Clear aligner therapy (CAT) is frequently prescribed for the management of malocclusion. The aim of this review was to collate and synthesize the literature concerning the quality of information (QOI) regarding CAT on the internet. This scoping review was carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. Eighteen studies were identified for inclusion following a systematic search of four databases and screening of publications by two independent reviewers. Most studies (<em>n</em> = 13) evaluated the QOI on social media platforms (SMPs) with five studies determining the QOI of website content. YouTube was the SMP through which relevant communicated information was most assessed. There was considerable variance in the methodologies employed to determine the QOI in the studies. The QOI related to CAT was generally poor-to-moderate on the internet. Poor QOI was a finding related to direct-to-consumer aligners. Details regarding high- and low-quality information were limited. Where documented, high-quality items included benefits of treatment and low-quality items included quality-of-life issues. Evaluation of content in the English language only was a self-reported limitation of the authors of many studies and therefore, a limitation of the present review. Several studies advised that clinicians should be aware of pertinent content communicated through SMPs.</div></div>","PeriodicalId":48688,"journal":{"name":"Seminars in Orthodontics","volume":"32 1","pages":"Pages 75-84"},"PeriodicalIF":2.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146081427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose and describe an alternative approach: a modular orthodontic system based on skeletal anchorage, designed to perform multiple movements within a single framework.
