Fifty endodontically treated mandibular first molar teeth were divided into five groups (<jats:italic>n<\/jats:italic> = 10). Endocrowns were obtained from lithium disilicate glass ceramic ingots by heat\u2010press technique (Group e.max Press: GEP), and from feldspathic blocks (Group Cerec: GC), polymer infiltrated ceramic network blocks (Group Enamic: GE), lithium disilicate glass ceramic blocks (Group e.max CAD: GEC), and zirconia\u2010reinforced glass ceramic blocks (Group Suprinity: GS) by CAD\/CAM technique. After thermocycling, marginal adaptation was evaluated under scanning electron microscope at \u00d7200 magnification. The specimens' fracture strengths were tested in universal test machine, and fracture types were evaluated. Statistical analyses were performed with Kruskal\u2013Wallis test. The highest marginal gap value was found in GEP, but no significant differences were determined among the other four groups (<jats:italic>p<\/jats:italic>\u2009&gt;\u2009.05). Significant differences were observed among the groups in terms of fracture strength (<jats:italic>p<\/jats:italic> = .019). The fracture strength values of GEC were significantly higher than GE, GC, and GS (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). Values were not significantly different between the GEC and GEP groups (<jats:italic>p<\/jats:italic>\u2009&gt;\u2009.05). CAD\/CAM endocrowns showed better marginal adaptation than heat\u2010pressed endocrowns. Clinically acceptable marginal gaps were seen in both endocrown types. Both CAD\/CAM and heat\u2010pressed lithium disilicate glass ceramic endocrowns showed higher fracture strength.<\/jats:p>","DOI":"10.1002\/jemt.23586","type":"journal-article","created":{"date-parts":[[2020,9,21]],"date-time":"2020-09-21T03:35:19Z","timestamp":1600659319000},"page":"284-290","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Marginal adaptation and fracture strength of endocrowns manufactured with different restorative materials: <scp>SEM<\/scp> and mechanical evaluation"],"prefix":"10.1002","volume":"84","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6102-4933","authenticated-orcid":false,"given":"Gaye","family":"Sa\u011flam","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry Zonguldak B\u00fclent Ecevit University  Zonguldak Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seda","family":"Cengiz","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry Zonguldak B\u00fclent Ecevit University  Zonguldak Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00d6zg\u00fcl","family":"Karacaer","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry Gazi University  Ankara Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,9,11]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/jopr.12499"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.2341\/11-105-L"},{"issue":"3","key":"e_1_2_8_4_1","first-page":"255","article-title":"Clinical evaluation of adhesively placed Cerec endocrowns after 2\u2009years\u2010\u2010preliminary results","volume":"1","author":"Bindl A.","year":"1999","journal-title":"Journal of Adhesive Dentistry"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1991-7902(09)60016-7"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2013.08.003"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.3390\/ma3010351"},{"issue":"2","key":"e_1_2_8_8_1","first-page":"117","article-title":"Biomechanical considerations for the restoration of endodontically treated teeth: A systematic review of the literature, part II (evaluation of fatigue behavior, interfaces, and in vivo studies)","volume":"39","author":"Dietschi D.","year":"2008","journal-title":"Quintessence International"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/jerd.12486"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.2341\/13-143-L"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.dental.2016.03.013"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpor.2010.07.003"},{"issue":"9","key":"e_1_2_8_13_1","first-page":"702","article-title":"Materials for chairside CAD\/CAM restorations","volume":"31","author":"Fasbinder D.
