Combined treatment of a large periodontal defect using GTR and DFDBA

The regeneration of periodontal structures lost to inflammatory disease is an elusive yet attainable goal of periodontal therapy. This article reports the successful treatment of a large periodontal defect using a combination of demineralized freeze-dried bone allograft (DFDBA) and guided tissue reg eneration (GTR). The case presents endodontic and mucogingival complication s in the combined GTR osseous graft technique. The combined techniques used in this 27-year-old patient achieved a reduction in probing depth, radiogr aphic evidence of bone fill, and a reduction in clinical mobility.
