An overview of the constraints related to this roughness parameter is highlighted in this study. This research introduces new parameters for accessing a functional analysis of surface roughness. (2) Materials and Methods: Five samples of CAD\/CAM 3D-printed acrylic resins were prepared. Two polishing techniques, manual and mechanical, were applied. Surface roughness parameters were extracted from a profilometer reading: arithmetic mean height (Ra and Pa), skewness (Rsk and Psk), and kurtosis (Rku and Pku). (3) Results: Significant differences (p &lt; 0.001) were found in the Ra distribution among the study samples, in contrast with the lack of significance in Pa values. Surface roughness parameters revealed an increased coefficient of variance (CV) value due to mechanized polishing across the specimens analyzed. Skewness and kurtosis indicate a more pronounced distribution with the manual polishing technique. (4) Conclusion: This preliminary study exhibits the influence of different polishing protocols on surface roughness parameters. The primary profile, skewness, and kurtosis should be assessed for the surface characterization of acrylic resins.<\/jats:p>","DOI":"10.3390\/app14020619","type":"journal-article","created":{"date-parts":[[2024,1,11]],"date-time":"2024-01-11T05:24:12Z","timestamp":1704950652000},"page":"619","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A Different Approach to Analyzing the Surface Roughness of Prosthetic Dental Acrylic Resins"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5906-0014","authenticated-orcid":false,"given":"Margarida Martins","family":"Quezada","sequence":"first","affiliation":[{"name":"Centre for Interdisciplinary Research in Health (CIIS), Faculty of Dental Medicine, Universidade Cat\u00f3lica Portuguesa, 3504-505 Viseu, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4249-2352","authenticated-orcid":false,"given":"Carlos","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Faculty of Engineering (FEUP), Universidade do Porto, 4099-002 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3936-6539","authenticated-orcid":false,"given":"Javier","family":"Montero","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Department of Surgery, University of Salamanca, 37008 Salamanca, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0119-9790","authenticated-orcid":false,"given":"Andr\u00e9","family":"Correia","sequence":"additional","affiliation":[{"name":"Centre for Interdisciplinary Research in Health (CIIS), Faculty of Dental Medicine, Universidade Cat\u00f3lica Portuguesa, 3504-505 Viseu, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9134-6688","authenticated-orcid":false,"given":"Helena","family":"Salgado","sequence":"additional","affiliation":[{"name":"Centre for Interdisciplinary Research in Health (CIIS), Faculty of Dental Medicine, Universidade Cat\u00f3lica Portuguesa, 3504-505 Viseu, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1500-8465","authenticated-orcid":false,"given":"Patr\u00edcia","family":"Fonseca","sequence":"additional","affiliation":[{"name":"Centre for Interdisciplinary Research in Health (CIIS), Faculty of Dental Medicine, Universidade Cat\u00f3lica Portuguesa, 3504-505 Viseu, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Quezada, M.M., Salgado, H., Correia, A., Fernandes, C., and Fonseca, P.
