Treatment of angular bone defect using flap with GTR membrane and bone graft substitute with 1 year follow up: A case report

Abstract

Aim: The aim of this study was to evaluate the efficacy and the role of a resorbable membrane Guided Tissue Regeneration (GTR) with a bone graft substitute in the management of angular bone defect. Methodology: An angular bone defect of 10 mm was evident between the maxillary second premolar and first molar. After proper 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 the reduction in probing depth. The results were well maintained at the time of last follow- up which was 1 year post-operatively. Conclusion: In this case, where angular defect was associated with localised periodontitis, good results were obtained with bone fill in relation to probing depth reduction. The results were excellent and stable till the last follow up at 1 year. Keywords: Angular defect, Localised Periodontitis, GTR membrane.
