摘要：

In vivo behavior of biomaterial is dependent on the site of implantation. Characterization by atomic element transfers versus the implantation duration is a quantitative approach to the phenomenon. Here, bioactive coral is implanted in ovine, porcine and rabbit thighbones and not in sheep jawbones as previously reported. Biopsies extracted between 1 and 24 weeks are analysed by fast neutron activation. Mineral composition of the coral is greatly modified: Ca, P, Mg and Sr concentrations become comparable to those of mature bone some months after the implantation. Results suggest a bioactive resorption followed by apatite formation.
