Abstract

Un método para fabricar un dispositivo biomédico para ajustar un defecto óseo, dicho dispositivo biomédico tiene una primera área osteoconductora con una porosidad controlada, que está en la periferia del dispositivo, que rodea y que limita una segunda área, la relación de la porosidad de la segunda área con la porosidad de la primera área es igual o menor de una, preferiblemente varía desde 0,001 hasta 0,9; el método comprende las siguientes etapas: - se realiza una imagen del defecto, - a partir de esta imagen, se diseña un objeto virtual con un software de diseño asistido por ordenador, - el dispositivo biomédico se fabrica por una tecnología láser directa que comprende estratificar un polvo de partículas sobre una placa (7) de tal manera que se forma una capa de un grosor predeterminado sobre la placa (7), y que tiene el haz de láser (8) procesando selectivamente el polvo para producir una capa procesada, y esto, Capa tras capa, las capas se unen hasta que se forma el dispositivo biomédico completo; en donde el polvo comprende cerámicas; metales; aleaciones de metal; vidrios bioactivos; titanato zirconato de plomo; polímeros biocompatibles o mezclas de los mismos; y en donde el polvo está libre de aglutinante.
