Anterior Maxilla With Deficient Ridge Height and/or Width Clinical Trial
Official title:
Vertical and Horizontal Alveolar Ridge Augmentation Using Autogenous Onlay Ring Blocks Combined With Simultaneous Guided Bone Regeneration Using Native Collagen Membrane in Atrophic Anterior Maxilla.
Many different techniques exist for effective vertical bone augmentation, such as the use of particulate bone grafts and bone graft substitutes, barrier membranes for guided bone regeneration (GBR), autogenous and allogenic block grafts, and the application of distraction osteogenesis. Harvesting of autogenous block grafts is associated with greater morbidity compared with the less invasive procedure of using autogenous particles harvested through bone scrapers. On the other hand, particulate grafts always require a space-maintaining barrier, or their physical properties would not allow three-dimensional bone regeneration as those of block grafts do.
