Ridge preservation utilizing an acellular dermal allograft and demineralized freeze-dried bone allograft: Part II. Immediate endosseous implant placement

When maxillary anterior teeth are extracted, subsequent ridge collapse can significantly compromise esthetics. Preservation of an adequate volume of b one is vital to successful implant placement. Ridge preservation achieved u tilizing an acellular dermal matrix as a barrier membrane with a deminerali zed freeze-dried bone allograft has been previously reported. In this case presentation, guided bone regeneration was achieved around an immediate end osseous implant when this same technique was used. As in the previous case reports, this technique demonstrated an acceptable esthetic result with vir tually no loss of ridge height or width. Soft tissue dimensions were also p reserved. Both the hard and soft tissue grafts were well accepted by the bo dy and healing was rapid and without significant discomfort. This surgical technique provides the clinician with an option to provide immediate implan t therapy when primary closure cannot be achieved.
