“…This native oxide film can prevent the metal from further reacting with corrosive environments [3]. Unfortunately, these films have many defects, only a few nm in thickness [4]. What is more, according to Hanawa et al [5], the oxide film formed in air is composed of Ti 4+ , Ti 3+ , Ti 2+ and metallic Ti 0 .…”

Anodic oxidation treatment of commercially pure titanium was carried out at the voltages of 10, 30, 50 V in 0.5 M H2SO4 solution at the potentiodynamic-aging mode so as to obtain the effects of the anodic potential on the surface characteristic and corrosion resistance of the anodic oxide film. The influences of potential on the surface morphology, the roughness, the crystalline behavior, the chemical composition and the corrosion resistance of the anodic oxide films were investigated by using scanning electron microscopy (SEM), atomic force microscope (AFM), Raman spectrum, X-ray diffractometry (XRD), X-ray photoelectron spectroscopy (XPS), potentiodynamic polarization curves and electrode impedance spectroscopy (EIS). The results show that increasing anodic potential at the potentiodynamic-aging mode can significantly enhance thickness, flatness, crystallization, chemical stability, and corrosion resistance of anodic oxide film.

“…The genuine biocompatible surface on the Ti dental implant is Ti oxide (TiO2), not Ti itself, which is spontaneously formed when the Ti surface is exposed to the atmosphere. However, this Ti oxide layer is very thin (a few nm in thickness) and is imperfect with defects [23]. Also, chemically unstable In distance osteogenesis, the direction of bone formation is from the existing bone to the implant; (B) in contact osteogenesis, however, the direction is opposite, from the implant to the existing bone, which is known not to occur on the turned Ti (Titanium) surface without any modification.…”

Modifications of Dental Implant Surfaces at the Micro- and Nano-Level for Enhanced Osseointegration

2019

This review paper describes several recent modification methods for biocompatible titanium dental implant surfaces. The micro-roughened surfaces reviewed in the literature are sandblasted, large-grit, acid-etched, and anodically oxidized. These globally-used surfaces have been clinically investigated, showing survival rates higher than 95%. In the past, dental clinicians believed that eukaryotic cells for osteogenesis did not recognize the changes of the nanostructures of dental implant surfaces. However, research findings have recently shown that osteogenic cells respond to chemical and morphological changes at a nanoscale on the surfaces, including titanium dioxide nanotube arrangements, functional peptide coatings, fluoride treatments, calcium–phosphorus applications, and ultraviolet photofunctionalization. Some of the nano-level modifications have not yet been clinically evaluated. However, these modified dental implant surfaces at the nanoscale have shown excellent in vitro and in vivo results, and thus promising potential future clinical use.

“…The whole preparation process is illustrated in Figure 1. At the beginning, the prepared samples were ultrasonically cleaned in acetone, degreased in a mix solution of NaOH (40 g/L), Na 2 SiO 3 (25 g/L), Na 2 CO 3 (25 g/L) and Na 3 PO 4 (40 g/L) for 20 min at 50 • C, and activated in a solution of NaOH (10 g/L) and H 2 O 2 (50 mL/L) for 15 min at 40 • C [31]. After each step, all samples were rinsed in deionized water and dried in warm air.…”

In this study, we introduced a novel environmentally-friendly electrolyte consisting of polytetrafluoroethylene (PTFE) nanoparticles and malic acid solution to fabricate composite anodic film on Ti-10V-2Fe-3Al alloy at different electrolyte temperatures. The morphology revealed that the PTFE nanoparticles were successfully incorporated into composite anodic films and embedded preferentially in the pores and cracks. Their performances (wear, corrosion and hydrophobicity) were evaluated via electrochemical tests, ball on disc tests, and a contact angle (CA) meter. Compared to the substrate of titanium alloy Ti-10V-2Fe-3Al, the composite anodic films exhibited the low wear rates, high corrosion resistance and good hydrophobicity. However, the microstructure and morphology of the films were affected by the electrolyte temperature. As a result, their performances were changed greatly as a function of the temperature and the film fabricated at 20 °C exhibited better performances (CA = 131.95, icorr = 6.75 × 10−8 A·cm−2, friction coefficient = 0.14) than those at other electrolyte temperatures. In addition, the corresponding lubrication mechanism of the composite anodic films was discussed.
