Templates for the attachment bonding were made with 1\u2010mm EVA or 0.5\u2010mm PETG laminates. Orthodontic aligners were manufactured with 0.75\u2010mm PETG. The thermoplastification process was carried out using either vacuum or pressure machines. The positional differences between the virtual and bonded attachments were assessed in the <jats:italic>X<\/jats:italic>, <jats:italic>Y<\/jats:italic> and <jats:italic>Z<\/jats:italic> coordinates. The marginal adaptation between the aligners and the attachments was measured.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Minor inaccuracies in the positioning of the attachments were observed in all combinations of thermoforming machines and plastic laminates used to fabricate the templates, mainly in the superior\u2013inferior (<jats:italic>Z<\/jats:italic>) dimension. PETG performed better than EVA in the anterior region (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). No association was found between thermoplastification machines and the accuracy of the positioning of the attachments (<jats:italic>p<\/jats:italic>\u2009&gt;\u2009.05). While small misadaptations between the aligners and the attachments were observed, the EVA templates performed better than the PETG templates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The inaccuracy of the attachment positioning and the misadaptation of the aligners to the attachments were slight. The vacuum and pressure thermoplastification machines showed no difference in attachment positioning accuracy. The PETG template was better than the EVA template in the anterior region, but the EVA attachments presented a better adaptation to the aligners than the PETG attachments.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ocr.12843","type":"journal-article","created":{"date-parts":[[2024,8,8]],"date-time":"2024-08-08T13:49:56Z","timestamp":1723124996000},"page":"120-130","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Bonding positional accuracy of attachments and marginal adaptation of in\u2010house aligners \u2013 A quality improvement laboratory study"],"prefix":"10.1111","volume":"27","author":[{"given":"Nath\u00e1lia Moraes Carvalho Barreto","family":"Brand\u00e3o","sequence":"first","affiliation":[{"name":"Pontifical Catholic University of Minas Gerais  Belo Horizonte Minas Gerais Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6678-7585","authenticated-orcid":false,"given":"Raiane Machado","family":"Maia","sequence":"additional","affiliation":[{"name":"Pontifical Catholic University of Minas Gerais  Belo Horizonte Minas Gerais Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victor de Morais","family":"Gomes","sequence":"additional","affiliation":[{"name":"Pontifical Catholic University of Minas Gerais  Belo Horizonte Minas Gerais Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolina","family":"Resende","sequence":"additional","affiliation":[{"name":"Department of Dentistry Pontifical Catholic University of Minas Gerais  Belo Horizonte Minas Gerais Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto Nogueira da Gama","family":"Antunes","sequence":"additional","affiliation":[{"name":"Pontifical Catholic University of Minas Gerais  Belo Horizonte Minas Gerais Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1907-9519","authenticated-orcid":false,"given":"Bernardo Quiroga","family":"Souki","sequence":"additional","affiliation":[{"name":"Pontifical Catholic University of Minas Gerais  Belo Horizonte Minas Gerais Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,8,8]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.5152\/TurkJOrthod.2021.21157"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph20054481"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/ma15020533"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00056-019-00204-7"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1155\/2022\/1637594"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00056-018-00167-1"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40510-020-00312-w"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.4041\/kjod.2021.51.2.135"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bioactmat.2022.10.006"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.25259\/JCIS_64_2022"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.2319\/042421-330.1"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjqs-2015-004411"},{"issue":"2","key":"e_1_2_10_14_1","first-page":"90","article-title":"Surface wear of resin composites used for Invisalign\u00ae attachments","volume":"30","author":"Barreda GJ","year":"2017","journal-title":"Acta Odontol Latinoam"},{"key":"e_1_2_10_15_1","volume-title":"Statistical Methods for Medical and Biological Students","author":"Dahlberg G","year":"1940"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ortho.2023.100755"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/ocr.12353"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40510-022-00453-0"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/edt.12337"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2014.08.006"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.4012\/dmj.2013-131"},{"key":"e_1_2_10_22_1","doi-asserted-by":"publisher","DOI":"10.2319\/113015-813.1"},{"key":"e_1_2_10_23_1","doi-asserted-by":"publisher","DOI":"10.3390\/dj8020047"},{"key":"e_1_2_10_24_1","doi-asserted-by":"publisher","DOI":"10.4041\/kjod.2018.48.5.316"},{"key":"e_1_2_10_25_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40510-019-0289-6"},{"key":"e_1_2_10_26_1","doi-asserted-by":"publisher","DOI":"10.1117\/1.JMI.9.3.031509"}],"container-title":["Orthodontics &amp;
