Objectives: Guided bone regeneration (GBR) is a widely used technique to augment alveolar ridge defects to allow implant placement and improve the final aesthetic outcomes of implant-supported restorations. Since the introduction of GBR, which is based on the theory of guided tissue regeneration, scientific evidence has demonstrated its effectiveness in regenerating lost bone. A biologically based technique must be used for clinical success and to avoid the occurrence of complications. This article will discuss a step-by-step surgical procedure for GBR using absorbable membrane barrier for ridge augmentation in implants. Materials and Methods: A full-thickness midcrestal incision is made between the teeth preserving the interdental papilla. The required osteotomy is then prepared, the 4.1 × 10 SLA Straumann implant is placed, and good primary stability is achieved. Following implant placement, GBR procedures are performed. A resorbable collagen membrane is then cut to the same shape as the template and placed over the surgical site. Results: The GBR using absorbable membrane barrier for ridge augmentation produces a dense bone, resulting in minimal or no bone loss when implants are placed into this bone. Conclusions: This GBR using absorbable barrier membrane for ridge augmentation in implants had several advantages over other techniques. One advantage is preserving the interdental papilla and providing sufficient advancement of the flap, which are very important for the success of GBR and for the success of implants placed. The second advantage is avoiding of second surgery for the removal of membrane even though the complications using resorbable membrane barrier may have been multifactorial. Therefore, meticulous surgical and restorative procedures are necessary to reduce the prevalence of complications.
