ABSTRACT
Background:
<p>An increased number of publications report that one‐stage surgery and immediate/early loading of dental implants may be a feasible approach for prosthetic reconstruction of the edentate patient. However, little is known about the histologic response to implants subjected to immediate/early loading in patients.</p>
Purpose:
<p>The aim of the present study was to histologically evaluate oxidized titanium implants subjected to loading immediately following surgery or after 2 months of healing and removed after 5 to 9 months loading.</p>
Materials and Methods:
<p>Five patients participated in the study; each had consulted for implant treatment in the posterior mandible and subsequently volunteered to have extra implants inserted for the purpose of histologic research. Nine oxidized titanium implants (Brånemark System® TiUnite™, Nobel Biocare AB, Gothenburg, Sweden) were retrieved after 5 to 9 months in function. Two implants had been loaded the same day, whereas seven implants were loaded after 2 months of healing. Resonance frequency analysis was performed at retrieval on seven implants. Ground sections were prepared for histology and analyzed using light microscopic morphometry.</p>
Results:
<p>Seven and 8.5 mm implants were placed, predominantly in quality 3 and 4 bone. Four implants were straight (Mk III), and five were tapered (Mk IV). All implants were clinically stable at retrieval and showed ISQ values of 65 to 79 with a mean of 71.4 ± 4.4. Eight of the implants were able to be used for histology. A gross histologic examination showed an undisturbed healing of soft and bone tissues with no apparent differences between response to immediately and early loaded implants. Lamellar bone surrounded the implants, and remodeling was evident and more marked near the implant surface. A condensation of bone toward the implant surface was seen; this resulted in a lamina dura‐like structure in trabecular bone. Thin rims of newly formed bone were often seen following the contour of the implant surface. The morphometric measurements showed a mean bone‐to‐implant contact value of 84.2 ± 10.5% and a mean bone area value of 79.1 ± 6.8%. The two immediately loaded implants showed bone‐to‐implant contact and bone area values of 92.9 ± 0.1% and 84.9 ± 0.9%, respectively. The corresponding values for the six early loaded implants were 81.4 ± 10.6% and 77.1 ± 6.8%, respectively.</p>
Conclusions:
<p>The present study demonstrated that oxidized implants subjected to immediate or early loading do integrate with soft and bone tissues in the posterior mandible.</p></abstract><textClass><keywords xml:lang="en"><term xml:id="k1">dental implants</term><term xml:id="k2">early loading</term><term xml:id="k3">histology</term><term xml:id="k4">immediate loading</term><term xml:id="k5">oxidized surface</term></keywords><keywords rend="tocHeading1"><term>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/2B44893C96E0B6197B5FB41812ABDF06383B7C7F/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"><header><publicationMeta level="product"><publisherInfo><publisherName>Blackwell Publishing Ltd</publisherName><publisherLoc>Oxford, UK</publisherLoc></publisherInfo><doi origin="wiley" registered="yes">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><id type="publisherDivision" value="ST"></id></idGroup><titleGroup><title type="main" sort="CLINICAL IMPLANT DENTISTRY RELATED RESEARCH">Clinical Implant Dentistry and Related Research</title></titleGroup></publicationMeta><publicationMeta level="part" position="03000"><doi origin="wiley">10.1111/cid.2003.5.issue-s1</doi><numberingGroup><numbering type="journalVolume" number="5">5</numbering><numbering type="supplement">s1</numbering></numberingGroup><coverDate startDate="2003-03">March 2003</coverDate></publicationMeta><publicationMeta level="unit" type="article" position="0008800" status="forIssue"><doi origin="wiley">10.1111/j.1708-8208.2003.tb00020.x</doi><idGroup><id type="unit" value="CID88"></id></idGroup><countGroup><count type="pageTotal" number="11"></count></countGroup><titleGroup><title type="tocHeading1">ARTICLES</title></titleGroup><eventGroup><event type="firstOnline" date="2006-10-30"></event><event type="publishedOnlineFinalForm" date="2006-10-30"></event><event type="xmlConverted" agent="Converter:BPG_TO_WML3G version:2.3.2 mode:FullText source:HeaderRef result:HeaderRef" date="2010-03-13"></event><event type="xmlConverted" agent="Converter:WILEY_ML3G_TO_WILEY_ML3GV2 version:3.8.8" date="2014-01-15"></event><event type="xmlConverted" agent="Converter:WML3G_To_WML3G version:4.1.7 mode:FullText,remove_FC" date="2014-10-17"></event></eventGroup><numberingGroup><numbering type="pageFirst" number="88">88</numbering><numbering type="pageLast" number="98">98</numbering></numberingGroup><correspondenceTo>Reprint requests: Antonio Rocci, DDS, Viale Benedetto Croce 158, 66100 Chieti, Italy;
