Abstract
The precise fit of an implant prosthesis is considered to be a prerequisite for the success and maintenance of osseointegration. It is unknown how much static stress can be tolerated at the implant-bone interface with ill-fitting prostheses for the two different types of retention (cement vs screw).

It is unknown how much static stress can be tolerated at the implant-bone interface with ill-fitting prostheses for the two different types of retention (cement vs screw).</AbstractText><AbstractText Label="PURPOSE" NlmCategory="OBJECTIVE">The purpose of this study was to evaluate the stress pattern and magnitude in the supporting tissues around ITI (Straumann AG, Waldenburg, Switzerland) implants with screw- or cement-retained prostheses with marginal gaps by photoelastic analysis.</AbstractText><AbstractText Label="MATERIALS AND METHODS" NlmCategory="METHODS">A photoelastic model of a human mandible, partially edentulous distal to the canine, was made of PL-2 resin. Three ITI implants (4.1 × 10 mm, Straumann AG, Waldenburg, Switzerland) were placed in the posterior edentulous region, and screw- or cement-retained three-unit fixed partial dentures (FPDs) were fabricated. Ill-fitting prostheses were made by placing a 100-μm gap between the abutments and the superstructures on the second premolar or the first molar. A static vertical force of 134 N was applied at three loading points on each prosthesis. Photoelastic stress analysis was carried out to measure the fringe order around the implant-supporting structures.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">Even in the unloaded condition, low-level stresses were generated around the implants after screw tightening or cementing the three-unit FPDs with marginal gaps. Loading on the terminal implants developed high concentrated stresses around the loaded implant, regardless of the types of restorations or the presence of gaps. However, when the middle implant was loaded, moderate stresses were distributed to the anterior and posterior implants.</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">Screw-retained FPDs with gaps exhibited a wider range of stresses on the interproximal region of adjacent implants than cement-retained FPDs. However, severe misfit in the prosthesis caused the nonaxial stress transfer to the adjacent implants in the cement-retained FPDs with gaps.</AbstractText><CopyrightInformation>© 2013 Wiley Periodicals, Inc.</CopyrightInformation></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Lee</LastName><ForeName>Jae-In</ForeName><Initials>JI</Initials><AffiliationInfo><Affiliation>Department of Prosthodontics, College of Dentistry, Wonkwang University, Iksan, Korea.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Lee</LastName><ForeName>Yoon</ForeName><Initials>Y</Initials></Author><Author ValidYN="Y"><LastName>Kim</LastName><ForeName>Nan-Young</ForeName><Initials>NY</Initials></Author><Author ValidYN="Y"><LastName>Kim</LastName><ForeName>Yu-Lee</ForeName><Initials>YL</Initials></Author><Author ValidYN="Y"><LastName>Cho</LastName><ForeName>Hye-Won</ForeName><Initials>HW</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType><PublicationType UI="D013485">Research Support, Non-U.S. Gov't</PublicationType></PublicationTypeList><ArticleDate DateType="Electronic"><Year>2013</Year><Month>08</Month><Day>09</Day></ArticleDate></Article><MedlineJournalInfo><Country>United States</Country><MedlineTA>Clin Implant Dent Relat Res</MedlineTA><NlmUniqueID>100888977</NlmUniqueID><ISSNLinking>1523-0899</ISSNLinking></MedlineJournalInfo><ChemicalList><Chemical><RegistryNumber>0</RegistryNumber><NameOfSubstance UI="D003738">Dental Cements</NameOfSubstance></Chemical><Chemical><RegistryNumber>0</RegistryNumber><NameOfSubstance UI="D015921">Dental Implants</NameOfSubstance></Chemical></ChemicalList><CitationSubset>D</CitationSubset><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName UI="D001863" MajorTopicYN="Y">Bone Screws</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D003738" MajorTopicYN="Y">Dental Cements</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D015921" MajorTopicYN="Y">Dental Implants</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D006801" MajorTopicYN="N">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D013314" MajorTopicYN="Y">Stress, Mechanical</DescriptorName></MeshHeading></MeshHeadingList><KeywordList Owner="NOTNLM"><Keyword MajorTopicYN="N">cement-retained FPD</Keyword><Keyword MajorTopicYN="N">dental implant</Keyword><Keyword MajorTopicYN="N">gap prosthesis</Keyword><Keyword MajorTopicYN="N">photoelasticity</Keyword><Keyword MajorTopicYN="N">screw-retained FPD</Keyword></KeywordList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="entrez"><Year>2013</Year><Month>8</Month><Day>10</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2013</Year><Month>8</Month><Day>10</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2015</Year><Month>9</Month><Day>12</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">23927066</ArticleId><ArticleId IdType="doi">10.1111/cid.12134</ArticleId></ArticleIdList></PubmedData></pubmed><affiliations><list><country><li>Corée du Sud</li></country></list><tree><noCountry><name sortKey="Cho, Hye Won" sort="Cho, Hye Won" uniqKey="Cho H" first="Hye-Won" last="Cho">Hye-Won Cho</name><name sortKey="Kim, Nan Young" sort="Kim, Nan Young" uniqKey="Kim N" first="Nan-Young" last="Kim">Nan-Young Kim</name><name sortKey="Kim, Yu Lee" sort="Kim, Yu Lee" uniqKey="Kim Y" first="Yu-Lee" last="Kim">Yu-Lee Kim</name><name sortKey="Lee, Yoon" sort="Lee, Yoon" uniqKey="Lee Y" first="Yoon" last="Lee">Yoon Lee</name></noCountry><country name="Corée du Sud"><noRegion><name sortKey="Lee, Jae In" sort="Lee, Jae In" uniqKey="Lee J" first="Jae-In" last="Lee">Jae-In Lee</name></noRegion></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
