Abstract
Increasing life expectancy, age related reduction in adaptability and progressive severe mandibular resorption all add to the importance of any factor improving the prosthetic success. Objective: To investigate the effect of two different lingual shapes of lower dentures on patients' ability to resist lifting forces. Design: Tongue pressures on the lingual surface of complete mandibular experimental dentures were recorded from mid‐line, premolar and molar transducers. Two experimental prostheses were fabricated for each subject: one conventionally contoured, the other formed by piezography. Setting: A clinical research laboratory. Subjects Five experienced complete denture wearers between age 64 and 82 years. Intervention Lifting forces were applied at the midline, left and right premolar sites in random order. Main outcome measures: Peak resistance to lifting forces and lingual pressures used during these tests. Results: Lingual pressures exerted anteriorly were dramatically higher than those on premolar and molar surfaces. Significantly higher pressures were used to resist lifting forces applied to piezographically than conventionally formed contours; correspondingly, significantly higher lifting peak forces were, on average, resisted. Conclusions: Providing a lower denture with a piezographically produced lingual surface was shown, in this preliminary study, to enhance tongue retentive ability over a conventional design. It seems reasonable to maximise retentive potential with oblique sublingual polished surfaces and minimise the adaptive demand, particularly for older patients, by using a piezographic technique which “customises” the contour and precludes over‐extension.

Objective: To investigate the effect of two different lingual shapes of lower dentures on patients' ability to resist lifting forces. Design: Tongue pressures on the lingual surface of complete mandibular experimental dentures were recorded from mid‐line, premolar and molar transducers. Two experimental prostheses were fabricated for each subject: one conventionally contoured, the other formed by piezography. Setting: A clinical research laboratory. Subjects Five experienced complete denture wearers between age 64 and 82 years. Intervention Lifting forces were applied at the midline, left and right premolar sites in random order. Main outcome measures: Peak resistance to lifting forces and lingual pressures used during these tests. Results: Lingual pressures exerted anteriorly were dramatically higher than those on premolar and molar surfaces. Significantly higher pressures were used to resist lifting forces applied to piezographically than conventionally formed contours; correspondingly, significantly higher lifting peak forces were, on average, resisted. Conclusions: Providing a lower denture with a piezographically produced lingual surface was shown, in this preliminary study, to enhance tongue retentive ability over a conventional design. It seems reasonable to maximise retentive potential with oblique sublingual polished surfaces and minimise the adaptive demand, particularly for older patients, by using a piezographic technique which “customises” the contour and precludes over‐extension.</abstract><subject lang="en"><genre>keywords</genre><topic>Lower dentures</topic><topic>retention</topic><topic>tongue</topic><topic>gerodontics</topic></subject><relatedItem type="host"><titleInfo><title>Gerodontology</title></titleInfo><genre type="journal" authority="ISTEX" authorityURI="https://publication-type.data.istex.fr" valueURI="https://publication-type.data.istex.fr/ark:/67375/JMC-0GLKJH51-B">journal</genre><identifier type="ISSN">0734-0664</identifier><identifier type="eISSN">1741-2358</identifier><identifier type="DOI">10.1111/(ISSN)1741-2358</identifier><identifier type="PublisherID">GER</identifier><part><date>1998</date><detail type="volume"><caption>vol.</caption><number>15</number></detail><detail type="issue"><caption>no.</caption><number>2</number></detail><extent unit="pages"><start>113</start><end>119</end><total>7</total></extent></part></relatedItem><identifier type="istex">AD91149C96F80CA085A30FBED862CD46EF368EE0</identifier><identifier type="ark">ark:/67375/WNG-RNPGM6X1-Z</identifier><identifier type="DOI">10.1111/j.1741-2358.1998.00113.x</identifier><identifier type="ArticleID">GER113</identifier><recordInfo><recordContentSource authority="ISTEX" authorityURI="https://loaded-corpus.data.istex.fr" valueURI="https://loaded-corpus.data.istex.fr/ark:/67375/XBH-L0C46X92-X">wiley</recordContentSource><recordOrigin>Blackwell Publishing Ltd</recordOrigin></recordInfo></mods><json:item><extension>json</extension><original>false</original><mimetype>application/json</mimetype><uri>https://api.istex.fr/document/AD91149C96F80CA085A30FBED862CD46EF368EE0/metadata/json</uri></json:item></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
