Methods: Extracted human teeth were mounted on two models and scanned at different times, from 1 h to 2 weeks, with an intraoral scanner (3Shape TRIOS 4) before and after immersion in Monster\u00ae energy drink and tap water. The scans were superimposed (3Shape TRIOS Patient Monitoring, Version 2.2.3.3, 3Shape A\/S, Copengagen, Denmark). Best fit, best-fit tooth comparison, reference best fit using fillings, and palatal rugae as reference points were used for alignment. Surface profile differences were calculated in a cross-section view. The nonparametric Bland\u2013Altman and Kruskal\u2013Wallis tests were used. Results: First, statistically significant differences were marked after 4 days of immersion. The measurements obtained after 2 weeks of immersion were statistically significantly different from the measurements obtained at the different time points until 1 week. No statistically significant differences (p &lt; 0.05) were observed among the alignment methods at any time. Conclusion: In comparison to the best-fit model, both palatal rugae and fillings can be used. The best-fit tooth comparison method is a reliable option; however, it should be used with caution in cases of major surface loss.<\/jats:p>","DOI":"10.3390\/dj12020034","type":"journal-article","created":{"date-parts":[[2024,2,5]],"date-time":"2024-02-05T08:41:43Z","timestamp":1707122503000},"page":"34","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Different Methods of Scan Alignment in Erosive Tooth Wear Measurements: An In Vitro Study"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7611-2795","authenticated-orcid":false,"given":"Nikolaos","family":"Loumprinis","sequence":"first","affiliation":[{"name":"School of Dentistry, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stavroula","family":"Michou","sequence":"additional","affiliation":[{"name":"Department of Odontology, University of Copenhagen, 2200 Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4117-3501","authenticated-orcid":false,"given":"Christos","family":"Rahiotis","sequence":"additional","affiliation":[{"name":"School of Dentistry, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"801","DOI":"10.1007\/s00784-017-2155-6","article-title":"Impact of manual control point selection accuracy on automated surface matching of digital dental models","volume":"22","author":"Becker","year":"2018","journal-title":"Clin.
