Treatment of a large periapical lesion with loss of labial cortical plate using GTR: a case report.

Author information

Department of Periodontology, Tufts University School of Dental Medicine, Boston, Massachusetts, USA.


Following endodontic treatment, a large periapical lesion (9.0 mm x 9.0 mm) at a maxillary central incisor was treated with demineralized freeze-dried bone allograft (DFDBA) using the principles of guided tissue regeneration. 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.
