Resistencia de cerámicas de disilicato de litio adheridas con dos adhesivos diferentes

Abstract

Antecedentes: La cerámica de disilicato de litio es una excelente opción en rehabilitación, confeccionado con la técnica de inyección o maquinadas. Objetivo: Evaluar la influencia de los sistemas adhesivos universales sin silano sobre los valores de resistencia de unión en cerámicas de disilicato de litio inyectado y maquinado. Métodos: Se utilizó discos de disilicato de litio, IPS e. Max CAD (Ivoclar Vivadent, Liechtenstein, Swiss), de 10mm de diámetro y 1mm de espesor embebidos en tubos de PVC, se distribuyó en 4 grupos de trabajo, 2 en cerámica de litio inyectadas y 2 en maquinada, se aplicaron los adhesivos Palfique Bond y Tetric N-bond Universal según la distribución de grupos, luego se fotopolimerizó durante 10 segundos con lámpara luz led, se colocaron los tubos tygon para el relleno con resina fluida, una vez retirado los tubos tygon, se llevaron las muestras a una máquina de ensayo universal donde se realizó la prueba de microcizallamiento. Resultados: Los valores de resistencia de unión más significativos fueron encontrados en las cerámicas de disilicato de litio adherida con el adhesivo Palfique Bond y Tetric Bond teniendo una diferencia significativa (p= 0.001), Los valores de resistencia de unión del adhesivo Palfique Bond y Tetric Bond en cerámica inyectada no tuvieron diferencia significativa. Conclusión: Las cerámicas de disilicato de litio maquinadas presentan mayores valores de resistencia de unión al microcizallamiento.

Background: Lithium disilicate ceramics are an excellent choice in rehabilitation, made with the technique of injection or machining Objective: Evaluate the influence of universal adhesive systems without silane on bonding strength values in injected and machined lithium disilicate ceramics. Materials and methods: Lithium disilicate disks, IPS e.. Were used Max CAD (Ivoclar Vivadent, Liechtenstein, Swiss), 10mm in diameter and 1mm in thickness embedded in PVC tubes, was distributed in 4 working groups, 2 in injected lithium ceramics and 2 in machined, Palfique Bond and Tetric N-bond Universal adhesives were applied according to the group distribution, then photopolymerized for 10 seconds with led light bulb, tygon tubes were placed for filling with fluid resin, once the tygon tubes were removed. The samples were taken to a universal test machine where the micro-spraying test was performed. Results: The most significant binding resistance values were found in lithium disisilicate ceramics adhered with the Palfique Bond and Tetric Bond adhesive having a significant difference (p= 0.001), the bond strength values of the Palfique Bond and Tetric Bond adhesive in injected ceramic did not differ significantly. Conclusion: Machined lithium disilicate ceramics have better values of binding resistance to micro spraying.
