Purpose
<p>The aim of this study was to evaluate bone remodelling and soft tissue reactions around immediate nonocclusal loaded implants with different collar configuration in beagle dogs.</p>
Material and methods
<p>The mandibular bilateral second, third and fourth premolars of six beagle dogs were extracted. After 3 months of healing, four implants were placed in the mandibles of each dog. Randomly, two implants with a 1.5 mm polished surface collar (<hi rend="fc">TSA</hi>, control group) and two implants with a 0.7 mm polished surface collar and 2.5 mm microthreaded area (<hi rend="fc">TSAA</hi>, test group) were inserted. Both groups were treated with a minimal mucoperiosteal flap elevation approach. Impressions were taken and two single screw‐retained restorations were inserted in each hemi‐mandible 2 days after the implant placement. The animals were sacrificed at 1, 2 and 3 months (two specimens each), and biopsies were obtained. Samples were processed for ground sectioning. Histomorphometric analysis was carried out to compare buccal and lingual bone height loss and soft tissue behaviour between the two groups.</p>
Results
<p>Crestal bone resorption was significantly higher in the control group (<hi rend="italic">P</hi> > 0.05). The establishment of the biological width showed similar outcomes for both groups. Only the distance from the top of the peri‐implant mucosa to the apical portion of the barrier epithelium at lingual aspect was significantly more pronounced in the control group (<hi rend="italic">P</hi> > 0.05).</p>
Conclusions
<p>The alterations that occurred in the peri‐implant tissues were related to the adaptation that occurred after the loading conditions in both groups. The microthread design might have an effect in maintaining the marginal bone loss against loading.</p></abstract><textClass><keywords><term xml:id="clr12047-kwd-0001">collardesign</term><term xml:id="clr12047-kwd-0002">crestal bone</term><term xml:id="clr12047-kwd-0003">immediate loading</term><term xml:id="clr12047-kwd-0004">soft tissue</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="clr12047" 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.

After 3 months of healing, four implants were placed in the mandibles of each dog. Randomly, two implants with a 1.5 mm polished surface collar (TSA, control group) and two implants with a 0.7 mm polished surface collar and 2.5 mm microthreaded area (TSAA, test group) were inserted. Both groups were treated with a minimal mucoperiosteal flap elevation approach. Impressions were taken and two single screw‐retained restorations were inserted in each hemi‐mandible 2 days after the implant placement. The animals were sacrificed at 1, 2 and 3 months (two specimens each), and biopsies were obtained. Samples were processed for ground sectioning. Histomorphometric analysis was carried out to compare buccal and lingual bone height loss and soft tissue behaviour between the two groups.</abstract><abstract>Crestal bone resorption was significantly higher in the control group (P > 0.05). The establishment of the biological width showed similar outcomes for both groups. Only the distance from the top of the peri‐implant mucosa to the apical portion of the barrier epithelium at lingual aspect was significantly more pronounced in the control group (P > 0.05).</abstract><abstract>The alterations that occurred in the peri‐implant tissues were related to the adaptation that occurred after the loading conditions in both groups.
