SEM image of SL implant after insertion into bone revealed sharp peaks less prominent or completely removed, resulting in flattened smooth areas after implant insertion (a). Also, the alumina grit-particles (dark and smooth) embedded into the surface (b) were less prevalent after insertion. Along the implantation sites, particles were identified by SEM-BSD (c) and their Ti and Al content was shown by EDS mapping of the surface (d).
