However, cases of early failure, such as chipping or fracture in the veneering have been reported after short periods of use. The present study evaluated the feldspathic porcelain (VITA-VM9) with addition of 0.5 and 2.5 wt% Alumina-Zirconia as reinforcing agents. Hardness, fracture toughness, contact resistance and color variations were evaluated finding better mechanical performance on the new formulations. 2020 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43062873007 https://www.redalyc.org/journal/430/43062873007/ https://www.redalyc.org/journal/430/43062873007/html/ https://www.redalyc.org/journal/430/43062873007/43062873007.epub https://www.redalyc.org/journal/430/43062873007/movil 10.17533/udea.redin.n91a11 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.94 |
