Feasibility of using allograft bone with resorbable collagen membrane for alveolar ridge vertical defect augmentation for dental implant placement in Patient with Aggressive Periodontitis: A case report

PURPOSE: This case report demonstrates the feasibility of using allograft bone with a resorbable collagen membrane to correct an alveolar ridge defect and achieve a highly esthetic restoration. CASE PRESENTATION: A 30-year-old woman with generalized aggressive periodontitis and advanced periodontal vertical bone loss in periodontally hopeless upper left right premolar which required a fixed restoration. A staged surgical strategy was devised. First, a resorbable collagen membrane and allograft bone grafts were used to guide bone regeneration in the vertical alveolar defect. After 6 months, complete bone regeneration was achieved and the dental implants were submerged in the bone. Three months later, the implants were exposed and subsequently restored with a crown. CONCLUSION: The vertical guided bone regeneration strategy of using allograft bone and a resorbable collagen membrane has the potential to eliminate the need for additional procedures, which are required with non-resorbable membranes, sinus lift procedures, and extensive block graft procedures.
