Description
Braces wires live in saliva and under stress, and Angelina Stoyanova-Ivanova and seven co-authors watched four kinds corrode in a 2026 study. The wires, stainless steel, two nickel-titanium alloys, and a multiforce variant, were tested fresh, after a week in artificial saliva, and after six to eight weeks in patients' mouths.
Electrochemical tests and electron microscopy told different stories per alloy. Steel's protective film degraded after clinical use. One nickel-titanium specimen turned unstable in the mouth, with pitting corrosion visible on its surface. The copper-bearing alloy changed least between fresh and worn states, hinting at a sturdier surface. The authors map which wires keep their composure in the mouth's chemistry, information orthodontists can use when nickel sensitivity or long treatments raise the stakes.
