Management of vertical bony defect using novel xenogeneic/allogeneic bone graft: A case report

Abstract

AbstractBackgroundGuided tissue regeneration (GTR) is a common treatment modality for correcting vertical or bony defects in furcations. Multiple materials are used in GTR with allografts and xenografts being the most widely used. Each material has distinctive properties affecting the regenerative potential. A new bone graft combination of xenogeneic/allogeneic may improve the outcome of GTR by providing space maintenance (Xenograft) and osteoinductive potential (Allograft). The aim of this case report is to evaluate the efficacy of the new combined xenogeneic/allogeneic material based on clinical and radiographic outcomes.MethodsA 34‐year‐old healthy male presented with vertical bone loss interproximally between #’s 9 and 10. Clinical exam revealed 8 mm probing depth without mobility. The radiographic exam revealed a wide and deep vertical bony defect of 30%–50% bone loss. The defect was treated using a layering technique with xenogeneic/allogeneic bone graft and collagen membrane.ResultsThe 6‐ and 12‐month follow‐ups revealed a significant reduction in probing depths and radiographic bone fill.ConclusionsGTR using a layering technique of xenogeneic/allogeneic bone graft and collagen membrane showed proper correction of a deep and wide vertical bony defect. The 12‐month follow‐up revealed healthy periodontium with normal probing depths and bone level.
