“…Additionally, studies and analysis were carried out on titanium-zirconium alloys, which confirmed zirconium biocompatibility and the potential of titanium-zirconium alloys' corrosion resistance and mechanical durability [6,7]. However, with a huge number of articles describing etching methods and their effect on the osseointegration of titanium and titanium-based alloys [7][8][9] and zirconia (zirconium dioxide used as dental implant material) [10][11][12][13], there is little to no literature describing those processes and properties for zirconium-metal-based alloys. Zirconium and titanium have very similar mechanical properties to bones (Young's modulus and hardness), and also good corrosion resistance in the body environment [14].…”

The increased demand for implants that do not pose a threat to patients diagnosed using high-resolution magnetic resonance imaging and concerns arising from titanium allergies require the development of alternative implant materials. One promising concept is a use of zirconium as corrosion-resistant, nontoxic material that is lower in magnetic susceptibility. To achieve this, safe and efficient surface treatment methods of zirconium metal have to be developed. In this study, zirconium samples were treated with fluoride-free and fluoride-containing etching mixtures to determine their effect on the surface of Zr. SEM images were taken to investigate the preliminary effects of the etchants. Then, a second set of experiments was carried out using mixtures of HF-H2SO4 and ammonium persulfate–fluoride salts, as they gave the most promising results in the first trial. SEM images were taken and measurements on roughness, wettability, and atomic composition were made. The results showed an even zirconium surface in APS-fluoride salts, along with the formation of pits (1–3 μm) similar to those found in commercially available implants. There was no significant increase in the roughness of the treated samples. The addition of NO3− ions in the form of KNO3 speeded up etching and promoted pit formation. The HF-H2SO4 mixture was found to give unsatisfying results, as the surface was too rough and the formed pits were too large. It was concluded that etching zirconium in ammonium persulfate and fluoride salts is a promising area of research for the preparation of zirconium implants; however, further research has to be carried out on sandblasted samples.

“…Ti disks (Alfa Aeser by Thermo Fisher Scientific, US), 6.0 mm in diameter and 0.25 mm in thickness, were treated with concentrated hydrochloric acid HCl 37% (Merk, Germany) at 60 °C for 30 min, and disks were immersed and washed with distilled water and dried in the oven at 40 °C for 1 h (Etched Ti). [64] After surface modification, the disks were ultrasonically cleaned with acetone, ethanol and distilled water each for 10 min, and then allowed to air dry. The Ti disks were coated with a multilayer coating through sequential layering, resulting in multiple layers on top of each other.…”

The development of antibacterial coatings is a promising approach to preventing biofilm formation and reducing the overuse of systemic antibiotics. However, widespread antibiotic use has resulted in antibiotic‐resistant bacteria, limiting the efficacy of antibiotic‐based coatings. Herein, an antibacterial coating is developed by layer‐by‐layer (LbL) assembly of two polymers namely PDLG (poly (D,L‐lactide‐co‐glycolide)) and gelatin methacryloyl (GelMA) while chicken cathelicidin‐2 (CATH‐2), a cationic and amphipathic peptide, is loaded between these polymer layers. The electrospray method is used to apply the coatings to achieve efficient peptide loading and durability. The CATH‐2 bactericidal concentration ranges are first identified, followed by a study of their cytotoxicity to human mesenchymal stem cells (hMSCs) and macrophage cell lines. Later, different LbL electrospray coating assemblies loaded with the optimal peptide concentration are sought. Various coating strategies are investigated to identify an LbL coating that exhibits prolonged and biocompatible CATH‐2 release. The resulting CATH‐2‐coated titanium surfaces exhibit strong antibacterial activity against both Staphylococcus aureus and Escherichia coli bacteria for 4 days and are biocompatible with hMSCs and macrophage cells. This coating can be considered as a versatile delivery system platform for the delivery of CATH‐2 peptides while avoiding cytotoxicity, particularly for the prevention of infections associated with implants.

“…The chemical methods are by using acids or alkali solutions to change the surface roughness and to induce the wettability of the surface (li et al, 2002;Zareidoost et al, 2012;Al-radha and Al-radha, 2016). Another method is the physical treatment such as plasma or thermal spray (Wang, Khor and Cheang, 1998;lavos-Valereto et al, 2001;roy, bandyopadhyay and bose, 2011;robotti and Zappini, 2019).…”

Numerous biomaterials have been constantly researched upon for dental implants. We wanted to evaluate alternative elements that may have the potential to offer equivalent or superior osseointegration. One such element of interest is Hafnium. In the periodic table by IUPAC, tantalum belongs to period 6 (d block) of periodic table. Hafnium belongs to the same period and block as tantalum, in the periodic table. Various in vitro studies were conducted on hafnium metal. Studies have reported that hafnium has a similar response in soft and hard tissues in two different animal species (rat and rabbit), which suggests that hafnium might be an interesting material for biomedical applications. This review aims at analysing the existing literature on hafnium as potential implant biomaterial.
