Resumen

Este estudio caracterizó la topografía de implantes osteointegrados (Ti-cp) con superficie mecanizada (MS), superficie de rayo láser (LS) y superficie de rayo láser seguida de deposición de silicato de sodio (SS) mediante MER-EDX, medidas de rugosidad, corte transversal rugosidad, ángulo de contacto, difracción de rayos X (DRX) y perfilometría óptica confocal láser. El MER de MS mostró superficie lisa, contaminada con residuos de mecanizado, mientras que LS y SS superficies rugosas con un patrón morfológico más regular y homogéneo. El EDX mostró picos de Ti para MS y Ti y oxígeno para LS y SS. Los valores medios de rugosidad de LS y SS fueron estadísticamente más altos (p <0.05) que MS. El ángulo de contacto de LS y SS fue 0º. La DRX de MS mostró solo picos de Ti, mientras que LS y SS mostraron la presencia de óxidos y nitruros y presencia de silicato de sodio. El tratamiento superficial realizado en LS y SS promovió importantes modificaciones en la topografía y propiedades físico-químicas.
