Abstract(s)

Although the best results in bone grafting have been achieved with autogeneuos bone tissue, allografts and xenografts have been widely used either in mineralized, demineralized, or calcined forms. Demineralized bone has been proven to stimulate new bone formation by exposing, proteins and growth factors necessary for osteoinduction. On the other hand, calcined bone offers a natural architectural mineralized matrix, not present in synthetic apatite materials, as well as an excellent source of calcium. Despite the extensive use and importance of these materials, systematic works regarding their characterization are relatively scarce.
