Three pressure transducers were embedded in the oral analog-one pressure transducer in the anterior ridge area, and the other two in the right and left buccal shelves. Four configurations of custom trays were fabricated: trays with no relief, with and without holes; and trays with relief, with and without holes. The impression materials tested were light body polysulfide, light body vinyl polysiloxane, medium body vinyl polysiloxane, and irreversible hydrocolloid. The custom tray and the oral analog were mounted using a reline jig, and a Satec universal testing machine was used to apply a constant pressure of 1 kg/cm(2) over a period of 5 minutes on the loaded custom tray. Eighty impressions for the 16 groups (n = 5) were made, and pressures were recorded every 10 seconds. Factorial ANOVA and Tukey Multiple Comparison Test were used to analyze the results (p < 0.05).</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">A significant difference was found in the pressure produced using different impression materials. Irreversible hydrocolloid and medium body vinyl polysiloxane produced significantly higher pressure than light body polysulfide and light body vinyl polysiloxane impression materials. The presence of holes and/or relief significantly altered the magnitude of pressure produced by irreversible hydrocolloid and medium body vinyl polysiloxane but not light body polysulfide and light body vinyl polysiloxane.</AbstractText><AbstractText Label="CONCLUSION" NlmCategory="CONCLUSIONS">All impression materials produced pressure during simulated mandibular edentulous impression making. For making mandibular edentulous impressions, low-viscosity impression materials-light body polysulfide and light body vinyl polysiloxane-are recommended. Tray modification was not important in changing the amount of pressure produced for the low-viscosity impression materials.</AbstractText><CopyrightInformation>Copyright 2006 by The American College of Prosthodontists.</CopyrightInformation></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Al-Ahmad</LastName><ForeName>Adel</ForeName><Initials>A</Initials><AffiliationInfo><Affiliation>Department of Endodontics, Prosthodontics, and Operative Dentistry, Baltimore College of Dental Surgery, University of Maryland, MD 21201, USA.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Masri</LastName><ForeName>Radi</ForeName><Initials>R</Initials></Author><Author ValidYN="Y"><LastName>Driscoll</LastName><ForeName>Carl F</ForeName><Initials>CF</Initials></Author><Author ValidYN="Y"><LastName>von Fraunhofer</LastName><ForeName>Joseph</ForeName><Initials>J</Initials></Author><Author ValidYN="Y"><LastName>Romberg</LastName><ForeName>Elaine</ForeName><Initials>E</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType></PublicationTypeList></Article><MedlineJournalInfo><Country>United States</Country><MedlineTA>J Prosthodont</MedlineTA><NlmUniqueID>9301275</NlmUniqueID><ISSNLinking>1059-941X</ISSNLinking></MedlineJournalInfo><ChemicalList><Chemical><RegistryNumber>0</RegistryNumber><NameOfSubstance UI="D003760">Dental Impression Materials</NameOfSubstance></Chemical></ChemicalList><CitationSubset>D</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName UI="D000704" MajorTopicYN="N">Analysis of Variance</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D003760" MajorTopicYN="N">Dental Impression Materials</DescriptorName><QualifierName UI="Q000737" MajorTopicYN="Y">chemistry</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D003761" MajorTopicYN="N">Dental Impression Technique</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D003765" MajorTopicYN="Y">Dental Models</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D006801" MajorTopicYN="N">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D007575" MajorTopicYN="Y">Jaw, Edentulous</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D011312" MajorTopicYN="N">Pressure</DescriptorName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="pubmed"><Year>2006</Year><Month>5</Month><Day>3</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2006</Year><Month>6</Month><Day>20</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2006</Year><Month>5</Month><Day>3</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">16650009</ArticleId><ArticleId IdType="pii">JOPR081</ArticleId><ArticleId IdType="doi">10.1111/j.1532-849X.2006.00081.x</ArticleId></ArticleIdList></PubmedData></pubmed><affiliations><list><country><li>États-Unis</li></country><region><li>Maryland</li></region><settlement><li>College Park (Maryland)</li></settlement><orgName><li>Université du Maryland</li></orgName></list><tree><noCountry><name sortKey="Driscoll, Carl F" sort="Driscoll, Carl F" uniqKey="Driscoll C" first="Carl F" last="Driscoll">Carl F.
