Purpose
<p>To evaluate 1‐year implant survival and marginal bone loss around implants that support fixed partial dentures loaded immediately or after 3 months, and effects from abutment usage.</p>
Materials and Methods
<p>In this 2005 to 2009 randomized, parallel‐group, clinical trial, 50 partially edentulous patients each received three <hi rend="fc">B</hi>rånemark <hi rend="fc">TiUnite</hi>™ implants (<hi rend="fc">N</hi>obel <hi rend="fc">B</hi>iocare®, <hi rend="fc">G</hi>öteborg, <hi rend="fc">S</hi>weden), mostly in the posterior maxilla. Two implants were fitted with abutments: a <hi rend="fc">TiUnite</hi>™ surface and a machine‐milled surface; the suprastructure was attached directly at implant level for the third implant. After randomized allocation, implants were immediately loaded with a fixed temporary bridge (test group) or left unloaded for 3 months (control group). A permanent fixed suprastructure replaced the temporary bridge after 6 months (test). Hard and soft tissues were examined during pretreatment and surgery plus 2 days, 14 days, 4 weeks, 3 months, and 1 year after surgery.</p>
Results
<p>After 1 year, four implants were lost in the test and two in the control groups (1‐year survival rates of 94.9% [test] and 97.2% [control], with no significant intergroup difference). Resonance frequency analysis values indicated a similar pattern in both groups, with implant stability quotient (<hi rend="fc">ISQ</hi>) reduction between 2 and 4 weeks. The test group had a significantly lower <hi rend="fc">ISQ</hi> than the control group at these appointments. After 1 year, marginal bone losses around the implants were, on average, 1.32 mm (test, standard error of the mean [<hi rend="fc">SEM</hi>] 0.08) and 1.24 mm (control, <hi rend="fc">SEM</hi> 0.08), with no significant intergroup difference. Significantly larger marginal bone loss was observed at implants without abutment compared with implants with abutment.</p>
Conclusions
<p>For both groups, this study showed similar implant survival rates and marginal bone loss. Larger bone loss was found at implants loaded without attached abutments.</p></abstract><textClass><keywords><term xml:id="cid12025-kwd-0001">bone</term><term xml:id="cid12025-kwd-0002">dental implants</term><term xml:id="cid12025-kwd-0003">dental prosthesis</term><term xml:id="cid12025-kwd-0004">jaw disease</term><term xml:id="cid12025-kwd-0005">osseointegration</term><term xml:id="cid12025-kwd-0006">rehabilitation</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="cid12025" 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="08104"><doi>10.1111/cid.2014.16.issue-4</doi><copyright ownership="publisher">Copyright © 2014 Wiley Periodicals, Inc.</copyright><numberingGroup><numbering number="16" type="journalVolume">16</numbering><numbering type="journalIssue">4</numbering></numberingGroup><coverDate startDate="2014-08">August 2014</coverDate></publicationMeta><publicationMeta level="unit" status="forIssue" type="article" position="30"><doi>10.1111/cid.12025</doi><idGroup><id type="unit" value="CID12025"></id></idGroup><countGroup><count number="14" 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="2012-11-26" type="xmlCreated"></event><event date="2013-01-04" type="xmlCorrected"></event><event type="publishedOnlineEarlyUnpaginated" date="2013-01-07"></event><event type="firstOnline" date="2013-01-07"></event><event type="publishedOnlineFinalForm" date="2014-08-23"></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">487</numbering><numbering type="pageLast">500</numbering></numberingGroup><correspondenceTo>Reprint requests: Dr. Catharina Göthberg, P.O.
