Reconstruction of severe atrophic jaws with Fresh Frized Bone Allografts: clinical histologic and histomorphometric evaluation.

OBJECTIVES Rehabilitation of maxillary edentulism with implant-supported prostheses has come into common clinical practice. Although autologous bone has osteoinductive, osteoconductive and osteogenetic properties, its use is subject to certain disadvantages such as: Increased morbidity Limited amount of bone harvested from each donor site. AIM The aim of this study is to analyze clinical, histological and histomorphometric results of homologous bone for implantoprosthetic rehabilitation in severe atrophic jaws. PATIENTS AND METHODS Twenty consecutive patients, 14 female and 6 males, were treated with homologous bone bank. Treatment protocol consist of: first surgycal step, trasversal and vertical volume restore, second surgycal step: screw remove, specimen biopsy and insert implant fixtures. RESULTS Data show that Fresh Frozen Bone Allografts (FFBA) could be a valuable substitute for autologous bone, in as much as histological and histomorphometric results are widely overlapping. CONCLUSIONS Homologous bone is a valuable option for its large availability with a low cost, good versatility, no morbidity at the donor site, shorter surgical time and hospital stay.
