The current proof-of-concept dental technique describes the pathway to construct the non-metal clasp RPD using intraoral scanning and fused filament fabrication (FFF) printing of gingiva-colored polyamide. The present RPD showed acceptable fit and sufficient retention and was considered a valid temporary treatment option. <a href="/1660-4601/18/16/8241">Full article</a> </div> </div> <div class="belongsTo" style="margin-bottom: 10px;"> (This article belongs to the Special Issue <a href=" /journal/ijerph/special_issues/Dentistry_Maxillofacial_Surgery ">New Techniques, Technologies and Materials for Dentistry and Maxillofacial Surgery</a>)<br/> </div> <a href="#" class="abstract-figures-show" data-counterslink = "https://www.mdpi.com/1660-4601/18/16/8241/show" ><span >►</span><span style=" display: none;">▼</span> Show Figures </a><div class="abstract-image-preview "><div class="arrow left-arrow" id="prev607968"><i class="fa fa-caret-left"></i></div><div class="arrow right-arrow" id="next607968"><i class="fa fa-caret-right"></i></div><div class="absgraph cycle-slideshow manual" data-cycle-fx="scrollHorz" data-cycle-timeout="0" data-cycle-next="#next607968" data-cycle-prev="#prev607968" data-cycle-progressive="#images607968" data-cycle-slides=">div" data-cycle-log="false"><div class='openpopupgallery cycle-slide' data-imgindex='0' data-target='article-607968-popup'><span class="helper"></span><img src="data:image/gif;base64,R0lGODlhAQABAAD/ACwAAAAAAQABAAACADs=" data-src="https://pub.mdpi-res.com/ijerph/ijerph-18-08241/article_deploy/html/images/ijerph-18-08241-g001-550.jpg?1628067552" alt="" style="border: 0;"><p>Figure 1</p></div><script id="images607968" type="text/cycle" data-cycle-split="---"><div class='openpopupgallery' data-imgindex='1' data-target='article-607968-popup'><span class="helper"></span><img src='https://pub.mdpi-res.com/ijerph/ijerph-18-08241/article_deploy/html/images/ijerph-18-08241-g002-550.jpg?1628067552'><p>Figure 2</p></div> --- <div class='openpopupgallery' data-imgindex='2' data-target='article-607968-popup'><span class="helper"></span><img src='https://pub.mdpi-res.com/ijerph/ijerph-18-08241/article_deploy/html/images/ijerph-18-08241-g003-550.jpg?1628067552'><p>Figure 3</p></div> --- <div class='openpopupgallery' data-imgindex='3' data-target='article-607968-popup'><span class="helper"></span><img src='https://pub.mdpi-res.com/ijerph/ijerph-18-08241/article_deploy/html/images/ijerph-18-08241-g004-550.jpg?1628067552'><p>Figure 4</p></div> --- <div class='openpopupgallery' data-imgindex='4' data-target='article-607968-popup'><span class="helper"></span><img src='https://pub.mdpi-res.com/ijerph/ijerph-18-08241/article_deploy/html/images/ijerph-18-08241-g005-550.jpg?1628067552'><p>Figure 5</p></div></script></div></div><div id="article-607968-popup" class="popupgallery" style="display: inline; line-height: 200%"><a href="https://pub.mdpi-res.com/ijerph/ijerph-18-08241/article_deploy/html/images/ijerph-18-08241-g001-550.jpg?1628067552" title=" <strong>Figure 1</strong><br/> <p>(<b>A</b>) The virtual model of the defect obtained with the intraoral scanner (Trios 4, 3Shape, Copenhagen, Denmark).

A questionnaire including RPD framework design concepts, materials, and digital technology was created on Qualtrics. The link to the questionnaire was distributed by email in May 2018 to U.S. dental schools. Thirty-nine of the sixty-six schools responded, yielding a response rate of 59%. Most schools are utilizing textbooks by McCracken and/or Stewart as their primary reference (90%). Only a few schools teach incisal rest (24%) and intra-coronal retainers (8%) in the clinic. The majority of schools teach three or less clasp assembly variations for distal extension RPD scenarios and utilize altered cast impression techniques only for selective patient scenarios. Half of schools currently utilize digital technology in their RPD curriculum. Although twenty-five schools (69%) indicated that implant-assisted RPD (IARPD) is being taught in the curriculum, only nineteen of them teach IARPDs in the clinic. Half of schools are utilizing non-metal clasp denture (NMCD) in their curriculum; most of these school provide this treatment as immediate/interim partials or long-term interim partials. Many U.S. dental schools are simplifying RPD design concepts and principles that are being taught. More schools are introducing new concepts and materials such as IARPD and NMCDs while incorporating digital technology in their predoctoral RPD curriculum. <a href="/2673-1592/3/2/13">Full article</a> </div> </div> <div class="belongsTo" style="margin-bottom: 10px;"> (This article belongs to the Section <a href="/journal/prosthesis/sections/Prosthodontics">Prosthodontics</a>)<br/> </div> </div> </div> <div class="generic-item article-item"> <input class="article-list-checkbox export-element" type="checkbox" name="articles_ids[]" value="194550" data-select-all-name="article-listing"> <div class="article-content"> <div class="label right label__btn"> <span style="font-size: 12px; color: #1a1a1a;"> 6 pages, 2186 KiB   </span> <a href="/2304-6767/7/1/4/pdf?version=1546483311" class="UD_Listings_ArticlePDF" title="Article PDF" data-name="Use of a Polyetheretherketone Clasp Retainer for Removable Partial Denture: A Case Report" data-journal="dentistry"> <i class="material-icons custom-download"></i> </a> </div> <div class="article-icons"><span class="label openaccess" data-dropdown="drop-article-label-openaccess" aria-expanded="false">Open Access</span><span class="label articletype">Case Report</span></div> <a class="title-link" href="/2304-6767/7/1/4">Use of a Polyetheretherketone Clasp Retainer for Removable Partial Denture: A Case Report</a> <div class="authors"> by <span class="inlineblock "><strong>Tetsuo Ichikawa</strong>, </span><span class="inlineblock "><strong>Kosuke Kurahashi</strong>, </span><span class="inlineblock "><strong>Lipei Liu</strong>, </span><span class="inlineblock "><strong>Takashi Matsuda</strong> and </span><span class="inlineblock "><strong>Yuichi Ishida</strong></span> </div> <div class="color-grey-dark"> <em>Dent.

Two years later, few color and texture changes of PEEK were found macroscopically. The rest part and the clasp arm fitted well without any deformation. There were no particular occlusal or periodontal problems.
