Abstract
Atrophy of the alveolar bone is an irreversible multifactorial phenomenon, the rate of which varies between individuals and between the jaws. This atrophy of the alveolar ridges presents severe limitations for the oral rehabilitation of the edentulous patients and poses a clinical challenge to the prosthodontists and implant surgeons. The present research aimed to investigate whether the median‐palate of elderly edentulous subjects is anatomically suitable for implant placement.

Introduction
<p>Atrophy of the alveolar bone is an irreversible multifactorial phenomenon, the rate of which varies between individuals and between the jaws. This atrophy of the alveolar ridges presents severe limitations for the oral rehabilitation of the edentulous patients and poses a clinical challenge to the prosthodontists and implant surgeons. The present research aimed to investigate whether the median‐palate of elderly edentulous subjects is anatomically suitable for implant placement.</p>
Materials and methods
<p>A total of 32 samples were harvested from the maxillae of 16 human cadavers. One dentate male subject was included for contrast. Bone quality and quantity were analysed at two regions: the median‐palate and the edentulous maxillary alveolar ridge. Samples were scanned through micro‐<hi rend="fc">CT</hi>, and the region of analysis (<hi rend="fc">ROA</hi>) identified and dissected. Bone volume to tissue volume ratio (%<hi rend="fc">BV</hi>/<hi rend="fc">TV</hi>), trabecular thickness (<hi rend="fc">T</hi>b.<hi rend="fc">T</hi>h), trabecular number (<hi rend="fc">T</hi>b.<hi rend="fc">N</hi>), trabecular separation (<hi rend="fc">T</hi>b.<hi rend="fc">S</hi>p) and trabecular bone pattern factor (<hi rend="fc">T</hi>b.<hi rend="fc">P</hi>f) were evaluated for the two regions using Skyscan <hi rend="fc">CTA</hi>n<hi rend="superscript">®</hi>.</p>
Results
<p>The results of bone volume fraction obtained from <hi rend="fc">CTA</hi>n<hi rend="superscript">®</hi> of the median‐palatal region show higher values than the respective premolar sites in 12 of 15 (80%) edentulous samples. However, this difference was statistically non‐significant (<hi rend="italic">P </hi>=<hi rend="italic"> </hi>0.06). Similarly, the trabecular number for 10 of 15 samples (66.6%) from the median‐palate shows greater values than the respective premolar site (<hi rend="italic">P </hi>=<hi rend="italic"> </hi>0.07). Trabecular thickness of 10 of 15 (66.6%) premolar samples is larger than in the median‐palatal region. However, these differences were also statistically non‐significant (<hi rend="italic">P </hi>=<hi rend="italic"> </hi>0.25). Statistically significant difference (<hi rend="italic">P </hi>=<hi rend="italic"> </hi>0.04) was found between the <hi rend="fc">T</hi>b.<hi rend="fc">S</hi>p values of the two regions.</p>
Conclusion
<p>The results indicate that the anterior median‐palate is structurally better than their respective maxillary premolar region in elderly edentulous persons, and an implant can be placed to anchor an overdenture. The best site for a wide‐body implant was established to be 6–8 mm posterior to the incisive foramen in elderly edentulous patients.</p></abstract><textClass><keywords><term xml:id="clr12050-kwd-0001">bone micro‐architecture</term><term xml:id="clr12050-kwd-0002">bone resorption</term><term xml:id="clr12050-kwd-0003">complete edentulism</term><term xml:id="clr12050-kwd-0004">implant overdenture</term><term xml:id="clr12050-kwd-0005">median‐palatal region</term><term xml:id="clr12050-kwd-0006">micro‐<hi rend="fc">CT</hi></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="clr12050" 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.
