“…e.g., electrochemical, ion implantation and heat treatment, etc. 27 Titanium anodizing improves the surface properties which increases the lubricity, anti-galling and fatigue properties of the alloy. Because of the aforementioned properties, anodizing is becoming rapidly popular in treating components used in the medical industry, especially on orthopaedic implants.…”

Dental implants are mechanical components that are used to restore the mastication (chewing) function and/or aesthetic appeal because of tooth loss or degradation. They are affixed (screwed) into the upper or lower jaw and act as a base for single or bridge-type tooth replacements. They are mostly manufactured from titanium alloys. The surface integrity of the manufactured implant may have a significant effect on the functioning and success of the implant. A systematic review is described on the effect of engineered surface integrity on the performance of titanium dental implants as regards the implant fixation, mechanical performance, bone growth and cell response. The need for surface engineering of the implant is introduced first. This includes the mechanical, surface-integrity and biocompatibility-required properties. This is followed by introducing and discussing the dedicated surface-modification processes currently employed. These include: abrasive blasting, electrochemical processes, hybrid processes and laser modification. The mechanical and biocompatible properties of an implant are the most crucial factor for their application in biomedical use. Hence, the present review article focused on the latest improvements to dental implant design based on the mechanical and biocompatible properties. The physical contact of an implant with respect to its surface roughness is an important factor in dental implant design. The surface roughness of an implant on the macro, micro and nano scales have specific effects on the implant's contact with the surrounding tissue of the bone. In addition, the biocompitability of titanium material is very important to develop a sustainable dental implant. Looking into the importance of the above mechanical and biocompatible properties of bone implants, the authors review elaborately the development of titanium-based implants with reference to the above properties.

Pritrjeni (privija~eni) so v zgornjo ali v spodnjo~eljust in slu`ijo kot osnova za nadomestni zob ali za mosti~ek. Ve~inoma so izdelani iz titanovih zlitin. Integriteta povr{ine izdelanih vsadkov lahko pomembno vpliva na delovanje in uspe{nost vsadka. Opisan je sistemati~en pregled o vplivu in`enirske celovitosti povr{ine na zmogljivost titanovega dentalnega vsadka glede na pritrditev vsadka, mehanske zmogljivosti, vra{~anja kosti in odziva celic. Najprej je predstavljena potreba po obdelavi povr{ine vsadka. To vklju~uje zahtevane mehanske lastnosti, celovitost povr{ine in biokompatibilnost. Temu sledi predstavitev in razlaga trenutno uporabljanih postopkov za namensko spremembo povr{ine. To vklju~uje: abrazivno peskanje, elektrokemijske procese, hibridne procese in modifikacijo z laserjem. Mehanske in biokompatibilne la...

“…However, up to now, most of the microscale structures of the hierarchical micro/nano-textured surfaces, fabricated by acid etching [11,22,24,25], sand-blasting [26], electro-eroding [27][28][29] or some combination of them [30], have usually been unordered and irregular and may be adverse to the further improvement of their bioactivity [12,31,32]. An unordered structure will lead to insufficient synergistic functions in the interaction between cells and biomaterials [9].…”

“…The electrolyte condition distinctly influenced the wettability of the surface, as the result was published by Huan et al. [ 26 ] when the contact angle values of NiTi alloy decreased to 70° for 15° after anodizing with hydrofluoric acid because the surface becomes more hydrophilic with the nanotubular morphology. SFE has an inverse tendency in relation to the contact angle: that is, the smaller the contact angle values, the higher the SFE.…”

Objectives Development of a new generation of stable β alloy, free of aluminum or vanadium and with better biological and mechanical compatibility and evaluate the surface properties of Ti–6Al–4V and Ti–35Nb–7Zr–5Ta after anodization in hydrofluoric acid, followed by deposition of different electrolyte concentrations of magnesium particles by micro arc-oxidation treatment. Methods Disks were anodized in hydrofluoric acid. After this first anodization, the specimens received the deposition of magnesium using different concentration (8.5% and 12.5%) and times (30s and 60s). The surface morphology was assessed using scanning electron microscopy, and the chemical composition was assessed using energy dispersive x ray spectroscopy. The surface free energy was measured from the contact angle, and the mean roughness was measured using a digital profilometer. Results Anodization in hydrofluoric acid provided the formation of nanotubes in both alloys, and the best concentration of magnesium considered was 8.5%, as it was the condition where the magnesium was incorporated without covering the morphology of the nanotubes. X-ray dispersive energy spectroscopy showed magnesium incorporation in all conditions. The average roughness was increased in the Ti–35Nb–7Zr–5Ta alloy. Conclusions It was concluded that anodizing could be used to deposit magnesium on the surfaces of Ti–6Al–4V and Ti–35Nb–7Zr–5Ta nanotubes, with better results obtained in samples with magnesium concentration in 8.5% and the process favored the roughness in the Ti–35Nb–7Zr–5Ta group.
