Influence of load on the arrangement of hydroxyapatite crystallites at the interface with implants in different animals

At the interface with an implant, bone tends to change its properties, affecting the acceptance of the implant. The preferred orientation of hydroxyapatite Ca₁₀(PO₄)₆(OH)₂ (HAp) crystallites at the bone–implant interface has been measured with the D20 neutron 2-axis diffractometer at the Institut Max von Laue-Paul Langevin, Grenoble. The implant has two faces, one coated with plasma-sprayed HAp.
