dc.description.abstractAim: Materials used in orthodontic treatment can cause corrosion and\rmetal ion release to the mouth. This study was aimed to examine the\rchanges in the friction coefficients and corrosion resistance of the\rmodified Ni-Ti arch wires.\rMethodology: Our sample consisted of 16 Ni-Ti arch wires (0.016 × 0.022\rinches). Coating bathes involving Ni-Ti, Ni-Ti-Mo, and Ni-Ti-Cr were\rprepared for arch wires coating. New surfaces were analyzed by Scanning\rElectron Microscope (SEM), and the crystallographic structure was\rdetermined by X-rays. The friction coefficient of the coated wires was\rdetermined by nanoindentation. Artificial saliva was prepared as a\rcorrosive condition. Impedance measurements were performed with an\relectrochemical analyzer. The AC impedance spectroscopy measurements\rwere performed after 4 hours, 7, 15, 30, 45, and 60 days.\rResults: All groups were more resistant than the control group (-447 mV)\r[group 1 (-388 mV), group 2 (-328 mV), group 3 (-327 mV), group 4 (-427\rmV), group 5 (-395 mV), group 6 (-366 mV), and group 7 (-380 mV)]. Friction\rcoefficients of group 5 (0.252) and group 6 (0.265) were observed to be\rlower than those of the control group (0.288).\rConclusion: In the results of our study, it was shown that the surface\rproperties of Ni-Ti wires could be electrochemically improved. The coated\rwires (group 5 and group 6) had a remarkable corrosion resistance and\rreduced friction. The protocols that we used should help provide betterquality surfaces.en_US
