However, there is no evidence on the accuracy of CAD\/CAM manufactured orthodontic appliances for this kind of application. This study evaluates trueness and precision provided by different CAM technologies and materials for these appliances. Samples of a standard palatal stimulation plate were manufactured using stereolithography (SLA), direct light processing (DLP) and subtractive manufacturing (SM). The effect of material (for SM) and layer thickness (for DLP) were also investigated. Specimens were digitized with a laboratory scanner (D2000, 3Shape) and analyzed with a 3D inspection software (Geomagic Control X, 3D systems). For quantitative analysis, differences between 3D datasets were measured using root mean square (RMS) error values for trueness and precision. For qualitative analysis, color maps were generated to detect locations of deviations within each sample. SM showed higher trueness and precision than AM technologies. Reducing layer thickness in DLP did not significantly increase accuracy, but prolonged manufacturing time. All materials and technologies met the clinically acceptable range and are appropriate for their use. DLP with 100 \u00b5m layer thickness showed the highest efficiency, obtaining high trueness and precision within the lowest manufacturing time.<\/jats:p>","DOI":"10.3390\/ma14154103","type":"journal-article","created":{"date-parts":[[2021,7,23]],"date-time":"2021-07-23T10:31:44Z","timestamp":1627036304000},"page":"4103","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Accuracy Evaluation of Additively and Subtractively Fabricated Palatal Plate Orthodontic Appliances for Newborns and Infants\u2013An In Vitro Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9618-5016","authenticated-orcid":false,"given":"Maite","family":"Aretxabaleta","sequence":"first","affiliation":[{"name":"Department of Orthodontics in the University Centre of Dentistry, Oral Medicine and Maxillofacial Surgery within the University Hospital T\u00fcbingen, Osianderstr. 2-8, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5487-4251","authenticated-orcid":false,"given":"Alexey","family":"Unkovskiy","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Geriatric Dentistry and Craniomandibular Disorders, Charit\u00e9-Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin, Humboldt-Universit\u00e4t zu Berlin, A\u00dfmannshauser Str. 4-6, 14197 Berlin, Germany"},{"name":"Department of Dental Surgery, Sechenov First Moscow State Medical University, Bolshaya Pirogovskaya Street, 19c1, 119146 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernd","family":"Koos","sequence":"additional","affiliation":[{"name":"Department of Orthodontics in the University Centre of Dentistry, Oral Medicine and Maxillofacial Surgery within the University Hospital T\u00fcbingen, Osianderstr. 2-8, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6830-4869","authenticated-orcid":false,"given":"Sebastian","family":"Spintzyk","sequence":"additional","affiliation":[{"name":"Section Medical Materials Science and Technology, University Hospital T\u00fcbingen, Osianderstr. 2-8, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1645-929X","authenticated-orcid":false,"given":"Alexander B.","family":"Xepapadeas","sequence":"additional","affiliation":[{"name":"Department of Orthodontics in the University Centre of Dentistry, Oral Medicine and Maxillofacial Surgery within the University Hospital T\u00fcbingen, Osianderstr. 2-8, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"534","DOI":"10.1111\/jopr.13161","article-title":"Comparison of the Accuracy of Implant Position Using Surgical Guides Fabricated by Additive and Subtractive Techniques","volume":"29","author":"Henprasert","year":"2020","journal-title":"J.
