- Perforation of the cortical bone layer in GBR (increases the vascularity of the wound and releases growth factors and cells with angiogenic and osteogenic potential)
- Drilling before tent screw or bone tac placement
According to Buser et al, 1996, the cortical bone in the recipient area must be perforated to allow contact between the medullary space of the host bone and the graft bone, since the success of the graft depends on a good blood supply and revascularization of the same (MISCH & MISCH, 1995; VASCONCELOS AND CARVALHO, 2000). The perforations of the cortical bone, in the recipient bed, induce revascularization resulting in an increase in the influx of osteogenic cells, improving the union of the graft with the recipient area (MISCH, 1996). These additional perforations are performed to supply the vascularization from the displaced periosteum.
