La presencia de patógenos en los implantes médicos son una de las principales causas de morbilidad y mortalidad. El desarrollo de nuevos recubrimientos para la prevención de dichas infecciónes es una de las principales lineas de investigación actuales. En este articulo describimos la preparación de recubrimientos híbridos orgánico-inorgánicos para implantes óseos metálicos, basados en materiales sol-gel de probada capacidad osteogénica. Dichos recubrimientos presentan también diclorhidrato de octenidina (OCT) y diacetato de clorhexidina (CHX), dos bactericidad ampliamente utilizados en la prevención y eliminación de infecciones bacterianas. Los recubrimientos presentan buenas propiedades químicas y mecánicas, lo que los hace adecuados para su uso en dispositivos médicos. También demuestran una fuerte capacidad antibacteriana, dependiendo de la concentración del bactericida, no siendo tóxicos.
