The concept of Guided Bone Regeneration (GBR) is quite old and is now covering a large quantity of techniques and combinations of grafting materials and resorbable or nonresorbable membranes. For the treatment of the resorbed posterior mandible, the efficiency of the GBR concept is relatively difficult to fully validate, as it remains difficult operatordependent techniques where no consensus on the material combination exists. The terminology used in the literature is quite confusing about these techniques, as it covers in fact many different approaches. In this article, we isolate and describe for the first time one
very specific approach named Screw-Guided Bone Regeneration (S-GBR), where the osteosynthesis screws and/or screw implants are used as pillars of the bone regenerative compartments during GBR strategies. We show that this particular version of GBR in fact covers transversally many techniques of bone grafting and regeneration which have in theory very little in common, particularly the posterior mandible lateral ridge augmentation and the simultaneous sinus-lift and implantation. We also describe one new approach of pure S-GBR for the treatment of the resorbed posterior mandible based on a 5-year experience with this technique using L-PRF (Leukocyte- and Platelet-Rich Fibrin) as healing and interposition material.
