Abstract
When implants are placed interforaminally in mandibular implant-supported screw-retained prostheses, the most anterior implant is usually positioned lingual to the incisors of the prosthesis. This creates an anterior cantilever with the entire prosthesis acting as a class I lever and possibly placing the anterior implant under alternating tension and compression during function.

This creates an anterior cantilever with the entire prosthesis acting as a class I lever and possibly placing the anterior implant under alternating tension and compression during function.</AbstractText><AbstractText Label="PURPOSE" NlmCategory="OBJECTIVE">The purpose of this study was to measure the anterior cantilever of randomly chosen patients with restored mandibular implant-supported fixed prostheses, and to establish the proportions of anterior to posterior cantilever lengths relative to the anteroposterior spread.</AbstractText><AbstractText Label="MATERIAL AND METHODS" NlmCategory="METHODS">Thirteen edentulous patients were recruited from the University of Minnesota's dental implant program. Each patient had been restored with a maxillary complete denture and a mandibular implant-supported screw-retained prosthesis supported by 5 endosseous implants. Each patient had 1 mandibular impression made with irreversible hydrocolloid, which was poured in type III gypsum. A FaroArm precision 3D measuring stylus was used to make multiple-axis (X-Y-Z) measurements (mm) on the casts of the dental implants, of anteroposterior spread, and anterior and posterior cantilevers. Presence or absence of screw loosening was noted using a screwdriver with finger pressure. Data were analyzed using a 1-way analysis of variance to compare prostheses with loose screws to prostheses without loose screws, for each of 3 outcome measures: length of anterior cantilever, length of posterior cantilever, and anteroposterior spread (P<.05).</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">Mandibular anterior cantilever lengths ranged from 5.5 to 14.4 mm with a mean of 8.78 mm. Combined posterior cantilever lengths ranged from 9.2 to 20.9 mm with a mean of 16.2 mm. Anteroposterior spread ranged from 5.2 to 12.3 mm with a mean of 7.9 mm. From a total of 65 retaining screws, 7 were found to be completely loose. No apparent correlation was found between length of mandibular anterior cantilever and screw loosening (P=.45), although the ratio of posterior cantilever to anteroposterior spread (2:4) was significantly associated with screw loosening (P=.006).</AbstractText><AbstractText Label="CONCLUSION" NlmCategory="CONCLUSIONS">Within the limitations of this study, anterior cantilevers in mandibular implant-supported screw-retained prostheses were frequent and appeared to depend on implant placement and prosthesis design. The ratio of anterior to posterior cantilever lengths was approximately 1:2.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Brosky</LastName><ForeName>M E</ForeName><Initials>ME</Initials><AffiliationInfo><Affiliation>School of Dentistry, Division of Prosthodontics, Department of Restorative Sciences, University of Minnesota, Minneapolis 55455, USA. brosk001@tc.umn.edu</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Korioth</LastName><ForeName>T W P</ForeName><Initials>TW</Initials></Author><Author ValidYN="Y"><LastName>Hodges</LastName><ForeName>J</ForeName><Initials>J</Initials></Author></AuthorList><Language>eng</Language><GrantList CompleteYN="Y"><Grant><GrantID>R01DE12225</GrantID><Acronym>DE</Acronym><Agency>NIDCR NIH HHS</Agency><Country>United States</Country></Grant></GrantList><PublicationTypeList><PublicationType UI="D003160">Comparative Study</PublicationType><PublicationType UI="D016428">Journal Article</PublicationType><PublicationType UI="D013485">Research Support, Non-U.S. Gov't</PublicationType><PublicationType UI="D013487">Research Support, U.S. Gov't, P.H.S.</PublicationType></PublicationTypeList></Article><MedlineJournalInfo><Country>United States</Country><MedlineTA>J Prosthet Dent</MedlineTA><NlmUniqueID>0376364</NlmUniqueID><ISSNLinking>0022-3913</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="D000368" MajorTopicYN="N">Aged</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D000369" MajorTopicYN="N">Aged, 80 and over</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D000704" MajorTopicYN="N">Analysis of Variance</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D015921" MajorTopicYN="Y">Dental Implants</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D003765" MajorTopicYN="N">Dental Models</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D019094" MajorTopicYN="Y">Dental Prosthesis, Implant-Supported</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D019232" MajorTopicYN="N">Dental Restoration Failure</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D003779" MajorTopicYN="Y">Denture Design</DescriptorName><QualifierName UI="Q000295" MajorTopicYN="N">instrumentation</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D005260" MajorTopicYN="N">Female</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D006801" MajorTopicYN="N">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D007575" MajorTopicYN="N">Jaw, Edentulous</DescriptorName><QualifierName UI="Q000534" MajorTopicYN="N">rehabilitation</QualifierName><QualifierName UI="Q000601" MajorTopicYN="N">surgery</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D008297" MajorTopicYN="N">Male</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D008334" MajorTopicYN="N">Mandible</DescriptorName><QualifierName UI="Q000601" MajorTopicYN="N">surgery</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D008875" MajorTopicYN="N">Middle Aged</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D011312" MajorTopicYN="N">Pressure</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D012399" MajorTopicYN="N">Rotation</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D013314" MajorTopicYN="N">Stress, Mechanical</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D016896" MajorTopicYN="N">Treatment Outcome</DescriptorName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="pubmed"><Year>2003</Year><Month>3</Month><Day>20</Day><Hour>4</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2003</Year><Month>7</Month><Day>2</Day><Hour>5</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2003</Year><Month>3</Month><Day>20</Day><Hour>4</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">12644798</ArticleId><ArticleId IdType="doi">10.1067/mpr.2003.43</ArticleId><ArticleId IdType="pii">S0022391302527438</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
