Resumen
Objetivo: Evaluar la influencia de la limpieza con diferentes pastillas de limpieza en la rugosidad superficial de placas oclusales de PMMA mediante impresión CAD/CAM aditiva, discutiendo las posibles implicaciones para la durabilidad clínica. Métodos: Se fabricaron cincuenta muestras (N=50) de 2x2 cm de polimetilmetacrilato (PMMA) mediante el proceso de impresión CAD/CAM aditiva, divididas en Grupo Control (GC), Corega Tabs 3 minutos (G1), Corega Tabs Blanqueamiento (G2), Efferdent (G3) y Kin Oro (G4), con diez muestras por grupo. Se realizó una simulación de uso de 6 meses, basada en el tiempo de acción de cada pastilla de limpieza. Resultados: Se utilizó la prueba de normalidad de Kolmogorov-Smirnov, seguida de la prueba de Kruskal-Wallis. No hubo cambios significativos en la rugosidad de las placas oclusales después de la limpieza con las pastillas de limpieza (p > 0,05 para todas las mediciones). Conclusión: El uso de pastillas de limpieza para la higiene no provoca cambios significativos en la rugosidad superficial de las placas de PMMA, lo que sugiere una buena compatibilidad del material en las condiciones de laboratorio evaluadas.
