μmotion affects the peri-implant bone formation . However, no experimental method to measure 3D μmotion along the peri-implant surface has been developed so far, besides uniaxial μmotion in a limited number of sites [2]. This work consists in devising an experimental method to obtain a surface mapping of μmotion (with an accuracy ~ 10μm) along the peri-implant site of a human femoral stem.
