“…High fatigue strength, on the other hand, can lead to a reduction in performance. [31][32][33] Surface colonisation and biofilm formation. Implants that specifically restrict bacterial adhesion and growth as well as the development of biofilms including advantageous host cell-surface interactions are highly desired.…”

Biological tissues in the body stop functioning normally at certain times due to genetic abnormalities, ageing, sickness, trauma, degeneration or accidents. Over the past few decades, biomaterials have been extensively used in the medical and dental fields. It is used as an alternate for natural bone with inflammation or mechanical integrity. The usages of biomaterials in various applications are implant materials, integral approach to promote healing of tissues, regeneration of tissues, probes and nanoparticles, biosensors and drug delivery system. Significant research and development are still being carried out for orthopaedic implants, dental screws, bone replacement, etc. Materials designed for biomedical applications have gone through three generations, with the first generation being bioinert materials, the second being bioactive and biodegradable materials and the third being molecular responses to materials (tissue level). Biocompatibility (biological and mechanical), corrosion resistance, wear resistance and osseointegration are factors to consider while using biomaterials for longer duration. Metals and their alloys, ceramics, polymers and composites are some bioimplant materials that are being used in the modern world. Some of the most important criteria for the selection or development of new biomaterials are kinds of oxide coatings generated on the surface and the mechanical properties of materials. The article reviews out categories of bioimplants and outlines the properties exhibited by various implant material, biological and mechanical factors favouring material selection, and few challenges shown by the materials.

“…It has been claimed that better mechanical characteristics (40% higher fatigue strength and tensile strength of 953 MPa) could be achieved by the application of this alloy in comparison with Ti-6Al-4V and cp Ti [72,73]. Improved osseointegration can be obtained by adding Zr to Ti [65], and enhanced biocompatibility is shown compared to pure titanium [74].…”

“…This alloy benefits from the unique advantage of the elasticity modulus closer to the human bone than that of conventional Ti alloys as well as admission strain (0.65%) near to human bones (0.67%). The incorporation of alloying elements such as Ta, Nb, and Zr enhances the alloy corrosion resistance and no adverse tissue reactions or toxicity is observed [74][75][76].…”

Owing to its good mechanical properties, enhanced wear resistance, good biological properties, biocompatibility, low cytotoxicity, and great corrosion behavior, Ti-Nb-Ta-Zr (TZNT) alloy, as new β titanium alloy, has attracted considerable attention for surgical implant applications. The need for the improvement of the implant properties in the physiological environment can be fulfilled by using the β titanium alloy with low elastic modulus. Additionally, this alloy can inhibit the surgical implant fracture, infection, inflammation, and the reaction of soft tissue with particulate debris. Therefore, the aim of this paper is to review the properties and applications of TZNT alloy as a promising choice for surgical implant applications.

“…There are several techniques used in this regard such as: sand blasting [21,22], etching [23], electrochemical treatment [24], and thermal spray coatings [25]. Amongst them, bio-ceramic coatings using, the hydroxyapatite (HAP -Ca 10 (PO 4 ) 6 (OH) 2 ) [26][27][28] are very promising for the modification of implant surfaces since they create strong bonding with bones [29][30][31]. One of the great advantages of the HAP is its great lifespan [32,33].…”

“…The calcium phosphate (CaP) ratio of HAP is 1.67 which is highly stable at a normal temperature and its pH ranges from 4 to 12. However, the properties and resultant applications of HAP depend on morphology, size, chemical composition and crystallinity [31]. In addition, it provides speedy and durable fixation to the host bones and possesses osseoconductive properties [34], protecting the metal surfaces from the environmental effects and thereby reducing the discharge of metallic ions from the implant surface to the host body.…”

Ti6Al4V alloy is a material with great strength, low-slung modulus, inferior density, and a virtuous blend of mechanical and exceptional corrosion resistance. However, it does not offer good osseointegration and bone development properties. Conversely, hydroxyapatite (HAP) is highly bioactive in nature to bind with the nearby bone tissues when implanted in the host body. In this work, we have extracted HAP from bovine bones by using the thermal decomposition method. This was followed by its deposition onto the Ti6Al4V alloy using the Electrophoretic Deposition (EPD) technique. TiO2 is used as a bond coat layer to increase the adhesion between HAP and Ti6Al4V alloy substrates. The coated samples after sintering exhibited excellent adhesion. This was followed by characterization using Scanning Electron Microscopy (SEM) and Fourier Transformed Infrared Spectroscopy (FTIR). FTIR and SEM confirm the formation of HAP and its presence after the immersion in SBF. Vicker hardness tester confirms the increase in hardness value of coated samples up to 35%. Potentiostat tests were conducted to compare the corrosion rate of both samples. In addition, the particle sizes were also identified by a laser particle analyzer, whereas X-Ray Diffraction (XRD) technique was also used to determine the crystalline phases of alloy and HAP.
