This study aimed to compare the dimensional accuracy of a new hydrophilic quadrofunctional vinyl polysiloxane (VPS) and polyether (PE), in combination with different impression techniques (mono-phase single step or dual-phase single step). The reference model simulated a partially edentulous mandible. Stainless-steel precision balls were welded to specific teeth and were used to detect dimensional deviations. Fifteen impressions were made for each of the following four test groups: (1) VPS mono-phase, (2) PE mono-phase, (3) VPS dual-phase, and (4) PE dual-phase. Global accuracy was measured by deviations from the reference model, while local accuracy focused on the trueness and precision of abutment tooth surfaces. Statistical analysis was conducted using ANOVA (\u03b1 = 0.05). All distances were underestimated, with the highest global inaccuracies for the cross-arch distance, ranging from \u221282 \u00b5m to \u2212109 \u00b5m. The abutment tooth surfaces showed excellent local accuracy for all the materials and techniques, with crown surface trueness &lt; 10 \u00b5m and precision &lt; 12 \u00b5m. Inlay surfaces had higher inaccuracies (trueness &lt; 15 \u00b5m, precision &lt; 26 \u00b5m). Within the limitations of this study, all impression materials and techniques can be used to produce models with clinically acceptable accuracy.<\/jats:p>","DOI":"10.3390\/ma17174221","type":"journal-article","created":{"date-parts":[[2024,8,27]],"date-time":"2024-08-27T03:51:06Z","timestamp":1724730666000},"page":"4221","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Dimensional Accuracy of Novel Vinyl Polysiloxane Compared with Polyether Impression Materials: An In Vitro Study"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7168-0942","authenticated-orcid":false,"given":"Moritz","family":"Waldecker","sequence":"first","affiliation":[{"name":"Department of Prosthetic Dentistry, University Hospital Heidelberg, University of Heidelberg, 69120 Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9515-4405","authenticated-orcid":false,"given":"Stefan","family":"Rues","sequence":"additional","affiliation":[{"name":"Department of Prosthetic Dentistry, University Hospital Heidelberg, University of Heidelberg, 69120 Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9719-2018","authenticated-orcid":false,"given":"Peter","family":"Rammelsberg","sequence":"additional","affiliation":[{"name":"Department of Prosthetic Dentistry, University Hospital Heidelberg, University of Heidelberg, 69120 Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8411-8748","authenticated-orcid":false,"given":"Wolfgang","family":"B\u00f6micke","sequence":"additional","affiliation":[{"name":"Department of Prosthetic Dentistry, University Hospital Heidelberg, University of Heidelberg, 69120 Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Yuzbasioglu, E., Kurt, H., Turunc, R., and Bilir, H.
