The objective of this work was to compare the stress pattern generated on the root by a computer\u2010aided design and computer\u2010aided manufacturing (CAD\u2010CAM) milled fiberglass post under occlusal load in a photoelastic simulation and to compare its flexural strength (FS) to other types of posts. A total of 15 simulated roots, produced from photoelastic resins, were created using human canine teeth. These specimens were then separated into three distinct groups: Fiber post conventional, which consisted of fiberglass posts; fiber post customizable, which involved prefabricated fiberglass posts anatomized with composite resin; and fiber post CAD\u2010CAM, which utilized CAD\u2010CAM milled fiberglass posts. Following the application of Relyx ARC cement, the posts underwent photoelastic testing using a polariscope and FS testing using a universal testing machine. The data were submitted to analysis of variance (ANOVA) and Tukey\u2019s test at 5% significance level. It was found that the stress was significantly greater (\n                    <jats:italic>p<\/jats:italic>\n                    &lt; 0.05) for the customizable post (246.5\u2009MPa \u00b1 218.7) in comparison to both the conventional (135.8\u2009MPa \u00b1 99.3) and CAD\u2010CAM (136.5\u2009MPa \u00b1 68.4) posts; the latter group exhibited the lowest flexural values (50.8\u2009MPa \u00b1 7.9), which were significantly different from both the conventional group (123.0\u2009MPa \u00b1 26.9) and the customized group (230.3\u2009MPa \u00b1 18.9), which also differed from each other. The modulus of elasticity showed statistical differences (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009 &lt; 0.05) among the three different methods: CAD\u2010CAM (0.50\u2009GPa \u00b1 0.06), conventional (1.75\u2009GPa \u00b1 0.13), and custom (3.46\u2009GPa \u00b1 0.19). The FS and elasticity modulus of customized posts were significantly higher than those of CAD\u2010CAM, that exhibited the lowest values. Intermediate values were demonstrated by conventional posts. In comparison, to the customized post, the stress study revealed that conventional and CAD\u2010CAM posts had a lower stress in the apical area and a lower general root stress value; but the cervical stress from CAD\u2010CAM posts were practically twice of conventional and customized posts.\n                  <\/jats:p>","DOI":"10.1155\/ijod\/6298753","type":"journal-article","created":{"date-parts":[[2025,4,26]],"date-time":"2025-04-26T05:25:03Z","timestamp":1745645103000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Flexural Strength and Stress Analysis of CAD\u2010CAM Milled Glass Fiber Post and Core"],"prefix":"10.1155","volume":"2025","author":[{"suffix":"J\u00fanior","given":"Sergio Eduardo Ramos","family":"dos Santos","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8083-3077","authenticated-orcid":false,"given":"Kl\u00edssia Romero","family":"Felizardo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1625-3120","authenticated-orcid":false,"given":"Ricardo Danil","family":"Guiraldo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7915-3207","authenticated-orcid":false,"given":"Sandrine Bittencourt","family":"Berger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6198-7695","authenticated-orcid":false,"given":"Murilo Baena","family":"Lopes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,4,26]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3913(94)90438-3"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bdj.4810278"},{"key":"e_1_2_10_3_2","first-page":"733","article-title":"Biomechanical Considerations for the Restoration of Endodontically Treated Teeth: A Systematic Review of the Literature--Part 1.
