Occlusal veneers can be an alternative to traditional prosthetic restorations such as crowns, inlays, and onlays. Background: The aim of this study is to assess the fracture resistance of occlusal veneers made of various materials depending on their thickness. Methods: In total, 120 occlusal veneers were examined. The restorations were made of four ceramics: leucite LC (IPS Empress Esthetic), hybrid HC (Vita Enamic), lithium disilicate LDC (IPS e.max Press), and zirconium oxide ZOC (Ceramill Zolid HT). A total of 30 veneers were made of each material, 10 for each of the three thicknesses: 1 mm, 1.5 mm, 2 mm. The restorations were cemented on identical abutments duplicated from the developed phantom tooth 35 (KaVo) with composite cement (All Bond Universal). The samples prepared in this way were subjected to a compressive strength test in a universal testing machine. Statistical analysis of the results was performed. Results: The average fracture resistance of occlusal veneers made of zirconium oxide ceramic was 1086\u20131640 N, of lithium disilicate ceramics 456\u20131044 N, of hybrid ceramics 449\u2013576 N, and of leucite ceramics 257\u2013499 N. Conclusions: Occlusal veneers made of ceramics, zirconium oxide and lithium disilicate, had the highest resistance to fractures. Restorations made of leucite ceramics turned out to be the least resistant to forces. The greater the thickness of the ceramic occlusal veneers, the greater their fracture resistance.<\/jats:p>","DOI":"10.3390\/ma16176006","type":"journal-article","created":{"date-parts":[[2023,9,1]],"date-time":"2023-09-01T09:12:22Z","timestamp":1693559542000},"page":"6006","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Evaluation of Fracture Resistance of Occlusal Veneers Made of Different Types of Materials Depending on Their Thickness"],"prefix":"10.3390","volume":"16","author":[{"given":"\u0141ukasz","family":"Czechowski","sequence":"first","affiliation":[{"name":"Department of Prosthodontics MU of \u0141\u00f3d\u017a, 92-213 \u0141\u00f3d\u017a, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beata","family":"Dejak","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics MU of \u0141\u00f3d\u017a, 92-213 \u0141\u00f3d\u017a, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bart\u0142omiej","family":"Konieczny","sequence":"additional","affiliation":[{"name":"University Laboratory of Materials Research, Medical University of \u0141\u00f3d\u017a, 92-213 \u0141\u00f3d\u017a, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6992-926X","authenticated-orcid":false,"given":"Micha\u0142","family":"Krasowski","sequence":"additional","affiliation":[{"name":"University Laboratory of Materials Research, Medical University of \u0141\u00f3d\u017a, 92-213 \u0141\u00f3d\u017a, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"53","DOI":"10.1016\/j.sdentj.2019.09.004","article-title":"Tooth surface loss: A review of literature","volume":"32","author":"Warreth","year":"2020","journal-title":"Saudi Dent.
