The use of dental implants has become a widespread and predictable treatment modality for the restoration of missing teeth and various edentulous cases. It is clear that the use of a regenerative technique with dental implant placement is an important step which assists the process of bone regeneration. As the clinical success of implant therapy is based on osseointegration, defined as the direct anchorage of the implant in the bone tissue without the interposition of fibrous tissue, considerable research has been conducted to promote bone growth. The basic principle of Guided Bone Regeneration (GBR) involves the placement of mechanical barriers to protect blood clots and to isolate the bone defect from the surrounding connective tissue, thus providing bone-forming cells with access to a secluded space intended for bone regeneration. The use of GBR to treat bony defects around dental implants has been extensively documented throughout the past decades and among all the available non resorbable barrier membranes used for GBR procedures, membranes made of e-PTFE have become the membrane of choice in many clinical situations. Data reported in the literature seem to demonstrate that GBR procedures are a reliable means for augmenting bone in cases of vertical and/or horizontal defects in partially edentulous patients. These data suggest that GBR should be considered a reliable technique for obtaining bone formation and placing dental implants in cases in which it would otherwise not be possible. This paper reports an overview and a clinical case about the use of GBR in implant surgery.

Based on our result, combined with the information already available in the literature, we may state that GBR is a safe and effective technique for obtaining bone formation and placing dental implants in cases in which it would otherwise not be possible, even if an ideal membrane for treatment is not yet established.
