Ridge preservation utilizing an acellular dermal allograft and demineralized freeze-dried bone allograft: Part I. A report of 2 cases

Alveolar ridge deformities are usually the result of trauma, periodontal di sease, surgical insult, or developmental defects. Preventing ridge collapse with the extraction of maxillary anterior teeth is vital to an esthetic re storative result. Several techniques are available to prevent ridge collaps e, In these case presentations, ridge preservation was achieved utilizing a n acellular dermal matrix as a barrier membrane with a demineralized freeze -dried bone allograft. This report demonstrated an acceptable esthetic resu lt with no loss of ridge height or width. Soft tissue dimensions were also preserved. The two graft materials were well accepted by the body and heali ng was rapid and without significant discomfort. The technique illustrated provides the surgeon with another option to prevent ridge collapse and ulti mately improve esthetics.
