title: Guided bone regeneration in the treatment of a large periapical lesion: a case report.
abstract: A large (19 mm x 24 mm) periapical lesion associated with tooth #10, perforating both the labial and palatal cortical plates, was treated with decalcified freeze-dried bone allograft and guided bone regeneration. The membranes were removed after a seven-month healing period. Complete osseous reconstruction of the cortical plates was noted. Biopsies demonstrated healing with mature bone and hemopoietic marrow. Few particles of decalcified freeze-dried bone could be observed. Graft particles that remained were surrounded by new bone. The learning objective of this article is to present the regeneration procedure utilized along with the histologic biopsy results to the clinician.
