Ten archwires from five different manufacturers (GAC, 3M, ODS, GC, FOR) were cut into two segments and evaluated using a three-point bending test in accordance with ISO 14841:2006. The center of each segment was deflected to 3.1 mm and then unloaded to 0 N to obtain a load\u2013deflection curve. Deflection at the end of the plateau and forces at 3, 2, 1 and 0.5 mm on the unloading curve were recorded. Plateau slopes were calculated at 2, 1 and 0.5 mm of deflection. Data obtained were statistically analyzed to determine differences (p &lt; 0.001). Results showed that the degree of superelasticity and exerted forces differed significantly among brand groups. After three months of clinical use, FOR released a greater force for a longer activation period. GC, EURO and FOR archwires seemed to lose their mechanical properties. GC wires released more force than other brand wires after clinical use. Regarding superelasticity after sterilization, GAC, 3M and FOR wires recovered their properties, while EURO archwires lost more.<\/jats:p>","DOI":"10.3390\/ma16165604","type":"journal-article","created":{"date-parts":[[2023,8,14]],"date-time":"2023-08-14T10:40:31Z","timestamp":1692009631000},"page":"5604","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Properties of Superelastic Nickel\u2013Titanium Wires after Clinical Use"],"prefix":"10.3390","volume":"16","author":[{"given":"In\u00e9s","family":"Alcaraz","sequence":"first","affiliation":[{"name":"Department of Orthodontics, School of Dentistry, Universitat Internacional de Catalunya, Sant Cugat del Vall\u00e9s, 08195 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9854-8167","authenticated-orcid":false,"given":"Javier","family":"Moyano","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, School of Dentistry, Universitat Internacional de Catalunya, Sant Cugat del Vall\u00e9s, 08195 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ariadna","family":"P\u00e0mies","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, School of Dentistry, Universitat Internacional de Catalunya, Sant Cugat del Vall\u00e9s, 08195 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guillem","family":"Ruiz","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, School of Dentistry, Universitat Internacional de Catalunya, Sant Cugat del Vall\u00e9s, 08195 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Montserrat","family":"Art\u00e9s","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, School of Dentistry, Universitat Internacional de Catalunya, Sant Cugat del Vall\u00e9s, 08195 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6824-1412","authenticated-orcid":false,"given":"Javier","family":"Gil","sequence":"additional","affiliation":[{"name":"Bioengineering Institute of Technology, Facultad de Medicina y Ciencias de la Salud, c\/Josep Trueta s7N, Sant Cugat del Vall\u00e9s, 08195 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7527-8619","authenticated-orcid":false,"given":"Andreu","family":"Puigdollers","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, School of Dentistry, Universitat Internacional de Catalunya, Sant Cugat del Vall\u00e9s, 08195 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,13]]},"reference":[{"key":"ref_1","first-page":"32","article-title":"An Overview of Orthodontic Wires","volume":"28","author":"Kotha","year":"2014","journal-title":"Trends Biomater.
