The apex showed insignificant distal movement in the TLS (<em>P</em> = 0.366) and a significant mesial movement in the RMCR (<em>P</em> = 0.019); the differences between them were significant (<em>P</em> = 0.022).

The development of computer-aided design software, 3-dimensional (3D) printers, surface and volume scanners, and printing resins has had an impact on dentistry and orthodontics. These tools are all already in the armamentarium of the orthodontist, enabling the technological advancement of orthodontic appliances, diagnosis, and treatment. Digital technology has not only helped in the development of the concept of in-office orthodontic laboratories but also allowed the customization of most orthodontic appliances. Orthodontic imaging and analysis software is responsible for gathering all digital data obtained by digital units and the clinical examination. Surface scanners are the key to the entire digital workflow, providing a digital impression in which all appliances will be designed and manufactured. Computer-aided design software is used to design customized appliances that will be manufactured later using 3D printing technology. Metal printing is a technology performed in special laboratories that enables the customization of various metallic appliances but cannot be used in an orthodontic office. All other orthodontic appliances can be designed and manufactured in the orthodontic office, including thermoformed aligners and directly printed aligners. Lately, software advancements have allowed customized lingual and labial orthodontic brackets to be designed and printed in the orthodontic office. To guarantee the security of both patients and orthodontic staff, certain regulations pertaining to the installation of laboratories in orthodontic offices must be developed. In the last few years, orthodontics has made use of artificial intelligence. Nevertheless, artificial intelligence will only be an assistant in orthodontic treatment and will never replace orthodontists.</p></div>","PeriodicalId":72140,"journal":{"name":"AJO-DO clinical companion","volume":"4 1","pages":"Pages 14-25"},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666430523001528/pdfft?md5=9c0d7a021cb0b6b60c9dbbf9cb1419f5&pid=1-s2.0-S2666430523001528-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139023474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
