“…Streptococcus sanguinis (IAL 1832) stationary-phase cultures, a usual initial colonizer in implant surfaces, were grown overnight in brain heart infusion (BHI) to reach exponential growth . Subsequently, the optical density was adjusted to OD 600 = 1.00 ± 0.02 using a spectrophotometer (Multiskan; Thermo Scientific, Finland), representing a final suspension of 10 7 cells/mL .…”

“…It has been found that materials with a combination of micro-and nanostructured surfaces with a certain roughness can show improved levels of cell attachment [13]. Methods such as sandblasting and acid etching [14,15], anodic oxidation [16], plasma spraying [17], magnetron sputtering [18], or meniscus-dragging deposition [19] are commonly used for surface modification. These methods assume contact with the material, so they have some limitations to their universal use such as limitations in substrate size or contamination with hazardous chemicals [20].…”

Titanium and its alloys are commonly used in modern implantology. Cell viability on the surface of titanium implants depends on the surface topography, roughness, and wettability. Laser treatment is a successful method to control the surface morphology.The aim of this study was to comprehensively investigate the effects of laser ablation on titanium surfaces and their interactions with cells and bacteria. Cell adhesion, proliferation, and bacterial retention on smooth and laser-textured samples of commercially pure and nanostructured titanium of two grades were evaluated. Femtosecond laser treatment effectively enhances the wettability. Titanium grade four exhibits superior adhesion and proliferation rates when compared to titanium grade two. The cytotoxicity of nanostructured titanium is significantly lower, regardless of the surface treatment. Laser treatment resulted in increased short-term cell proliferation on grade two titanium and long-term cell proliferation on nanostructured grade two titanium only. Although the laser ablation has a limited effect on bacterial adhesion, the coverage of less than 1% in most samples indicates that the material itself has an antibacterial effect on the bacterial strain S. oralis.These findings provide valuable insights into how different material structures and surface treatments can affect cellular response and antibacterial properties for potential use in dental implantology.

“…In the recent decades, Ta has been shown to be a promising material for biomedical applications owing to its impressive ductility, wear resistance, chemical inertness, acid and alkali corrosion resistance, and in vivo bioactivity. These characteristics allow Ta to form chemical bonds with bone tissue, thereby initiating the biomineralization kinetics and optimizing the osseointegration process [8][9][10]. Moreover, since the 1940s, Ta has been used both in vitro and in vivo in various forms of medical instruments such as rods, wires, artificial joints, spinal fusion cages, dental implants, micro-or nano-particles, and radio markers [11].…”

“…The introduction of Ta into coatings via surface modification technologies is a reliable way to improve the surface and biological properties of biomedical metallic materials [8,10,[13][14][15]. For example, Hee et al [15] used a filtered cathodic vacuum arc deposition technique-the socalled bio-stable surface treatment-to prepare Ta and related nitride films on TC4 alloy, after which both the Ta and TaN films exhibited improvement in corrosion resistance.…”

Comparative Study on Wear Behaviors of Monolayer and Heterogeneous Multilayer Ta Coatings in Atmospheric and SBF Environments

Monolayer Ta and multilayer Ti/Zr/Ta and Zr/Ti/Ta coatings were prepared by magnetron sputtering on TC4 substrates to improve the surface friction and wear properties in a simulated body fluid (SBF) environment and an atmospheric environment. Optical microscopy, scanning electron microscopy, laser scanning confocal microscopy and nano scratch testing were employed to establish the structure-property-environment relationships. By controlling the preparation parameters, the outermost layer of all three samples was Ta coating, and the total coating thickness of each sample was about 3 μm. Friction and wear testing revealed that, compared to bare TC4 substrate, and multilayer Ti/Zr/Ta and Zr/Ti/Ta coatings, the monolayer Ta possessed the lowest friction coefficient as well as the minimum wear rate (i.e., calculation result of the wear track width and wear depth). This was mainly attributed to excellent adhesion strength, a particular structure and solid lubrication of the monolayer coating. The same coating sample exhibited a stronger wear resistance in the SBF environment than in the atmospheric environment. Furthermore, the wear behaviors and mechanisms of various coatings under different experimental environments are also discussed.
