Decortication Bur with drill stop. 


Perforation of the cortical bone layer has been advocated in GBR, because it was postulated that this increases the vascularity of the wound and releases growth factors and cells with angiogenic and osteogenic potential.1


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.


Thus, there is a consensus in the literature that the recipient bed should be decorticalized, so that there is blood supply to the graft, not forming connective tissue between them.
