Abstract
This study analyzes the effects of loading a Kennedy class I implant‐assisted removable partial denture (IARPD) using finite element analysis (FEA). Standard RPDs are not originally designed to accommodate a posterior implant load point. The null hypothesis is that the introduction of posteriorly placed implants into an RPD has no effect on the load distribution.

Purpose
<p>This study analyzes the effects of loading a Kennedy class I implant‐assisted removable partial denture (IARPD) using finite element analysis (FEA). Standard RPDs are not originally designed to accommodate a posterior implant load point. The null hypothesis is that the introduction of posteriorly placed implants into an RPD has no effect on the load distribution.</p>
Materials and Methods
<p>A Faro Arm scan was used to extract the geometrical data of a human partially edentulous mandible. A standard plus regular neck (4.8 × 12 mm) Straumann® implant and titanium matrix, tooth roots, and periodontal ligaments were modeled using a combination of reverse engineering in Rapidform XOR2 and solid modeling in Solidworks 2008 FEA program. The model incorporated an RPD and was loaded with a bilateral force of 120 N. ANSYS Workbench 11.0 was used to analyze deformation in the IARPD and elastic strain in the metal framework.</p>
Results
<p>FEA identified that the metal framework developed high strain patterns on the major and minor connectors, and the acrylic was subjected to deformation, which could lead to acrylic fractures. The ideal position of the neutral axis was calculated to be 0.75 mm above the ridge.</p>
Conclusion
<p>A potentially destructive mismatch of strain distribution was identified between the acrylic and metal framework, which could be a factor in the failure of the acrylic. The metal framework showed high strain patterns on the major and minor connectors around the teeth, while the implant components transferred the load directly to the acrylic.</p></abstract><textClass><keywords><term xml:id="jopr12031-kwd-0001">Implant‐assisted removable partial denture</term><term xml:id="jopr12031-kwd-0002">finite element analysis</term><term xml:id="jopr12031-kwd-0003">removable partial denture</term><term xml:id="jopr12031-kwd-0004">dental implant</term></keywords><keywords rend="articleCategory"><term>Original Article</term></keywords><keywords rend="tocHeading1"><term>Original Articles</term></keywords></textClass><langUsage><language ident="en"></language></langUsage></profileDesc></teiHeader></istex:fulltextTEI><json:item><extension>txt</extension><original>false</original><mimetype>text/plain</mimetype><uri>https://api.istex.fr/document/3D99FE801CE47BCB414732B7CB47A88A3B1B93AC/fulltext/txt</uri></json:item></fulltext><metadata><istex:metadataXml wicri:clean="Wiley, elements deleted: body"><istex:xmlDeclaration>version="1.0" encoding="UTF-8" standalone="yes"</istex:xmlDeclaration><istex:document><component version="2.0" type="serialArticle" xml:lang="en" xml:id="JOPR12031"><header><publicationMeta level="product"><doi origin="wiley" registered="yes">10.1111/(ISSN)1532-849X</doi><issn type="print">1059-941X</issn><issn type="electronic">1532-849X</issn><idGroup><id type="product" value="JOPR"></id></idGroup><titleGroup><title type="main" sort="JOURNAL OF PROSTHODONTICS">Journal of Prosthodontics</title><title type="short">Journal of Prosthodontics</title></titleGroup></publicationMeta><publicationMeta level="part" position="10107"><doi>10.1111/jopr.2013.22.issue-7</doi><copyright ownership="thirdParty">© 2013 American College of Prosthodontists</copyright><numberingGroup><numbering type="journalVolume" number="22">22</numbering><numbering type="journalIssue">7</numbering></numberingGroup><coverDate startDate="2013-10">October 2013</coverDate></publicationMeta><publicationMeta level="unit" position="70" type="article" status="forIssue"><doi origin="wiley">10.1111/jopr.12031</doi><idGroup><id type="unit" value="JOPR12031"></id></idGroup><countGroup><count type="pageTotal" number="6"></count></countGroup><titleGroup><title type="articleCategory">Original Article</title><title type="tocHeading1">Original Articles</title></titleGroup><copyright ownership="thirdParty">© 2013 by the American College of Prosthodontists</copyright><eventGroup><event type="manuscriptAccepted" date="2012-12-27"></event><event type="xmlCreated" agent="Aptara" date="2013-02-08"></event><event type="xmlConverted" agent="Converter:WILEY_ML3G_TO_WILEY_ML3GV2 version:3.2.6 mode:FullText" date="2013-10-25"></event><event type="publishedOnlineEarlyUnpaginated" date="2013-04-01"></event><event type="firstOnline" date="2013-04-01"></event><event type="publishedOnlineFinalForm" date="2013-10-25"></event><event type="xmlConverted" agent="Converter:WML3G_To_WML3G version:4.6.4 mode:FullText" date="2015-10-02"></event></eventGroup><numberingGroup><numbering type="pageFirst">550</numbering><numbering type="pageLast">555</numbering></numberingGroup><correspondenceTo>John M.
