| Abstract: | In this study, we investigated the suppression of metal ion elution on dental orthodontic stainless steel wire. Metal ion elution using Cr and Ni can potentially cause a metal allergy. To suppress metal ion elution from stainless steel wire, three types of surface chemical modifications were carried out. The obtained wire was immersed into several aqueous solutions, and then the eluted ions were determined using coupled plasma mass spectrometry (ICP-MS). By both electropolymerization and self-assembly monolayer formation, the ion elution was effectively reduced. Further, the stainless steel surface was modified using a polyamine, renowned for its antibacterial properties. This surface modification indicated a metal ion suppression effect. These results suggested that these surface modifications succeeded in suppressing the metal ions. |
