Management of a Circumferential infrabony defect using GTR membrane and bone graft substitute

Aim: The aim of this study was to evaluate the role of a resorbable membrane with a bone graft substitute in the management of a circumferential infrabony defect in a maxillary left first premolar in a patient diagnosed with localised aggressive peri-odontitis. Methodology: A circumferential defect of 5 mm around the maxillary premolar was evident after debridement. The defect was filled up with a bone graft substitute and covered with a resorbable GTR membrane. Results: The site showed significant bony fill at the end of 9 months with reduction in probing depth to normal. The results were well maintained at the time of last followup at 12 months post-operatively. Conclusion: In this case of a circumferential defect associated with localised aggressive periodontitis, excellent results in terms of probing depth reduction and bone fill were obtained. The results were stable till the last followup at 12 months.
