摘要

The present study compared the in vivo behavior of an ionic calcium phosphate bone cement and an composite injectable bone substitute (IBS) associating a biphasic calcium phosphate (BCP) mineral Phase and a cellulosic polymer. Three weeks after implantation in rabbit bone, both biomaterials expressed biocompatibility and bioactivity but new bone formation and ceramic degradadation were significantly higher for IBS than for than for the tested ionic cement. With IBS, newly-formed bone developed joining the BCP particles the ones to the others Whereas new bone only grew on the surface of the cement that remained dense with no Obvious degradation 3 weeks after implantation.
