A test-model incorporating three implant replicas was customized. A total of forty guides were printed from five printable resins. A group made from a self-curing composite served as control group. The guides were checked for fit. Vertical discrepancies between the model and guides were measured at standardized points at a load of 500 g (P1). The guides were connected to implant replicas and scanned, and their angles were digitally measured. The specimens were sterilized in a steam sterilizer at 121 \u00b0C for 20 min at 2 bar pressure. Vertical discrepancies (P2) and angulations were remeasured. Additionally, the specimens were repositioned with an increased load, and measurements were repeated (P3). All specimens were repositionable after sterilization. The smallest variation in discrepancy at a 500 g load was 428 \u00b5m, whereas the greatest was 1487 \u00b5m. Under an increased force, the smallest change was 94 \u00b5m, while the greatest was 260 \u00b5m. The level of significance \u03b1 = 0.05 (95% confidence interval) was set for all tests. The variation in the measured angles was not statistically significant (Kruskal\u2013Wallis\u2019s test, p &gt; 0.05). The accuracy was affected by the material and sterilization, but it was clinically acceptable when an increased load was applied during repositioning.<\/jats:p>","DOI":"10.3390\/ma16155305","type":"journal-article","created":{"date-parts":[[2023,7,28]],"date-time":"2023-07-28T07:58:52Z","timestamp":1690531132000},"page":"5305","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["The Effect of Sterilization on the Accuracy and Fit of 3D-Printed Surgical Guides"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6317-994X","authenticated-orcid":false,"given":"Christine","family":"Yazigi","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, Propaedeutics and Dental Materials, School of Dentistry, Christian-Albrechts University, 24105 Kiel, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
