The implant was placed in the bone block to imitate immediate loading, in which a friction coefficient of 0.3 was set between the bone and the implant interface, or delayed loading, where the bone\u2010implant interface was assumed to be perfect. In all models, both a horizontal force (25.5 N) and a 30\u2010degree oblique force (178 N) were applied to the long axis of the implant to the palatal surface of the restoration. The stress distribution was evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>While more stress was observed in the prosthetic structures in the PEEK and PEKK models, the stresses on the implant and bone were similar in all models, regardless of the loading situation. Under immediate loading, PEEK hybrid abutments caused excessive stress accumulation on the titanium base abutment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Even though abutment type did not affect the stresses on peripheral bone, PEEK and PEKK abutments generated greater stresses on the implant and the standard titanium abutment accumulated higher stresses. Oblique forces mostly generated greater stress than horizontal forces. Oblique forces on an immediately loaded implant led to stresses higher than the yield strength of a titanium implant when restored with PEEK hybrid abutment.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jopr.13598","type":"journal-article","created":{"date-parts":[[2022,8,25]],"date-time":"2022-08-25T15:14:20Z","timestamp":1661440460000},"page":"132-138","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Stress behavior of an anterior single implant restored with high\u2010performance polymer abutments under immediate and delayed loading: A 3D FEA study"],"prefix":"10.1111","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3558-3202","authenticated-orcid":false,"given":"Almira Ada","family":"Diken Turksayar","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, Biruni University, Faculty of Dentistry  \u0130stanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3094-7487","authenticated-orcid":false,"given":"Mustafa Borga","family":"Donmez","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, \u0130stinye University, Faculty of Dentistry  \u0130stanbul Turkey"},{"name":"Department of Reconstructive Dentistry and Gerodontology School of Dental Medicine, University of Bern  Bern Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,9,13]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"195","article-title":"Long\u2010term results in placement of screw\u2010type implants in the pterygomaxillary\u2010pyramidal region","volume":"22","author":"Valer\u00f3n JF","year":"2007","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.3233\/BME-181006"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.11607\/jomi.9007"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2014.03.015"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.4103\/njcp.njcp_144_19"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2017.02.017"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/jopr.13415"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1155\/2017\/1373127"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2016.01.022"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1563\/AAID-JOI-D-11-00066"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1067\/mpr.2001.115251"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0229360"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jdent.2008.03.010"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.4103\/0970-9290.70813"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-849X.2010.00654.x"},{"key":"e_1_2_7_17_1","first-page":"607","article-title":"Biomechanical optimization of implant diameter and length for immediate loading: a nonlinear finite element analysis","volume":"22","author":"Kong L","year":"2009","journal-title":"Int J Prosthodont"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10237-018-1038-3"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.msec.2014.02.021"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1155\/2021\/9205930"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0041-1727544"},{"key":"e_1_2_7_22_1","first-page":"961","article-title":"Three\u2010dimensional finite element analysis of titanium and yttrium\u2010stabilized zirconium dioxide abutments and implants","volume":"26","author":"\u00c7aglar A","year":"2011","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.1080\/10255842.2017.1283406"},{"key":"e_1_2_7_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2017.03.008"},{"key":"e_1_2_7_25_1","unstructured":"3D Slicer image computing platform.http:\/\/www.slicer.org.
