Mantenimento del volume crestale postestrattivo preimplantare con materiale alloplastico. Valutazione clinica e istologica

To expect a predictable long-term prognosis and good esthetic results for dental implants a sufficient volume of healthy jaw bone should be present at potential implant recipient sites. The aim of this work is to evaluate the volume maintenance in post-extraction sockets where alloplastic material is used . Computer image analysis on radiographies was performed to measure the horizontal distance between the pre-implantation bone-alloplastic profile and the pre-extraction bone profile. Biopsies made 3 months before implant placement were evaluated. The histologic and clinical results confirm that this procedure can be used for volume post extraction maintenance prior to implant placement
