There is considerable controversy regarding optimal choice of the material. An ideal post system should exhibit fracture resistance higher than the average masticatory forces. Finite elemental analysis (FEA) method facilitates precise analysis of the distribution and magnitude of stresses at any point of complex and irregular structures. Thus, this FEA study has been undertaken to evaluate the fracture stress distribution patterns in three fiber posts, viz., carbon, glass fiber, and everStick with an FEA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>The FE stress analysis was performed with the FE software program (CATIA). Three two-dimensional FEA models of central incisor were simulated, and elastic moduli and Poisson's ratio of all the materials were fed to the software. For all the models, a 200 N vertical force was applied on the lingual surface of the tooth at an angle of 45\u00b0. Stress concentration and distribution were evaluated and noted down for all the models. To evaluate the stresses within the restored tooth, the modified von Mises failure criterion was used. The equivalent stresses found in the tested models were compared with the tensile strength of the respective materials. Contact stresses in the luting cement\u2013dentin interface were calculated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Finite element method revealed that maximum stress concentration was at the point of stress application. The stress value was highest in carbon fiber post followed by glass fiber post and least stresses found in everStick post. Maximum stress was observed at the labial surfaces of crown. However, the stress values and distribution were more homogenous in everStick post.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The present findings suggest that everStick post has uniform stress distribution within tooth structure.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/jisppd.jisppd_240_20","type":"journal-article","created":{"date-parts":[[2021,7,28]],"date-time":"2021-07-28T16:12:09Z","timestamp":1627488729000},"page":"178-182","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":10,"title":["Evaluation of stress in three different fiber posts with two-dimensional finite element analysis"],"prefix":"10.4103","volume":"39","author":[{"given":"Dharmaraj Basavaraj","family":"Patil","sequence":"first","affiliation":[{"name":"Department of Pedodontics, Guru Gobind Singh Dental College and Research Center, Burhanpur, Madhya Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E Rajendra","family":"Reddy","sequence":"additional","affiliation":[{"name":"Department of Pedodontics, Kamineni Institute of Dental Sciences, Nalgonda, Telangana, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S Thabitha","family":"Rani","sequence":"additional","affiliation":[{"name":"Department of Pedodontics, Kamineni Institute of Dental Sciences, Nalgonda, Telangana, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Snehal Shivraj","family":"Kadge","sequence":"additional","affiliation":[{"name":"Department of Pedodontics, HKDET Dental College and Hospital, Humnabad, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheetal D","family":"Patil","sequence":"additional","affiliation":[{"name":"General Dentistry, Denta Care Superspecialty Dental Clinic, Gulbarga, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pooja","family":"Madki","sequence":"additional","affiliation":[{"name":"Department of Oral Medicine and Radiology, SB Patil Dental College, Bidar, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2021,7,30]]},"reference":[{"key":"R1-20260302","first-page":"23","article-title":"The carbon fibre post: Metal-free, post-endodontic rehabilitation","volume":"86","author":"Freedman","year":"1996","journal-title":"Oral Health"},{"key":"R2-20260302","first-page":"100","article-title":"Esthetic posts \u2013 An update","volume":"22","author":"Hegde","year":"2010","journal-title":"Endodontology"},{"key":"R3-20260302","first-page":"105","article-title":"Ferrule designs and stress distribution in endodontically treated upper central incisors: 3D finite element analysis","volume":"5","author":"Ahangari","year":"2008","journal-title":"J Dent Tehran Univ Med Sci"},{"key":"R4-20260302","first-page":"255","article-title":"Distribution of stresses in porcelain-fused-to-metal and porcelain jacket crowns","volume":"54","author":"Farah","year":"1975","journal-title":"J Dent Res"},{"key":"R5-20260302","doi-asserted-by":"crossref","first-page":"139","DOI":"10.4103\/0972-4052.29365","article-title":"Effect of the post geometry and material on the stress distribution of restored upper central incisors using 3D finite element models.
