English title:	Anodized nanostructured titanium surfaces: present and future
Spanish title:	Superficies de titanio nanoestructuradas: presente y futuro
English abstract:	Titanium and its alloys have been widely used as materials for implants with biomedical applications, due to their biocompatibility and their chemical, physical and mechanical properties, and very importantly, their corrosion resistance. The goal is that the implant does not fail and therefore that osseointegration occurs in the short term, which is defined as a direct, structural, and functional connection between living, ordered bone and the surface of a prosthesis subjected to functional load. It has been shown in recent years that osseointegration strongly depends on the nano-topography of the implant surface. For this reason, the formation of a passive film of titanium oxide on the metal surface is of vital importance, which increases resistance to corrosion and biological activity. The formation of this layer with the morphology of titanium dioxide nanotubes, through a controlled electrochemical anodizing process, improves the properties of the implant and these properties are strongly dependent on the process parameters. In this research work, we will discuss the most important aspects associated with this technology and future challenges. Finally, the research experiences carried out in Universidad Nacional Experimental Polit�cnica Antonio Jos� de Sucre, Venezuela, with other institutions will be presented.
Spanish abstract:	El titanio y sus aleaciones se han utilizado ampliamente como materiales para implantes con aplicaciones biom�dicas, por su biocompatibilidad y sus propiedades qu�micas, f�sicas, mec�nicas y muy importante la resistencia a la corrosi�n. El fin �ltimo es que el implante no falle y por ende que ocurra a corto plazo la osteointegraci�n, la cual es definida como una conexi�n directa, estructural y funcional entre el hueso vivo, ordenado, y la superficie de una pr�tesis sometida a carga funcional. Se ha demostrado en los �ltimos a�os, que la osteointegraci�n depende fuertemente de la nanotopograf�a de la superficie del implante. Por ello adquiere vital importancia la formaci�n de una la pel�cula pasiva de oxido de titanio en la superficie del metal, lo que aumenta la resistencia a la corrosi�n y la actividad biol�gica. La formaci�n de esta capa con morfolog�a de nanotubos de di�xido de titanio, a trav�s de un proceso controlado de anodizado electroqu�mico mejora las propiedades del implante y las mismas son fuertemente dependiente de los par�metros del proceso. En este trabajo de investigaci�n, discutiremos los aspectos m�s importantes asociados a esta tecnolog�a y los desaf�os futuros. Finalmente, se presentaran las experiencias de investigaci�n realizadas en la Universidad Nacional Experimental Polit�cnica Antonio Jos� de Sucre, Venezuela, en colaboraci�n otras instituciones.
