Abstract
Various types of techniques increase the volume of the atrophied alveolar ridge are used as bone blocks, ridge splitting, osteoperiostal flap, etc. However, one of the most promising methods to date is the GBR method. The use of bone-substituting materials and isolating membranes gives a reliable and predictable result in dental implantology. Recent studies using the dPTFE (dense polytetrafluoroethylene ) membrane have shown a positive result at the site of regeneration even if the membrane itself is exposed in repaired period. With this type of complication the membrane is removed at a period of 4–6 weeks and replaced with a collagen membrane with subsequent approximation of the edges of the flap by sutures (24, 25). This article shows the possibility of regenerating the bone graft from sole xenogenic material using dPTFE membrane in case wound dehiscence in repaired period but without using the collagen membrane coating step after removing dPTFE and it healing by secondary tension.
