Guided tissue regeneration (GTR), Creating space for regeneration in infra-bony defects.

Periodontal regeneration is the major focus for treatment of periodontitis. The goal of periodontal therapy is to regenerate the periodontal tissues destroyed by the disease process. Present study was carried out to investigate the efficacy of guided tissue regeneration (GTR) membrane in the treatment of deep infrabony defects. A patient with pain and pus discharge in maxillary second molar was presented with pocket probing depth of 8mm and was treated with DFDB allograft covered with GTR membrane and was sutured. It was found that after 6 months of surgical procedure of GTR membrane placement with decalcified freeze dried bone allograft, a reduction of 5mm in pocket probing depth took place, which indicates that the resorbable GTR membrane can be effectively used for the treatment of deep infrabony angular defects.
