Mean values were analyzed by 2-way ANOVA and Tukey's test (α=0.05). The wear of Trubyte Biotone (0.93 ± 0.14 mm) was significantly higher than that of both other types of teeth tested against abraded ceramic (p<0.05). The Vivodent tooth (0.64 ± 0.17 mm) exhibited the best wear resistance among the denture teeth tested against airborne particle abraded ceramic. There were no statistically significant differences (p>0.05) in wear among the 3 denture teeth evaluated against glazed ceramic. Trilux and Vivodent teeth tested against either glazed or airborne particle abraded ceramic did not differ significantly from each other (p<0.05). All teeth showed significantly more wear against airborne particle abraded ceramic than against glazed ceramic (p<0.05). In conclusion, the three types of PMMA denture teeth presented significantly different wear resistance against the abraded ceramic. The high-strength PMMA denture teeth were more wear-resistant than the conventional PMMA denture tooth.</p></div></front><back><div1 type="bibliography"><listBibl><biblStruct><analytic><author><name

Trilux and Vivodent teeth tested against either glazed or airborne particle abraded ceramic did not differ significantly from each other (p<0.05). All teeth showed significantly more wear against airborne particle abraded ceramic than against glazed ceramic (p<0.05). In conclusion, the three types of PMMA denture teeth presented significantly different wear resistance against the abraded ceramic. The high-strength PMMA denture teeth were more wear-resistant than the conventional PMMA denture tooth.</p></abstract><kwd-group><kwd>Denture teeth</kwd><kwd>Polymethyl methacrylate</kwd><kwd>Acrylic resin</kwd><kwd>Wear resistance</kwd></kwd-group><counts><fig-count count="1"></fig-count><table-count count="2"></table-count><equation-count count="0"></equation-count><ref-count count="31"></ref-count><page-count count="5"></page-count></counts></article-meta></front></pmc></record>Pour manipuler ce document sous Unix (Dilib)
