Bone destruction due to periodontal disease is one of the factors responsible for loss of teeth. The ultimate goal of periodontal therapy is predictable regeneration of lost periodontal tissue including bone defects. Various bone graft materials have been used for periodontal regeneration, which include autogenous grafts, allografts, xenografts, and synthetically produced ones. Amongst allogenic bone grafts, demineralized freeze-dried bone allograft (DFDBA) is most commonly used. All the bone allografts are osteoconductive, but DFDBA also provide an osteoinductive effect. DFDBA has been successfully used to reconstruct intraosseous periodontal defects and furcation defects. This case report describes the management of an intrabony defect in a maxillary left canine where the osseous defect included loss of buccal wall extending up to the periapical region. This localized periodontitis was successfully treated with periodontal regenerative technique using DFDBAs. DFDBA was used because it contains BMP, which induces new bone formation during the healing process. After 1-year follow-up of treatment, the tooth was functional without any signs and symptoms. Clinical and radiographic changes revealed healthy periodontal support.
