“…However, the life quality of patients could be improved by using biomaterials that may interact with biological systems having minimal flaws and long service; therefore, they may be used for manufacturing human body implants [4]. Alloplastic implants using synthetic biomaterials have become a good choice because of their high immunological compatibility, easy way to obtain, and high availability in the materials commercial market [5].…”

Titanium (Ti) is a material frequently used in orthopedic applications, due to its good mechanical properties and high corrosion resistance. However, formation of a non-adherent fibrous tissue between material and bone drastically could affect the osseointegration process and, therefore, the mechanical stability of the implant. Modifications of topography and configuration of the tissue/ material interface is one of the mechanisms to improve that process by manipulating parameters such as morphology and roughness. There are different techniques that can be used to modify the titanium surface; plasma electrolytic oxidation (PEO) is one of those alternatives, which consists of obtaining porous anodic coatings by controlling parameters such as voltage, current, anodizing solution and time of the reaction. From all of the above factors, and based on previous studies that demonstrated that bone cells sense substrates features to grow new tissue, in this work commercially pure Ti (c.p Ti) and Ti6Al4V alloy samples were modified at their surface by PEO in different anodizing solutions composed of H2SO4 and H3PO4 mixtures. Treated surfaces were characterized and used as platforms to grow osteoblasts; subsequently, cell behavior parameters like adhesion, proliferation and differentiation were also studied. Although the results showed no significant differences in proliferation, differentiation and cell biological activity, overall results showed an important influence of topography of the modified surfaces compared with polished untreated surfaces. Finally, this study offers an alternative protocol to modify surfaces of Ti and their alloys in a controlled and reproducible way in which biocompatibility of the material is not compromised and osseointegration would be improved.

“…Titania nanotubes, formed by anodic oxidation, are a candidate method for the modification of the surface of titanium implants to enhance bone formation function. It is well known that nanotubes can be produced by anodizing flat titanium specimens [22][23][24][25], some studies [5,19] report nanotubes growth on the wire, meshes or curved surfaces. Very few [26,27] works deal with the use of complex geometry samples.…”

Self-organized TiO 2 nanotube layer has been formed on titanium screws with complex geometry, which are used as dental implants. TiO 2 nanotubes film was grown by potentiostatic anodizing in H 3 PO 4 and HF aqueous solution. During anodizing, the titanium screws were mounted on a rotating apparatus to produce a uniform structure both on the peaks and on the valleys of the threads. X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive X-ray (EDX) and electrochemical characterization were used to evaluate the layer, chemical composition and electrochemical properties of the samples. Aging in Hank's solution of both untreated and nanotubes covered screw, showed that: (i) samples are covered by an amorphous oxide layer, (ii) the nanotubes increases the corrosion resistance of the implant, and (iii) the presence of the nanotubes catalyses the formation of chemical compounds containing Ca and P.

“…Anodically grown titania nanotube arrays are an attractive material that has found a broad span of applications in photocatalysis [1], gas sensing [2], energy conversion [3] and storage [4][5][6], and biomedicine [7], each application with particular morphology requirements. Another appeal of this material is that morphology can be easily tuned by adjusting the anodization parameters, particularly applied electric field, bath composition and temperature.…”
