Abstract
Oral implants placed in the maxilla, especially the posterior region, have a lower success rate than those placed in the mandible. Poor bone quantity and quality have been suggested as a reason for this differential success rate.

It was found that stresses were more homogeneously distributed when more spongy bone was present. Decreased bone height was found to have less pronounced effects on strain and stress alterations than poor bone quality. Atrophic bony dimensions in combination with poor bone quality were associated with surface strains exceeding physiological levels (> 6,000 microstrains).</AbstractText><AbstractText Label="CONCLUSION" NlmCategory="CONCLUSIONS">Our investigation indicates that supraphysiological bone strains adjacent to the implant surface should be expected under mechanical loading in the atrophic maxilla.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Meyer</LastName><ForeName>U</ForeName><Initials>U</Initials><AffiliationInfo><Affiliation>Department of Cranio-Maxillofacial Surgery, University of Münster, Germany. ulmeyer@uni-muenster.de</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Vollmer</LastName><ForeName>D</ForeName><Initials>D</Initials></Author><Author ValidYN="Y"><LastName>Runte</LastName><ForeName>C</ForeName><Initials>C</Initials></Author><Author ValidYN="Y"><LastName>Bourauel</LastName><ForeName>C</ForeName><Initials>C</Initials></Author><Author ValidYN="Y"><LastName>Joos</LastName><ForeName>U</ForeName><Initials>U</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType></PublicationTypeList></Article><MedlineJournalInfo><Country>Scotland</Country><MedlineTA>J Craniomaxillofac Surg</MedlineTA><NlmUniqueID>8704309</NlmUniqueID><ISSNLinking>1010-5182</ISSNLinking></MedlineJournalInfo><ChemicalList><Chemical><RegistryNumber>0</RegistryNumber><NameOfSubstance UI="D015921">Dental Implants</NameOfSubstance></Chemical></ChemicalList><CitationSubset>D</CitationSubset><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName UI="D000539" MajorTopicYN="N">Alveolar Process</DescriptorName><QualifierName UI="Q000473" MajorTopicYN="N">pathology</QualifierName><QualifierName UI="Q000503" MajorTopicYN="N">physiopathology</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D001284" MajorTopicYN="N">Atrophy</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D015519" MajorTopicYN="N">Bone Density</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D003198" MajorTopicYN="N">Computer Simulation</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D015921" MajorTopicYN="Y">Dental Implants</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D017267" MajorTopicYN="N">Dental Prosthesis Design</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D020342" MajorTopicYN="Y">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="Q000473" MajorTopicYN="N">pathology</QualifierName><QualifierName UI="Q000503" MajorTopicYN="Y">physiopathology</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D008437" MajorTopicYN="N">Maxilla</DescriptorName><QualifierName UI="Q000473" MajorTopicYN="N">pathology</QualifierName><QualifierName UI="Q000503" MajorTopicYN="Y">physiopathology</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D008954" MajorTopicYN="Y">Models, Biological</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D016348" MajorTopicYN="N">Osseointegration</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D013314" MajorTopicYN="N">Stress, Mechanical</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D013499" MajorTopicYN="N">Surface Properties</DescriptorName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="pubmed"><Year>2001</Year><Month>7</Month><Day>24</Day><Hour>10</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2001</Year><Month>10</Month><Day>26</Day><Hour>10</Hour><Minute>1</Minute></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2001</Year><Month>7</Month><Day>24</Day><Hour>10</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">11465432</ArticleId><ArticleId IdType="pii">S1010-5182(01)90198-2</ArticleId><ArticleId IdType="doi">10.1054/jcms.2001.0198</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
