From these, six were elected to be treated with autogenous (AT) bone grafts and six with fresh\u2010frozen bone AL. This last group included the patients who had absence of a convenient amount of bone in donor sites. Each patient received from one to six graft blocks, totalling to 12 ATs and 17 ALs. Seven months after grafting procedures, biopsies of the grafts were made using 2\u2010mm internal diameter trephine burs, and processed for histological analysis. One biopsy was retrieved from each patient.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Clinically, all grafts were found to be firm in consistency and well\u2010incorporated to the receptor bed. Histological analysis showed a large amount of necrotic bone surrounded by few spots of new\u2010formed bone in the AL group, suggesting low rate of graft remodeling. In the AT group, an advanced stage of bone remodeling was seen.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    Human fresh\u2010frozen bone block AL showed clinical compatibility for grafting procedures, although associated to slow remodeling process. Further studies are needed to define, at long term, the remodeling process chronology the clinical longitudinal results for fresh\u2010frozen bone AL.\n
