Autologous bone chips are widely used in orthopedic surgery to fill large defects due toosteoinductive property but are limited in quantity. Several groups have reported the formation ofmineralized bone after implantation of bioceramics in ectopic sites of different animals. However,osteoinduction by bioceramics has not yet proved to be equivalent to those of autologous bone. Inthis study, we compare the bone inducing capability of autologous bone chips and syntheticbiphasic calcium phosphate (BCP) ceramics granules sintered at various temperatures. Bothmaterials were implanted in muscles and femurs of goats inside hollow containers for 6, 12 and 24weeks and analyzed by histology. This study showed that bone tissue formed in contact with microporous ceramics sintered at low temperature as well as autologous bone chips both in ectopic andintrafemoral sites of goats
