Objectives
<p>This investigation focused on long‐term changes in graft height, implant survival rate, and peri‐implant tissue conditions of dental implants placed in alveolar ridges after augmentation procedures with a follow‐up of 10 years.</p>
Material and methods
<p>We conducted a retrospective cohort study with prospective long‐term follow‐up of 25 patients with edentulous severe atrophic maxillary situations who received a vertical augmentation procedure with autologous bone prior to implant placement. The participants were divided into three groups according to whether they underwent sinus elevation, onlay grafting, or a combination of both techniques. After a four‐month healing period, 127 implants were inserted in the corresponding regions. Following a six‐month healing period, the participants underwent prosthodontic rehabilitation, incorporating a fixed or removable implant denture. The cohort was clinically and radiographically followed up 1, 5, and 10 years after augmentation. The following parameters were measured: radiographic vertical bone changes, implant loss, peri‐implant pocket depth (<hi rend="fc">PD</hi>), width of keratinized mucosa (<hi rend="fc">KM</hi>), sulcus fluid flow rate (<hi rend="fc">SFFR</hi>), and the radiographic distance between the implant shoulder and the first visible bone‐to‐implant contact (<hi rend="fc">DIB</hi>).</p>
Results
<p>Seven implants were lost during the observation period, resulting in a cumulative 10‐year survival rate of 94.48%. Significant bone loss occurred during the first 12 months, after which the resorption slowed down and bone height eventually stabilized. After 10 years, the total vertical bone loss was 27.51% after onlay grafting, 28.14% after sinus elevation, and 30.24% in the combination group, with no statistically significant between‐group differences. Peri‐implant follow‐up examinations revealed a positive correlation between <hi rend="fc">SFFR</hi> and <hi rend="fc">PD</hi>, respectively, <hi rend="fc">DIB</hi>, and a negative correlation between <hi rend="fc">SFFR</hi> and <hi rend="fc">KM</hi>.</p>
Conclusion
<p>The treatment method does not seem to impact vertical bone loss following augmentation using autologous grafts. This approach results in long‐term stability of dental implants. A sufficient width of keratinized peri‐implant mucosa is important to prevent peri‐implant bone loss and inflammation.</p></abstract><textClass><keywords><term xml:id="clr12045-kwd-0001">autologous bone</term><term xml:id="clr12045-kwd-0002">bone augmentation</term><term xml:id="clr12045-kwd-0003">bone resorption</term><term xml:id="clr12045-kwd-0004">dental implant</term><term xml:id="clr12045-kwd-0005">keratinized gingiva</term><term xml:id="clr12045-kwd-0006">onlay bone grafting</term><term xml:id="clr12045-kwd-0007">sinus lift</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="clr12045" 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.
