Federico Brugnami, DDS/James T. Mellonig, DDS, MS

PMID: 10635170
DOI: 10.11607/prd.00.0315

Following endodontic treatment, a large periapical lesion (9.0 mm 3 9.0 mm) at a maxillary central incisor was treated with demineralized freeze-dried bone allograft (DFDBA) using the principles of guided tissue regeneration (GTR). The physical barrier was removed 6 months postsurgical. The cortical alveolar plate was observed to be completely reconstructed. Histologic evaluation demonstrated lamellar bone surrounding DFDBA particles. Radiographic follow-up 1 year posttreatment demonstrated complete resolution of the periapical radiolucency.
