Methods: Sixty extracted human mandibular premolars were prepared with standardized root canals and allocated into six groups (n = 10) according to post material (glass-fiber, PEEK, PEKK) and luting cement (resin or glass ionomer). PEEK and PEKK posts were CAD-CAM fabricated from prefabricated discs. All specimens underwent thermocycling (6000 cycles, 5\u201355 \u00b0C) prior to pull-out force testing on a universal testing machine, and failure modes were classified as adhesive, cohesive, or mixed. Because variance homogeneity was not satisfied, pull-out force values were logarithmically transformed (Log10) before two-way ANOVA and Bonferroni-adjusted post hoc analyses. Results: Post material (p = 0.026), cement type (p &lt; 0.001), and their interaction (p = 0.012) significantly influenced pull-out force. Under resin cement, no statistically significant differences were detected among glass-fiber, PEEK, and PEKK posts. Under glass ionomer cement, PEEK and PEKK posts demonstrated significantly higher pull-out force than glass-fiber posts. The highest mean pull-out force was observed for glass-fiber posts luted with resin cement. The effect of post material on pull-out force was dependent on the luting cement. PEEK posts luted with resin cement showed no significant difference in pull-out force compared with conventional glass-fiber posts, supporting their potential as an alternative post material. Further studies are needed to evaluate the clinical performance of PEEK posts.<\/jats:p>","DOI":"10.3390\/ma19194041","type":"journal-article","created":{"date-parts":[[2026,9,22]],"date-time":"2026-09-22T10:21:48Z","timestamp":1790072508000},"page":"4041","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Influence of Post Material and Cement Type on the Retention of Prefabricated Posts in Endodontically Treated Teeth"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9403-7407","authenticated-orcid":false,"given":"Damla","family":"G\u00fcne\u015f \u00dcnl\u00fc","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry, Hac\u0131 Bekta\u015f Veli University, 50300 Nev\u015fehir, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"software","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8090-2885","authenticated-orcid":false,"given":"P\u0131nar","family":"Y\u0131ld\u0131z","sequence":"additional","affiliation":[{"name":"Nimet Bayraktar Oral and Dental Health Center, 38050 Kayseri, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"software","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-2080-8148","authenticated-orcid":false,"given":"Zekiye","family":"Ero\u011flu","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry, Hac\u0131 Bekta\u015f Veli University, 50300 Nev\u015fehir, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8898-6710","authenticated-orcid":false,"given":"Esra","family":"Talay \u00c7evlik","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry, Ayd\u0131n Adnan Menderes University, 09100 Ayd\u0131n, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1111\/j.1834-7819.2010.01298.x","article-title":"Current perspectives on post systems: A literature review","volume":"56","author":"Goracci","year":"2011","journal-title":"Aust.
