Results The implants MDI (3M ESPE) and ANEW (Dentatus)showedahomogenousdistributionpat- tern of numerous aluminium oxide particles (Al2 O3 ) as remnants of the blasting process. These alumin- ium oxide particles appear in the material contrast image darker than titanium which can be seen in Figs.2–3and5–6.TheMDIsampleshowedveryrare additionalorganicparticles(10–50 µm),partlywith embedded metal particles (500 nm) containing traces of iron and chromium. The ANEW implant showed up to three organic particles (30–40 µm) and traces of silicon (6–8 µm). The implant ROOTT (TRATE) was the only one-piece implantinthesamplegroupwithnoorganiccontam- inants or inorganic residues (Figs. 8–10, Tab. 3). The blastingmaterialHA/TCPleftnomeasurabletraceson theimplant.Allthreeimplantsasmentionedaboveare madeoftitaniumgrade5,whichisanalloyoftitanium, aluminiumandvanadium.Thehigherconcentrationof aluminium in the elemental analysis of the implants MDI and ANEW (Tab. 1 and 2) is probably a conse- quence of the blasting material, which remains me- chanically interlocked on the implants surface.
