摘要: Abstract Proton induced X-ray emission was used for a multi-element analysis of three biomaterials implanted in ovine thighbone: one tri-tricalcic phosphate and two calcium carbonates with different percentages porosity. The proton PIXE method allowed the simultaneous quantification several elements to get profiles concentrations versus implantation delay. We focused on phosphorous which were major bony matrix strontium, trace element characteristic mineralization implants. Concentrations (constitutive CaCO 3 TCP) known differed from concentrations. each sample various times after (1, 3, 6 12 months) by permitted observe evolution concentration Ca, P Sr implant area at interface implant/bone compare implanted.
