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.spahttps://v2.sherpa.ac.uk/id/publication/issn/0120-6230Dental ceramicsreinforcing agentfractureHertzian contactinfo:eu-repo/semantics/article2021-04-12Gomez Tamayo, JulianaRueda Arango, Astrid OasisOssa Henao, Edgar Alexander10.17533/udea.redin.n91a11
