Obtención de compuesto de titanio con gradiente de porosidad mediante técnica pulvimetalúrgica

Abstract: RESUMEN En el estudio de biomateriales de uso implantológico para la fabricación de distintos tipos de prótesis, el titanio es un metal que ha sido utilizado exitosamente debido a su buena resistencia a la corrosión y a su buena resistencia mecánica. A pesar de los avances realizados, en la actualidad aún subsisten algunos problemas con este material en aplicaciones de reemplazo óseo debido al alto valor de módulo elástico de este metal (110 GPa) en relación al del hueso cortical (20-30 GPa) y al hueso trabecu… Show more

“…In order to achieve this purpose, coatings of calcium phosphates, oxides, hydroxides, and titanates have been used [6][7][8][9]. Also, the modification of the surface roughness and (or) topography has been successfully employed to enhance bioactivity on titanium and its alloys [7,10]. It is known that surface roughness influences the adhesion, growth, and cell proliferation processes [11,12].…”
