Abstract
Metal ion elution, including Cr and Ni from dental orthodontic stainless steel, accounts for some allergies. In this study, a self-assembled monolayer (SAM) on a wire surface is proposed for suppressing such elution. This method involves modifying the stainless steel surface using phosphonic acid containing a long alkyl chain. The uncoated and coated wires are immersed in different acidic solutions, and the supernatant is analyzed by inductively coupled plasma mass spectrometry after 1–4 weeks. The results reveal that Cr and Ni ion elution is significantly suppressed by SAM modification. These findings will help in minimizing potential allergens from dental orthodontics.
Highlights
Chemical modifications, such as an organic monolayer formation, are simple and useful methods for enhancing metal and alloy surface functions [1,2,3,4]
We initially investigated chemical modifications on dental orthodontic stainless steel wire surfaces and subsequently evaluated their metal ion elution suppression
The contact angles for the stainless steel substrate before and after self-assembled monolayer (SAM) formation are depicted in Generally, the mechanism of SAM formation has been proposed [22] as illustrated in Scheme 2
Summary
Chemical modifications, such as an organic monolayer formation, are simple and useful methods for enhancing metal and alloy surface functions [1,2,3,4]. These methods have been involved in studies on several fields, including nanoelectronics [5], optoelectronics [6], chemical and biochemical sensing [7], bioengineering [8], life sciences [9], and biomedical applications [10]. Stainless steel is a material routinely used in many applications in different fields It is a biomaterial with a bioacceptable property. Stainless steel exhibits lower corrosion tolerance compared with Ti, Ti alloys, or other dental alloys, it displays excellent mechanical properties, especially in orthodontics [11]
