Abstract
This retrospective study deals with the issue of how to realize the transition from a failing dentition to an implant‐supported prosthesis. The main aim was to assess the reliability of immediate implant and immediate loading (IL) protocols in the edentulous jaws. A further aim was to investigate the role of patient‐related, implant‐related, and surgery‐related secondary variables in the occurrence of implant failure.

Purpose
<p>This retrospective study deals with the issue of how to realize the transition from a failing dentition to an implant‐supported prosthesis. The main aim was to assess the reliability of immediate implant and immediate loading (<hi rend="fc">IL</hi>) protocols in the edentulous jaws. A further aim was to investigate the role of patient‐related, implant‐related, and surgery‐related secondary variables in the occurrence of implant failure.</p>
Materials and Methods
<p>Patients with at least a 4‐year post‐loading follow‐up undergoing the transition from a failing dentition to an implant‐supported prosthesis were retrospectively investigated. Primary variables of implant failure were immediate placement and <hi rend="fc">IL</hi>. Secondary variables were categorized as demographic, anatomic, site, and prosthetically related. Cumulative survival rates (<hi rend="fc">CSR</hi>s) were compared using the <hi rend="fc">K</hi>aplan‐<hi rend="fc">M</hi>eier survival estimate method. Predictors of failure were included in a multivariate <hi rend="fc">C</hi>ox regression model to evaluate the simultaneous effects of multiple covariates and control for correlated observation. Crestal bone loss was also measured at the delayed and the immediately loaded implants.</p>
Results
<p>Five hundred nineteen implants rehabilitating 91 jaws in 80 patients were followed. The <hi rend="fc">K</hi>aplan‐<hi rend="fc">M</hi>eier survival estimate method showed that immediate implant and <hi rend="fc">IL</hi> decreased the <hi rend="fc">CSR</hi> significantly in the maxilla but not in the mandible. Some secondary variables were found to affect the <hi rend="fc">CSR</hi>: maxillary location, age over 70 years, prostheses supported by only immediate implants or a majority of them, temporary cementation, implant diameter, and length. Crestal bone loss was not significantly related to the outcomes.</p>
Conclusions
<p>The present data may provide clinical recommendations to the practitioner treating the transitional patient. In the mandible, the use of immediate implants and <hi rend="fc">IL</hi> does not increase the failure rate. In the maxilla however, combining immediate placement and <hi rend="fc">IL</hi> may significantly increase the failure rate.</p></abstract><textClass><keywords><term xml:id="cid12055-kwd-0001">clinical study</term><term xml:id="cid12055-kwd-0002">delayed implant</term><term xml:id="cid12055-kwd-0003">immediate implant</term><term xml:id="cid12055-kwd-0004">immediate loading</term><term xml:id="cid12055-kwd-0005">post‐extraction site</term><term xml:id="cid12055-kwd-0006">retrospective</term></keywords><keywords rend="tocHeading1"><term>ARTICLES</term></keywords><keywords rend="articleCategory"><term>ARTICLE</term></keywords></textClass><langUsage><language ident="en"></language></langUsage></profileDesc></teiHeader></istex:fulltextTEI></fulltext><metadata><istex:metadataXml wicri:clean="Wiley, elements deleted: body" wicri:toSee="Element #text"><istex:xmlDeclaration>version="1.0" encoding="UTF-8" standalone="yes"</istex:xmlDeclaration><istex:document><component type="serialArticle" version="2.0" xml:id="cid12055" xml:lang="en"><header><publicationMeta level="product"><doi origin="wiley">10.1111/(ISSN)1708-8208</doi><issn type="print">1523-0899</issn><issn type="electronic">1708-8208</issn><idGroup><id type="product" value="CID"></id></idGroup><titleGroup><title sort="CLINICAL IMPLANT DENTISTRY AND RELATED RESEARCH" type="main">Clinical Implant Dentistry and Related Research</title><title type="short">Clinical Implant Dentistry and Related Research</title></titleGroup></publicationMeta><publicationMeta level="part" position="12106"><doi>10.1111/cid.2014.16.issue-6</doi><copyright ownership="publisher">Copyright © 2014 Wiley Periodicals, Inc.</copyright><numberingGroup><numbering number="16" type="journalVolume">16</numbering><numbering type="journalIssue">6</numbering></numberingGroup><coverDate startDate="2014-12">December 2014</coverDate></publicationMeta><publicationMeta level="unit" status="forIssue" type="article" position="140"><doi>10.1111/cid.12055</doi><idGroup><id type="unit" value="CID12055"></id></idGroup><countGroup><count number="10" type="pageTotal"></count></countGroup><titleGroup><title type="tocHeading1">ARTICLES</title><title type="articleCategory">ARTICLE</title></titleGroup><copyright ownership="publisher">© 2013 Wiley Periodicals, Inc.</copyright><eventGroup><event agent="bestset" date="2013-02-21" type="xmlCreated"></event><event type="publishedOnlineEarlyUnpaginated" date="2013-03-18"></event><event type="firstOnline" date="2013-03-18"></event><event type="publishedOnlineFinalForm" date="2014-12-29"></event><event type="xmlConverted" agent="Converter:WML3G_To_WML3G version:4.6.4 mode:FullText" date="2015-10-06"></event></eventGroup><numberingGroup><numbering type="pageFirst">926</numbering><numbering type="pageLast">935</numbering></numberingGroup><correspondenceTo>Reprint requests: Dr. Massimo Del Fabbro, Department of Biomedical, Surgical and Dental Sciences, Istituto Ortopedico Galeazzi, IRCCS, University of Milano, Via R.

The main aim was to assess the reliability of immediate implant and immediate loading (IL) protocols in the edentulous jaws. A further aim was to investigate the role of patient‐related, implant‐related, and surgery‐related secondary variables in the occurrence of implant failure.</abstract><abstract>Patients with at least a 4‐year post‐loading follow‐up undergoing the transition from a failing dentition to an implant‐supported prosthesis were retrospectively investigated. Primary variables of implant failure were immediate placement and IL. Secondary variables were categorized as demographic, anatomic, site, and prosthetically related. Cumulative survival rates (CSRs) were compared using the Kaplan‐Meier survival estimate method. Predictors of failure were included in a multivariate Cox regression model to evaluate the simultaneous effects of multiple covariates and control for correlated observation. Crestal bone loss was also measured at the delayed and the immediately loaded implants.</abstract><abstract>Five hundred nineteen implants rehabilitating 91 jaws in 80 patients were followed.
