Dental wear produced by monolithic zirconia crowns on opposing natural teeth compared to metal-ceramic crowns.Abstract
Objetivo: Realizar una revisión sistematizada sobre la comparación del desgaste que ejercen las coronas de zirconia monolítica y de metal-porcelana sobre los dientes naturales antagonistas. Materiales y métodos: Se llevo a cabo una búsqueda sistemática de diferentes bases de datos (Pubmed, Scopus, Google Scholar y Scielo) y se seleccionaron 6 artículos sobre el tema de los cuales 4 fueron estudios in vivo y 2 in vitro. Resultados: En 2 estudios in vivo la corona de zirconia monolítica ejercía un menor desgaste a comparación de la metalo-cerámica en el control de 1 año. 1 estudio in vivo señala que la zirconia monolítica ejerce un menor desgaste al diente natural antagonista en un control de 6 meses, pero ejerce mayor desgaste que la metal cerámica al año. 1 estudio in vivo señala que la zirconia monolítica ejerce mayor desgaste que la metal cerámica en controles de 6 meses y 1 año. Los estudios in vitro señalan que la corona de zirconia monolítica ejerce menor desgaste al diente natural antagonista entre 240. 000 a 250 000 ciclos de masticación, que es equivalente a 1 año. Conclusiones: Tanto las coronas de zirconia monolítica como las de metal cerámica poseen un buen comportamiento dentro del sistema masticatorio, si bien los estudios demostrarían que la corona de zirconia monolítica ejercería un menor desgaste al diente antagonista, existen otros factores que influyen en el desgaste, como el acabado final de la corona: glaseada o pulida.Objective: To carry out a systematic review on the comparison of the wear exerted by monolithic zirconia crowns and metal-porcelain crowns on opposing natural teeth. Materials and methods: A systematic search of different databases (Pubmed, Scopus, Google Scholar and Scielo) was carried out and 6 articles on the subject were selected, of which 4 were in vivo studies and 2 were in vitro. Results: In 2 in vivo studies, the monolithic zirconia crown exerted less wear than the metallo-ceramic crown in the 1-year control. 1 in vivo study indicates that monolithic zirconia exerts less wear on the opposing natural tooth in a 6-month follow-up, but exerts greater wear than ceramic metal after one year. 1 in vivo study indicates that monolithic zirconia exerts greater wear than ceramic metal in 6-month and 1-year controls. In vitro studies indicate that the monolithic zirconia crown exerts less wear on the opposing natural tooth between 240,000 to 250,000 chewing cycles, which is equivalent to 1 year. Conclusions: Both monolithic zirconia crowns and metal-ceramic crowns behave well within the masticatory system, although studies would show that the monolithic zirconia crown would exert less wear on the opposing tooth, there are other factors that influence wear, such as final finish of the crown: glazed or polished.
