Materials and Methods: Clinical and radiographic data from 437 crowned teeth retained by fiber, metallic, or custom-made posts were collected at Qassim University Dental Hospital between August and November 2025. Biological (secondary caries, periapical lesions) and technical (debonding, fracture, chipping) complications were recorded. Kaplan\u2013Meier and life-table analyses were used to estimate complication-free survival, and Cox regression was employed to identify significant predictors (\u03b1 = 0.05). Results: The mean observation period was 6.76 \u00b1 4.88 years. The overall complication rate was 56.8%. Crowns restored with fiber posts exhibited the lowest complication rate (40.0%) and the highest 15-year cumulative survival (52%), followed by custom-made (38%) and metallic posts (15%). Fiber posts demonstrated a significantly lower hazard of complications than metal posts (HR = 1.70, p = 0.009). Female sex (HR = 1.69, p = 0.001) and mandibular location (HR = 1.36, p = 0.048) were associated with increased risk. Metal\u2013ceramic crowns showed a protective effect compared to ceramic crowns (HR = 0.56, p = 0.001). Conclusions: The type of post significantly affected long-term prognosis of crowned endodontically treated teeth. Fiber posts provided the most favorable outcomes by minimizing catastrophic root fractures, while metallic and custom-made posts demonstrated higher complication hazards. Crown material, arch location, and patient factors further influenced survival outcomes.<\/jats:p>","DOI":"10.3390\/jfb17020084","type":"journal-article","created":{"date-parts":[[2026,2,9]],"date-time":"2026-02-09T14:05:15Z","timestamp":1770645915000},"page":"84","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Clinical Outcomes and Complication Rates of Crown Restorations with Various Endodontic Posts: A Retrospective Analysis"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6929-974X","authenticated-orcid":false,"given":"Ali","family":"Alenezi","sequence":"first","affiliation":[{"name":"Department of Prosthetics Dental Sciences, College of Dentistry, Qassim University, Buraidah 51452, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-8429-9879","authenticated-orcid":false,"given":"Hanin","family":"Alsalhi","sequence":"additional","affiliation":[{"name":"Department of Conservative Dental Sciences, College of Dentistry, Qassim University, Buraidah 51452, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"157","DOI":"10.5395\/rde.2017.42.3.157","article-title":"Survival rates against fracture of endodontically treated posterior teeth restored with full-coverage crowns or resin composite restorations: A systematic review","volume":"42","author":"Suksaphar","year":"2017","journal-title":"Restor.
