At present, guided bone regeneration is predominantly applied in the oral cavity to support new hard tissue growth on an alveolar ridge to allow bone augmentation. By using a bioabsorbable or non-resorbable membrane that acts as a barrier to prevent soft-tissue invasion into the defect and forms a chamber to guide the bone regeneration process is used for bone reconstruction. It works on the principle of compartmentalization, allowing osteoblasts to populate the wound site before epithelial and connective tissue cells, thus regenerating bone. In situations with a bone defect at a site, where the primary stability cannot be achieved or when augmentation is not possible in ideal location for subsequent prosthetic therapy, guided bone regeneration prior to implantation represents the method of choice. After attaining primary closure, the wound site is left to heal for 4 to 6 months with non-resorbable barrier membranes along with tenting screws, promising outcomes have been achieved with the majority of bone replacement grafts.
