Abstract

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.
