Abstract
The non-homogenous aspect of periodontal ligament (PDL) has been examined using finite element analysis (FEA) to better simulate PDL behavior. The aim of this study was to assess, by 2-D FEA, the influence of non-homogenous PDL on the stress distribution when the free-end saddle removable partial denture (RPD) is partially supported by an osseointegrated implant.
Six finite element (FE) models of a partially edentulous mandible were created to represent two types of PDL (non-homogenous and homogenous) and two types of RPD (conventional RPD, supported by tooth and fibromucosa; and modified RPD, supported by tooth and implant [10.00x3.75 mm]). Two additional FE models without RPD were used as control models. The non-homogenous PDL was modeled using beam elements to simulate the crest, horizontal, oblique and apical fibers. The load (50 N) was applied in each cusp simultaneously. Regarding boundary conditions the border of alveolar ridge was fixed along the x axis. The FE software (Ansys 10.0) was used to compute the stress fields, and the von Mises stress criterion (σvM) was applied to analyze the results.
The peak of σvM in non-homogenous PDL was higher than that for the homogenous condition. The benefits of implants were enhanced for the non-homogenous PDL condition, with drastic σvM reduction on the posterior half of the alveolar ridge. The implant did not reduce the stress on the support tooth for both PDL conditions.
The PDL modeled in the non-homogeneous form increased the benefits of the osseointegrated implant in comparison with the homogeneous condition. Using the non-homogenous PDL, the presence of osseointegrated implant did not reduce the stress on the supporting tooth.

alveolar ridge was fixed along the x axis. The FE software (Ansys 10.0) was used
to compute the stress fields, and the von Mises stress criterion (σvM) was
applied to analyze the results. </p></sec><sec><title>Results</title><p>The peak of σvM in non-homogenous PDL was higher than that for the
homogenous condition. The benefits of implants were enhanced for the
non-homogenous PDL condition, with drastic σvM reduction on the posterior
half of the alveolar ridge. The implant did not reduce the stress on the support
tooth for both PDL conditions. </p></sec><sec><title>Conclusion</title><p>The PDL modeled in the non-homogeneous form increased the benefits of the
osseointegrated implant in comparison with the homogeneous condition. Using the
non-homogenous PDL, the presence of osseointegrated implant did not reduce the
stress on the supporting tooth.</p></sec></abstract><kwd-group><kwd>Removable partial denture</kwd><kwd>Dental implant</kwd><kwd>Finite element analysis</kwd><kwd>Periodontal ligament</kwd></kwd-group></article-meta></front></pmc><affiliations><list><country><li>Brésil</li></country><region><li>Paraná (État)</li><li>État de São Paulo</li></region></list><tree><country name="Brésil"><region name="Paraná (État)"><name sortKey="Archangelo, Carlos Marcelo" sort="Archangelo, Carlos Marcelo" uniqKey="Archangelo C" first="Carlos Marcelo" last="Archangelo">Carlos Marcelo Archangelo</name></region><name sortKey="Anchieta, Rodolfo Bruniera" sort="Anchieta, Rodolfo Bruniera" uniqKey="Anchieta R" first="Rodolfo Bruniera" last="Anchieta">Rodolfo Bruniera Anchieta</name><name sortKey="Freitas Junior, Amilcar Chagas" sort="Freitas Junior, Amilcar Chagas" uniqKey="Freitas Junior A" first="Amilcar Chagas" last="Freitas Júnior">Amilcar Chagas Freitas Júnior</name><name sortKey="Martin Junior, Manoel" sort="Martin Junior, Manoel" uniqKey="Martin Junior M" first="Manoel" last="Martin Junior">Manoel Martin Junior</name><name sortKey="Pereira, Joao Antonio" sort="Pereira, Joao Antonio" uniqKey="Pereira J" first="João Antônio" last="Pereira">João Antônio Pereira</name><name sortKey="Rocha, Eduardo Passos" sort="Rocha, Eduardo Passos" uniqKey="Rocha E" first="Eduardo Passos" last="Rocha">Eduardo Passos Rocha</name></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
