Material and Methods: For corrosion test, castable magnetic attachments containing 39.5% platinum, 59.75% iron and 0.75% niobyum by weight and fabricated magnetic attachment system, Hilop, with neodymium, iron and boron content were immersed in 1% lactic acid and 0,9% NaCI for 14 days (n:8). The released iron, platinum, neodimyum, boron and niobyum ions in the solutions from the samples were examined by inductively coupled plasma mass spectroscopy (ICP-MS) methods. Results: Iron was found the highest released element into the both solutions for all attachment systems and causing corrosion. In addition, castable magnetic attachment system was found to be the most resistant to corrosion in both environments. Conclusion: Coating with stainless steel makes the fabricated magnetic attachment system resistant to corrosion, but the high platinum content made the castable magnets more resistant to corrosion. © 2018 Cumhuriyet University Faculty of Dentistry.en10.7126/cumudj.394767info:eu-repo/semantics/openAccessAttractive Force; Corrosion Resistance; Icp-Ms; Magnetic Attachment; Magnetic Flux DensityArticle2121301352-s2.0-85051654161Q4
