Rigid implant splinting generated higher von Mises stress in the cortical bone under oblique loading.</AbstractText><AbstractText Label="CONCLUSION" NlmCategory="CONCLUSIONS">It was concluded that the use of a semirigid system for rehabilitation of edentulous mandibles by means of immediate implant-supported fixed complete denture is recommended, because it reduces stress concentration in the cortical bone. As a consequence, bone level is better preserved, and implant survival is improved. Nevertheless, for both situations the cortical bone integrity was protected, because the maximum stress level findings were lower than those pointed in the literature as being harmful. The maximum stress limit for cortical bone (167 MPa) represents the threshold between plastic and elastic state for a given material. Because any force is applied to an object, and there is no deformation, we can conclude that the elastic threshold was not surpassed, keeping its structural integrity. If the force is higher than the plastic threshold, the object will suffer permanent deformation. In cortical bone, this represents the beginning of bone resorption and/or remodeling processes, which, according to our simulated loading, would not occur.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Teixeira</LastName><ForeName>Marcelo Fontes</ForeName><Initials>MF</Initials><AffiliationInfo><Affiliation>Department of Oral Implantology, Faculty of Dentistry, Veiga de Almeida University, Rio de Janeiro, Brazil. mfonttes@uol.com.br</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Ramalho</LastName><ForeName>Saturnino Aparecido</ForeName><Initials>SA</Initials></Author><Author ValidYN="Y"><LastName>de Mattias Sartori</LastName><ForeName>Ivete Aparecida</ForeName><Initials>IA</Initials></Author><Author ValidYN="Y"><LastName>Lehmann</LastName><ForeName>Roberto Brunow</ForeName><Initials>RB</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType></PublicationTypeList></Article><MedlineJournalInfo><Country>United States</Country><MedlineTA>Implant Dent</MedlineTA><NlmUniqueID>9206481</NlmUniqueID><ISSNLinking>1056-6163</ISSNLinking></MedlineJournalInfo><CitationSubset>D</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName UI="D003198" MajorTopicYN="N">Computer Simulation</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D003758" MajorTopicYN="N">Dental Implantation, Endosseous</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D019094" MajorTopicYN="Y">Dental Prosthesis, Implant-Supported</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D003799" MajorTopicYN="N">Dental Stress Analysis</DescriptorName><QualifierName UI="Q000379" MajorTopicYN="Y">methods</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D003825" MajorTopicYN="N">Denture, Complete, Immediate</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D004548" MajorTopicYN="N">Elasticity</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D020342" MajorTopicYN="N">Finite Element Analysis</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D006801" MajorTopicYN="N">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D007575" MajorTopicYN="N">Jaw, Edentulous</DescriptorName><QualifierName UI="Q000503" MajorTopicYN="Y">physiopathology</QualifierName><QualifierName UI="Q000534" MajorTopicYN="N">rehabilitation</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D008334" MajorTopicYN="N">Mandible</DescriptorName><QualifierName UI="Q000502" MajorTopicYN="N">physiology</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D008954" MajorTopicYN="Y">Models, Biological</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D010516" MajorTopicYN="Y">Periodontal Splints</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D013314" MajorTopicYN="N">Stress, Mechanical</DescriptorName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="entrez"><Year>2010</Year><Month>2</Month><Day>12</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2010</Year><Month>2</Month><Day>12</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2010</Year><Month>5</Month><Day>11</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">20147815</ArticleId><ArticleId IdType="doi">10.1097/ID.0b013e3181cc7ffc</ArticleId><ArticleId IdType="pii">00008505-201002000-00007</ArticleId></ArticleIdList></PubmedData></pubmed><affiliations><list><country><li>Brésil</li></country><region><li>État de Rio de Janeiro</li></region><settlement><li>Rio de Janeiro</li></settlement></list><tree><noCountry><name sortKey="De Mattias Sartori, Ivete Aparecida" sort="De Mattias Sartori, Ivete Aparecida" uniqKey="De Mattias Sartori I" first="Ivete Aparecida" last="De Mattias Sartori">Ivete Aparecida De Mattias Sartori</name><name sortKey="Lehmann, Roberto Brunow" sort="Lehmann, Roberto Brunow" uniqKey="Lehmann R" first="Roberto Brunow" last="Lehmann">Roberto Brunow Lehmann</name><name sortKey="Ramalho, Saturnino Aparecido" sort="Ramalho, Saturnino Aparecido" uniqKey="Ramalho S" first="Saturnino Aparecido" last="Ramalho">Saturnino Aparecido Ramalho</name></noCountry><country name="Brésil"><region name="État de Rio de Janeiro"><name sortKey="Teixeira, Marcelo Fontes" sort="Teixeira, Marcelo Fontes" uniqKey="Teixeira M" first="Marcelo Fontes" last="Teixeira">Marcelo Fontes Teixeira</name></region></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
