摘要

目的:正畸治疗中使用的材料会引起腐蚀和金属离子释放到口腔中。本研究旨在研究改性镍钛拱丝的摩擦系数和耐蚀性的变化。方法:我们的样品由16根镍钛弓丝(0.016 × 0.022英寸)组成。制备了含Ni-Ti、Ni-Ti- mo和Ni-Ti- cr的拱形丝涂层镀液。用扫描电镜分析了新表面,并用x射线测定了晶体结构。采用纳米压痕法测定涂覆金属丝的摩擦系数。在腐蚀条件下制备了人工唾液。阻抗测量用电化学分析仪进行。交流阻抗谱测量分别在4小时、7天、15天、30天、45天和60天后进行。结果:各组耐药程度均高于对照组(-447 mV)[1组(-388 mV)、2组(-328 mV)、3组(-327 mV)、4组(-427 mV)、5组(-395 mV)、6组(-366 mV)、7组(-380 mV)]。实验组5(0.252)和实验组6(0.265)的摩擦系数均低于对照组(0.288)。结论:在我们的研究结果中,表明镍钛丝的表面性能可以通过电化学方法得到改善。涂层钢丝(5组和6组)具有显著的耐腐蚀性和减少摩擦。我们使用的协议应该有助于提供质量更好的表面。本文来源:Özyılmaz AT, Bilgiç Zortuk F, Yılmaz H.改性镍钛拱丝表面性能的评价。国际医学杂志,2021;11(增刊1):167-176。https://doi.org/10.5577/intdentres.2021.vol11.suppl1.25语言修改:本手稿中的英语已由至少两名专业编辑检查,他们都是英语母语者。

Evaluation of the surface properties of modified Ni-Ti arch wires
Aim: Materials used in orthodontic treatment can cause corrosion and metal ion release to the mouth. This study was aimed to examine the changes in the friction coefficients and corrosion resistance of the modified Ni-Ti arch wires. Methodology: Our sample consisted of 16 Ni-Ti arch wires (0.016 × 0.022 inches). Coating bathes involving Ni-Ti, Ni-Ti-Mo, and Ni-Ti-Cr were prepared for arch wires coating. New surfaces were analyzed by SEM, and the crystallographic structure was determined by X-rays. The friction coefficient of the coated wires was determined by nanoindentation. Artificial saliva was prepared as a corrosive condition. Impedance measurements were performed with an electrochemical analyzer. The AC impedance spectroscopy measurements were performed after four hours, seven, 15, 30, 45, and 60 days. Results: All groups were more resistant than the control group (-447 mV) [group 1 (-388 mV), group 2 (-328 mV), group 3 (-327 mV), group 4 (-427 mV), group 5 (-395 mV), group 6 (-366 mV), and group 7 (-380 mV)]. Friction coefficients of group 5 (0.252) and group 6 (0.265) were observed to be lower than those of the control group (0.288). Conclusion: In the results of our study, it was shown that the surface properties of Ni-Ti wires could be electrochemically improved. The coated wires (group 5 and group 6) had a remarkable corrosion resistance and reduced friction. The protocols that we used should help provide better-quality surfaces.   How to cite this article: Özyılmaz AT, Bilgiç Zortuk F, Yılmaz H.
