One examiner measured the bone height and width at selected sites in the images at three different times. Results were compared with a paired test in SAS 8.02.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">In relation to bone height, when the jaws were inclined to the inferior direction (gantry angle +19 degrees ), there was no statistically significant difference for any region studied. There was a statistically significant difference for the incisor region when the jaws were inclined to the superior direction (gantry angle -19 degrees ). With respect to the width of the bone rim, there was a statistically significant difference only for the region of the molars when the jaw was inclined to the inferior direction and for the region of the canine, when the inclination was to the superior direction.</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">Errors in mandibular positioning of 19 degrees produced image discrepancies with regard to bone height and width which were not excessive. Thus, examinations do not have to be repeated owing to variation of mandibular positioning because the differences were lower than 10% of the value found for the standard position.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Dantas</LastName><ForeName>J A</ForeName><Initials>JA</Initials><AffiliationInfo><Affiliation>Department of Dental Radiology, Piracicaba Dentistry School, University of Campinas, Brazil. janadantas@yahoo.com.br</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Montebello Filho</LastName><ForeName>A</ForeName><Initials>A</Initials></Author><Author ValidYN="Y"><LastName>Campos</LastName><ForeName>P S F</ForeName><Initials>PS</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType></PublicationTypeList></Article><MedlineJournalInfo><Country>England</Country><MedlineTA>Dentomaxillofac Radiol</MedlineTA><NlmUniqueID>7609576</NlmUniqueID><ISSNLinking>0250-832X</ISSNLinking></MedlineJournalInfo><ChemicalList><Chemical><RegistryNumber>0</RegistryNumber><NameOfSubstance UI="D015921">Dental Implants</NameOfSubstance></Chemical></ChemicalList><CitationSubset>D</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName UI="D003758" MajorTopicYN="N">Dental Implantation, Endosseous</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D015921" MajorTopicYN="Y">Dental Implants</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D006801" MajorTopicYN="N">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D007575" MajorTopicYN="N">Jaw, Edentulous</DescriptorName><QualifierName UI="Q000000981" MajorTopicYN="Y">diagnostic imaging</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D008334" MajorTopicYN="N">Mandible</DescriptorName><QualifierName UI="Q000000981" MajorTopicYN="Y">diagnostic imaging</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D010347" MajorTopicYN="N">Patient Care Planning</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D011187" MajorTopicYN="N">Posture</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D011861" MajorTopicYN="N">Radiography, Dental</DescriptorName><QualifierName UI="Q000379" MajorTopicYN="Y">methods</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D014057" MajorTopicYN="N">Tomography, X-Ray Computed</DescriptorName><QualifierName UI="Q000379" MajorTopicYN="N">methods</QualifierName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="pubmed"><Year>2005</Year><Month>2</Month><Day>15</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2005</Year><Month>4</Month><Day>5</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2005</Year><Month>2</Month><Day>15</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">15709099</ArticleId><ArticleId IdType="pii">34/1/9</ArticleId><ArticleId IdType="doi">10.1259/dmfr/57866813</ArticleId></ArticleIdList></PubmedData></pubmed><affiliations><list><country><li>Brésil</li></country></list><tree><noCountry><name sortKey="Campos, P S F" sort="Campos, P S F" uniqKey="Campos P" first="P S F" last="Campos">P S F.
