Abstract
One of the most important properties of artificial teeth is the abrasion wear resistance, which is determinant in the maintenance of the rehabilitation's occlusal pattern.
This
Seven groups were prepared with 12 specimens each (BIOLUX – BL, TRILUX – TR, BLUE DENT – BD, BIOCLER – BC, POSTARIS – PO, ORTHOSIT – OR, GNATHOSTAR – GN), opposed to metallic (M – nickel-chromium alloy), and to composite antagonists (C – Solidex indirect composite). A mechanical loading device was used (240 cycles/min, 4 Hz speed, 10 mm antagonist course). Initial and final contours of each specimen were registered with aid of a profile projector (20x magnification). The linear difference between the two profiles was measured and the registered values were subjected to ANOVA and Tukey's test.
Regarding the antagonists, only OR (M = 10.45 ± 1.42 μm and C = 2.77 ± 0.69 μm) and BC (M = 6.70 ± 1.37 μm and C = 4.48 ± 0.80 μm) presented statistically significant differences (p < 0.05). Best results were obtained with PO (C = 2.33 ± 0.91 μm and M = 1.78 ± 0.42 μm), followed by BL (C = 3.70 ± 1.32 μm and M = 3.70 ± 0.61 μm), statistically similar for both antagonists (p>0.05). Greater result variance was obtained with OR, which presented the worse results opposed to Ni-Cr (10.45 ± 1.42 μm), and results similar to the best ones against composite (2.77 ± 0.69 μm).
Within the limitations of this study, it may be concluded that the antagonist material is a factor of major importance to be considered in the choice of the artificial teeth to be used in the prosthesis.

A mechanical loading device was used (240 cycles/min, 4 Hz speed, 10 mm antagonist course). Initial and final contours of each specimen were registered with aid of a profile projector (20x magnification). The linear difference between the two profiles was measured and the registered values were subjected to ANOVA and Tukey's test.</p></sec><sec><title>Results:</title><p>Regarding the antagonists, only OR (M = 10.45 ± 1.42 μm and C = 2.77 ± 0.69 μm) and BC (M = 6.70 ± 1.37 μm and C = 4.48 ± 0.80 μm) presented statistically significant differences (p < 0.05). Best results were obtained with PO (C = 2.33 ± 0.91 μm and M = 1.78 ± 0.42 μm), followed by BL (C = 3.70 ± 1.32 μm and M = 3.70 ± 0.61 μm), statistically similar for both antagonists (p>0.05). Greater result variance was obtained with OR, which presented the worse results opposed to Ni-Cr (10.45 ± 1.42 μm), and results similar to the best ones against composite (2.77 ± 0.69 μm).</p></sec><sec><title>Conclusions:</title><p>Within the limitations of this study, it may be concluded that the antagonist material is a factor of major importance to be considered in the choice of the artificial teeth to be used in the prosthesis.</p></sec></abstract><kwd-group><kwd>Tooth, artificial</kwd><kwd>Comparative study</kwd><kwd>Tooth abrasion</kwd></kwd-group><counts><fig-count count="4"></fig-count><table-count count="0"></table-count><equation-count count="0"></equation-count><ref-count count="19"></ref-count><page-count count="6"></page-count></counts></article-meta></front></pmc><affiliations><list><country><li>Brésil</li></country><region><li>État de São Paulo</li></region><settlement><li>São Paulo</li></settlement><orgName><li>Université de São Paulo</li></orgName></list><tree><country name="Brésil"><region name="État de São Paulo"><name sortKey="Mello, Pamela Carbone" sort="Mello, Pamela Carbone" uniqKey="Mello P" first="Pâmela Carbone" last="Mello">Pâmela Carbone Mello</name></region><name sortKey="Coppede, Abilio Ricciardi" sort="Coppede, Abilio Ricciardi" uniqKey="Coppede A" first="Abílio Ricciardi" last="Coppedê">Abílio Ricciardi Coppedê</name><name sortKey="De Mattos, Maria Da Gloria Chiarello" sort="De Mattos, Maria Da Gloria Chiarello" uniqKey="De Mattos M" first="Maria Da Gloria Chiarello" last="De Mattos">Maria Da Gloria Chiarello De Mattos</name><name sortKey="Macedo, Ana Paula" sort="Macedo, Ana Paula" uniqKey="Macedo A" first="Ana Paula" last="Macedo">Ana Paula Macedo</name><name sortKey="Ribeiro, Ricardo Faria" sort="Ribeiro, Ricardo Faria" uniqKey="Ribeiro R" first="Ricardo Faria" last="Ribeiro">Ricardo Faria Ribeiro</name><name sortKey="Rodrigues, Renata Cristina Silveira" sort="Rodrigues, Renata Cristina Silveira" uniqKey="Rodrigues R" first="Renata Cristina Silveira" last="Rodrigues">Renata Cristina Silveira Rodrigues</name></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
