in both horizontal and vertical bone loss. With time, the soft tissue shrinks concomitantly with the bone, making large augmentations difficult. The current challenge in bone grafting technique is vertical augmentation. The principle reason is the lack of soft tissue to cover the graft and less surface area for revascularization. Therefore, the critical factors in vertical bone grafting are blood supply, surface area, and soft tissue. Significant alveolar bone resorption can occur shortly after dental extractions. In nongrafted sites, more than 20% of the buccal plate is lost after 90 days. Up to 4 mm of vertical height can be lost in the first year. Vertical bone grafting is challenging and has a high complication rate…
