Resumen
Objetivo: Analizar protocolos de tratamiento superficial que optimicen la resistencia de adhesión a cerámicas de circonio entre los diferentes tratamientos disponibles. Métodos: Revisión integradora de artículos publicados entre 2013 y 2023, en inglés y texto completo, utilizando Pubmed con los descriptores “zirconia”, “surface treatment”, “bond strength”, “resin cements” y “cementation” combinados con “AND”. Resultados: Se seleccionaron 17 artículos basados en criterios de inclusión y exclusión. Los tratamientos se clasificaron en mecánicos (abrasión con partículas, sistemas Rocatec, Siljet, Cojet y láseres) y químicos (infiltración selectiva, ácido fluorhídrico y primers/silanos con MDP). La abrasión por granallado mejoró la adhesión, aunque puede generar fragilidad. Sistemas como Rocatec, Siljet y Cojet ofrecieron buena retención micromecánica con sílice, mientras que los láseres no mostraron mejoras significativas. El acondicionamiento por infiltración selectiva resultó efectivo sin causar fracturas. Las soluciones de HF y los primers/silanos mostraron un rendimiento insatisfactorio. Consideraciones finales: No hay un protocolo universal, pero técnicas específicas pueden mejorar la resistencia de unión a largo plazo.
