Treatment of Infrabony Defects in Generalized Periodontitis Stage III Grade C Patients with Guided Tissue Regeneration: Case Reports

Abstract

The application of periodontal regenerative surgery techniques can improve the long- term clinical outcomes of teeth with infrabony defects. Different surgical techniques are recommended for the treatment of infrabony defects. Guided tissue regeneration is an appropriate technique that can be used to treat deep infrabony defects. The success of the combined techniques (barrier membrane plus bone replacement graft) will lead to the healing of the vertical component of bone defect by bone fill and clinical attachment level gain. This case report aims to describe the treatment of Infrabony Defects in stage III, Grade C, generalized periodontitis with guided tissue regeneration. Case I is a 21-year- old female patient who came with complaints of bleeding gums easily over the past year. Patients also complain of bad breath. Clinical examination: 6 mm periodontal pocket and infrabony defect. Case II is a 28-year-old woman who has come with complaints of frequent bleeding gums when brushing her teeth since four years ago. Patients also complain that the molars and anterior teeth of the maxillary and mandibles are mobility. Clinical examination: 6 mm periodontal pocket and infrabony defect. Vertical infrabony defects are formed. Combined regenerative therapy (xenograft with membrane vs platelet-rich fibrin with xenograft and collagen membrane) reduces depth and achieves clinical attachment level and bone gain. The conclusion is that the clinical impact is better seen in the additional application of PRF with xenograft and membrane in treating periodontal infrabony defects than using xenograft and membrane alone
