Three different metallic retainer wires were used for comparison and three tests were performed; two tests measured debonding force and associated wire deflection from acrylic blocks and bovine teeth and one test for pull\u2010out force. To test debonding force, a vertically directed compressive force was applied to the retainer wires bonded to the acrylic blocks and bovine teeth, while for pull\u2010out test; a vertically directed tensile force detached the retainer wire.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In both debonding tests, PEEK wires (regardless the surface treatment) had non\u2010significant difference when compared to each other, or to the other metallic wires, except the dead\u2010soft coaxial wire group. The dead\u2010soft coaxial wire group had significant difference when compared to other groups regarding both the force magnitude and maximum deflection, the only exception was the debonding force of the flat braided retainer wires bonded to bovine teeth. In pull\u2010out test PEEK wires conditioned with adhesive system and the air\u2010abraded recorded the second and third highest readings respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Within the limitations of this study, the 0.8\u2009mm round PEEK wires have comparable performance\u2014in terms of debonding and pull out forces\u2014to conventional retainers when bonded with 4\u2009mm composite bonding spots; using air\u2010abrasion for 10\u2009s at 3.5\u2009MPa provided sufficient adhesion of the composite to the wire, and conditioning with adhesive system may provide no further clinical benefit.<\/jats:p><\/jats:sec>","DOI":"10.1002\/cre2.377","type":"journal-article","created":{"date-parts":[[2020,12,14]],"date-time":"2020-12-14T07:21:58Z","timestamp":1607930518000},"page":"302-312","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["The efficacy of polyether\u2010ether\u2010ketone wire as a retainer following orthodontic treatment"],"prefix":"10.1002","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0851-560X","authenticated-orcid":false,"given":"Ammar Salim","family":"Kadhum","sequence":"first","affiliation":[{"name":"Orthodontic Department, College of Dentistry University of Baghdad  Baghdad Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akram Faisal","family":"Alhuwaizi","sequence":"additional","affiliation":[{"name":"Orthodontic Department, College of Dentistry University of Baghdad  Baghdad Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,12,13]]},"reference":[{"key":"e_1_2_15_2_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40510-016-0137-x"},{"key":"e_1_2_15_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.dental.2017.01.006"},{"key":"e_1_2_15_4_1","doi-asserted-by":"publisher","DOI":"10.4041\/kjod.2012.42.1.39"},{"key":"e_1_2_15_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0889-5406(95)70085-4"},{"key":"e_1_2_15_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0889-5406(97)70304-4"},{"issue":"1","key":"e_1_2_15_7_1","first-page":"29","article-title":"Orthodontic bonded retainers","volume":"51","author":"Butler J.","year":"2005","journal-title":"Journal of the Irish Dental Association"},{"key":"e_1_2_15_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/jopr.12791"},{"key":"e_1_2_15_9_1","doi-asserted-by":"publisher","DOI":"10.1093\/ejo\/cjq017"},{"issue":"6","key":"e_1_2_15_10_1","first-page":"471","article-title":"Viability of bovine teeth as a substrate in bond strength tests: A systematic review and meta\u2010analysis","volume":"20","author":"De Carvalho M.
