Summary

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.

Conditions

  • Anterior Maxilla With Deficient Ridge Height and/or Width

Interventions

DEVICE

autogenous ring blockls with GBR covered by collagen membrane

* A crestal incision is made using No. 15 blade extending over the anterior maxilla, an anterior vertical releasing incision is made and a full mucoperiosteum flaps elevated to provide access to the alveolar ridge and the lateral aspect of the maxilla * Autogenous onlay ring blocks is taken by a trephine bur from the chin area and then fixed by screws to the deficient maxillary alveolar height. * Equally autogenous and xenograft bone particles is packed around the screw to fill the defect area completely. * The collagen membrane is fixed to the alveolar ridge by bone tacks and the mixture of autogenous and xenograft bone is then packed. * The flap will then be closed using interrupted 4/0 resorbable sutures.
