Twenty\u2010five (25) milligrams of bone from each of the banks was implanted into the hindquarter muscles of athymic mice. Two samples from each of the banks were compared with samples from the other banks. A total of 16 implants were grafted into 8 mice. Two additional mice served as controls. One mouse received an implantation of deactived human cortical bone matrix (DBM) (negative control). The other mouse received an implant of human bone morphogenetic protein\/non\u2010collagenous proteins (hBMP\/NCP) infused to surface demineralized human cortical bone (positive control). At 21 days the mice were killed, the hindquarters were photographed, and the tissues were prepared for histologic evaluation. Of the 16 commercial DFDBA implants, 12 were available for histologic evaluation. There was no radiographie evidence of bone formation for the DFDBA implanted mice or the DBM implants. Small bone ossicles were scarcely visible in the hindquarters of the mouse which received the hBMP\/NCP infused bone. Histomorphometric analysis was used to determine the percentage of new and dead bone. The bone was measured in pixels. The predominant histologic feature of the DFDBA implants was non\u2010vital bone chips with minimal amounts of new bone. The average amount of non\u2010vital bone ranged from 78.4% to 92.5%. There was no evidence of bone formation for the DBM implants. The average amount of bone for the mouse which received hBMP\/NCP was 96%. The results of this pilot study indicate that commercially\u2010available DFDBA induced clinically insignificant amounts of bone. The results of this exploratory study questions the continued use of commercially available DFDBA for bone induction in periodontal defects and adjacent to dental implants. The research points out the need for a matrix supplemented with recombinant human BMP (rhBMP). <jats:italic>J Periodontol 1995;66:822\u2013828<\/jats:italic>.<\/jats:p>","DOI":"10.1902\/jop.1995.66.9.822","type":"journal-article","created":{"date-parts":[[2012,3,20]],"date-time":"2012-03-20T23:07:11Z","timestamp":1332284831000},"page":"822-828","source":"Crossref","is-referenced-by-count":85,"title":["Human Demineralized Freeze\u2010Dried Bone: Inadequate Induced Bone Formation in Athymic Mice.
