Brief 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.
Detailed Description:
An autogenous ring block is harvested from the chin area by trephine bur and the autogenous bone chips will be collected with a bone scraper, then a specially manufactured machine titanium tenting screw is used to fasten the ring block to the alveolar ridge. Two or three ring blocks is screwed according to the defect. Then resorbable collagen membrane is fixed to the alveolar ridge instead of the titanium-reinforced e-PTFE and equally autogenous and xenograft bone particles is packed around the screw to fill the defect area completely. Extreme care is taken to avoid autogenous particles drifting distally toward the area of the block. The barrier membrane was then closed over the block and particulate graft and fixed by bone tacks. Then periosteal releasing incision is done to allow tension free adaption of the mucoperisteal flap.
