Abstract
It is of imperative clinical significance to define a safe threshold for planned immediate implant restoration. The aim of this report was to evaluate the prognostic accuracy of resonance frequency analysis (RFA) measurements recorded at two different times (implant placement and 8‐week post‐implant placement) and to determine the optimal threshold value for predicting failure risk of immediately restored/loaded implants.

Objectives
<p>It is of imperative clinical significance to define a safe threshold for planned immediate implant restoration. The aim of this report was to evaluate the prognostic accuracy of resonance frequency analysis (<hi rend="fc">RFA</hi>) measurements recorded at two different times (implant placement and 8‐week post‐implant placement) and to determine the optimal threshold value for predicting failure risk of immediately restored/loaded implants.</p>
Material and methods
<p>Twenty‐eight 8‐ or 9‐mm‐diameter implants were placed in either a fresh molar extraction socket or a healed site. An electronic <hi rend="fc">RFA</hi> device was used to record the implant stability quotients (<hi rend="fc">ISQ</hi>s) at implant placement surgery, 8 weeks and 1 year. Receiver operating characteristic (<hi rend="fc">ROC</hi>) analysis was used to identify the optimal cut‐off level. Sensitivity and specificity were also determined at the selected cut‐off value.</p>
Results
<p>The area under the <hi rend="fc">ROC</hi> curve for <hi rend="fc">RFA</hi> at 8 weeks was 0.93 with a significant <hi rend="italic">P</hi>‐value (<hi rend="italic">P</hi> = 0.001). The optimum cut‐off value for detecting implant stability was 60.5 <hi rend="fc">ISQ</hi> measured at 8 weeks, with sensitivity and specificity of 95.2% and 71.4%, respectively.</p>
Conclusions
<p>The implant stability measurements after 8 weeks showed a better accuracy in predicting implants that were at risk of failure than those taken at the time of implant placement.</p></abstract><textClass><keywords><term xml:id="clr12057-kwd-0001">dental implants</term><term xml:id="clr12057-kwd-0002">prognosis</term><term xml:id="clr12057-kwd-0003"><hi rend="fc">ROC</hi> curve</term><term xml:id="clr12057-kwd-0004">sensitivity and specificity</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></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 type="serialArticle" version="2.0" xml:id="clr12057" xml:lang="en"><header><publicationMeta level="product"><doi origin="wiley" registered="yes">10.1111/(ISSN)1600-0501</doi><issn type="print">0905-7161</issn><issn type="electronic">1600-0501</issn><idGroup><id type="product" value="CLR"></id></idGroup><titleGroup><title sort="CLINICAL ORAL IMPLANTS RESEARCH" type="main">Clinical Oral Implants Research</title><title type="short">Clin.
