Dent. J."],"abstract":"<jats:p>Abstract It evaluated the effect of an internal finishing and polishing protocol, combined with surface treatments, on the fatigue flexural strength and topography of 4YSZ ceramic after CAD\/CAM grinding. Ceramic bars (18\u00d75.2\u00d72.4 mm; IPS e.max ZirCAD MT, Ivoclar) were assigned in six groups (n=15) based on two factors: 'Surface condition' - with (POL) or without (non-POL) internal finishing and polishing using F, FF diamond burs and polishing tips (Optragloss, Ivoclar); and 'Surface treatments' - CTRL (no treatment), AB (air-abrasion with 45 \u00b5m aluminum oxide), or GLZ (glaze spray). Surface roughness was measured, and a cyclic flexural three-point bending fatigue test (20 Hz, 10,000 cycles\/step, step size 25 MPa starting at 75 MPa) was conducted. Fractographic and topographic analyses were also performed. Fatigue data were analyzed by Two-Way ANOVA, Kaplan-Meier, Mantel-Cox (Log-Rank), and Weibull analyses, while roughness data underwent Two-Way ANOVA and Tukey's tests. 'Surface condition' significantly influenced fatigue strength (F=18.38, p&lt;0.05), while 'Surface treatment' and the interaction between factors were not significant (p&gt;0.05). POL groups exhibited higher fatigue behavior than non-POL groups: CTRL (POL vs. non-POL, p = 0.000), AB (POL vs. non-POL, p = 0.049), GLZ (POL vs. non-POL, p = 0.004). Roughness showed POL consistently smoother than non-POL in every comparison: non-POL-CTRL &gt; POL-CTRL, non-POL-AB &gt; POL-AB, and non-POL-GLZ &gt; POL-GLZ. Topographic analysis indicated that air abrasion produced uniform surfaces, while glaze partially filled in defects. Fractures originated from surface defects in tensile regions. Internal finishing and polishing after CAD\/CAM grinding enhance the flexural strength of 4YSZ, with air-abrasion and glaze yielding comparable fatigue performance.<\/jats:p>","DOI":"10.1590\/0103-644020256592","type":"journal-article","created":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T15:06:53Z","timestamp":1765206413000},"source":"Crossref","is-referenced-by-count":1,"title":["Improving fatigue behavior of CAD\/CAM-ground 4YSZ via finishing, polishing, and surface treatments"],"prefix":"10.1590","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-0444-3151","authenticated-orcid":false,"given":"K\u00e9tlin Fagundes","family":"Teixeira","sequence":"first","affiliation":[{"name":"Federal University of Santa Maria,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6576-267X","authenticated-orcid":false,"given":"Luiza Freitas Brum","family":"Souza","sequence":"additional","affiliation":[{"name":"Federal University of Santa Maria,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7702-0013","authenticated-orcid":false,"given":"Pablo Machado","family":"Soares","sequence":"additional","affiliation":[{"name":"Federal University of Santa Maria,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-9383-8897","authenticated-orcid":false,"given":"Renatta Wrasse","family":"Temp","sequence":"additional","affiliation":[{"name":"Federal University of Santa Maria,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3218-8031","authenticated-orcid":false,"given":"Cornelis Johannes","family":"Kleverlaan","sequence":"additional","affiliation":[{"name":"Universiteit van Amsterdam and Vrije Universiteit,  Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5412-3546","authenticated-orcid":false,"given":"Jo\u00e3o Paulo Mendes","family":"Tribst","sequence":"additional","affiliation":[{"name":"Universiteit van Amsterdam and Vrije Universiteit,  Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9077-9067","authenticated-orcid":false,"given":"Gabriel Kalil Rocha","family":"Pereira","sequence":"additional","affiliation":[{"name":"Federal University of Santa Maria,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7203-6924","authenticated-orcid":false,"given":"Luiz Felipe","family":"Valandro","sequence":"additional","affiliation":[{"name":"Federal University of Santa Maria,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7957-0350","authenticated-orcid":false,"given":"Ana Carolina","family":"Cadore-Rodrigues","sequence":"additional","affiliation":[{"name":"Federal University of Santa Maria,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2025]]},"reference":[{"issue":"5","key":"ref1","first-page":"369","article-title":"Three generations of zirconia: From veneered to monolithic","volume":"48","author":"Stawarczyk B","year":"2017","journal-title":"Part I.
