However, the accuracy of this method compared with that of traditional impression-making techniques remains uncertain. We therefore decided to evaluate the accuracy of COIM in the context of partially edentulous jaws in an in vivo setting. Twelve partially edentulous patients with different Kennedy classes underwent both a conventional impression (CI) and a computerized optical impression (COI) procedure. The CI was then digitized and compared with the COI data using 3D analysis software. Four different comparison situations were assessed: Whole Jaw (WJ), Mucosa with Residual Teeth (M_RT), Isolated Mucosa (IM), and Isolated Abutment Teeth (AT). Statistical analyses were conducted to evaluate group differences by quantifying the deviation values between the CIs and COIs. The mean deviations between the COIs and CIs varied significantly across the different comparison situations, with mucosal areas showing higher deviations than dental hard tissue. However, no statistically significant difference was found between the maxilla and mandible. Although COIM offers a no-pressure impression method that captures surfaces without irritation, it was found to capture mucosa less accurately than dental hard tissue. This discrepancy can likely be attributed to software algorithms that automatically filter out mobile tissues. Clinically, these findings suggest that caution is required when using COIM for prosthetics involving mucosal tissues as deviations could compromise the fit and longevity of the prosthetic appliance. Further research is warranted to assess the clinical relevance of these deviations.<\/jats:p>","DOI":"10.3390\/jfb14090458","type":"journal-article","created":{"date-parts":[[2023,9,5]],"date-time":"2023-09-05T10:26:43Z","timestamp":1693909603000},"page":"458","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Accuracy of Computerized Optical Impression Making in Fabrication of Removable Dentures for Partially Edentulous Jaws: An In Vivo Feasibility Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2298-3696","authenticated-orcid":false,"given":"Babak","family":"Saravi","sequence":"first","affiliation":[{"name":"Department of Orthopedics and Trauma Surgery, Medical Center\u2014University of Freiburg, Faculty of Medicine, University of Freiburg, Hugstetter Street 55, 79106 Freiburg, Germany"},{"name":"Department of Anesthesiology, Perioperative and Pain Medicine, Brigham and Women\u2019s Hospital, Harvard Medical School, Boston, MA 02215, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julia","family":"Ilbertz","sequence":"additional","affiliation":[{"name":"Department of Prosthetic Dentistry, Medical Center\u2014University of Freiburg, Center for Dental Medicine, Faculty of Medicine, University of Freiburg, Hugstetter Street 55, 79106 Freiburg, Germany"},{"name":"Private Dental Clinic, Am Dorfplatz 3, 78658 Zimmern ob Rottweil, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9278-2203","authenticated-orcid":false,"given":"Kirstin","family":"Vach","sequence":"additional","affiliation":[{"name":"Institute of Medical Biometry and Statistics, Medical Center\u2014University of Freiburg, Faculty of Medicine, University of Freiburg, Stefan-Meier-Str. 26, 79104 Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7095-4190","authenticated-orcid":false,"given":"Ralf J.","family":"Kohal","sequence":"additional","affiliation":[{"name":"Department of Prosthetic Dentistry, Medical Center\u2014University of Freiburg, Center for Dental Medicine, Faculty of Medicine, University of Freiburg, Hugstetter Street 55, 79106 Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1434-5398","authenticated-orcid":false,"given":"Sebastian B.
