The propose of this review was to summarize the advances in multi-scale surface technology of titanium implants to accelerate the osseointegration process. The several multi-scaled methods used for improving wettability, roughness, and bioactivity of implant surfaces are reviewed. In addition, macro-scale methods (e.g., 3D printing (3DP) and laser surface texturing (LST)), micro-scale (e.g., grit-blasting, acid-etching, and Sand-blasted, Large-grit, and Acid-etching (SLA)) and nano-scale methods (e.g., plasma-spraying and anodization) are also discussed, and these surfaces are known to have favorable properties in clinical applications. Functionalized coatings with organic and non-organic loadings suggest good prospects for the future of modern biotechnology. Nevertheless, because of high cost and low clinical validation, these partial coatings have not been commercially available so far. A large number of in vitro and in vivo investigations are necessary in order to obtain in-depth exploration about the efficiency of functional implant surfaces. The prospective titanium implants should possess the optimum chemistry, bionic characteristics, and standardized modern topographies to achieve rapid osseointegration.

“…We could find that the characteristic band of MHA from the CS-MHA composite coating became less intense, and except for slight band shifts, these include the absence of O-H bending vibrational band at 635 cm −1 . On the contrary, the characteristic peaks of CS standing at 1643 amide I (C�O-NHR) disappeared, becoming less intense, which confirms the formation of possible electrostatic interaction and hydrogen bonding between the NH 3 + of CS and PO 4 3− of HA [30]. e FT-IR spectra of HNT-MHA-coated implant surfaces are shown in Figure 2(c).…”

“…Especially, Ti and its alloys are used in biomedical devices for internal fixation devices (such as pins, screws, bone plates, and others), among which orthopedic implant applications are relatively effective due to their low density, high strength, appropriate biocompatibility, and excellent corrosion resistance [3]. However, the surface of Ti alloy loses its efficiencies because the human body fluids leach out aluminum and vanadium ions; because of their inefficiency to form a chemical bond with bony tissue, loosening may occur over a long period, becoming a critical problem known as poor osteoconductivity; furthermore, a high concentration of these metal ions causes a negative effect on living organisms [4].…”

To develop the corrosion resistance and improve the biological performance of a titanium implant (Ti6Al4V alloy), a series of mineral (M = Zn and Mg)-substituted hydroxyapatite (MHA), chitosan-MHA (CS-MHA), halloysite nanotube-MHA (HNT-MHA), and HNT-CS-MHA composite coatings were fabricated on the anodized titanium alloy by electrodeposition. The surface morphology and cross section of various coated composites were investigated by high-resolution scanning electron microscopy (HR-SEM). Furthermore, the functional groups and phase structure of the composite coatings were investigated by Fourier transform infrared spectroscopy (FTIR) and X-ray diffractometry (XRD). Corrosion behaviors of the composite coatings were also investigated by polarization and impedance spectroscopy (EIS). Moreover, the cell-material interaction of the composite coating was observed in vitro with human osteoblast MG63 cells for cell proliferation at 1, 4, and 7 days of incubation. Consequently, HNT-CS-MHA-Ti may have potential applications in the field of orthopedic and dental implants.

“…However, mechanical tests indicate that the resultant HA coatings suffer poor mechanical properties (tensile strength, wear resistance, hardness, toughness, or fatigue), limiting its long-term application due to the relative movement between the implant and human bone, respectively. In order to overcome these mechanical limitations of HA coatings, the addition of different bioinert ceramic materials into HA matrix for reinforcement such as aluminum oxide [45,46], zirconia [45], mixture of titania and zirconia [47], yttria-stabilized zirconium [48], or nanodiamond particles [49] have been evaluated. A representative example can be found in [45] where two reinforced HA coatings with alumina (Al 2 O 3 ) and zirconia (ZrO 2 ), respectively, have been analyzed in order to investigate the microstructure, phase formation, and mechanical properties (hardness and tensile bond strength) as a function of as-sprayed coating and after postthermal treatment at 700°C for 1 h. The results indicate that after postcoating heat treatment, a dual effect has been observed such as an increase in the crystallinity and a decrease in the resultant porosity.…”

During the last two decades, numerous surface treatments have been developed to improve the biocompatibility of different types of prosthesis and other medical implants. Some of these devices are subject to demanding loading and friction conditions (e.g., hip, knee, and spine prosthesis). However, for other implants, there are more specific requirements as it happens for coronary stents or pacemaker electrodes. The materials used for the manufacture of the aforementioned devices are subjected to very high restrictions in terms of biocompatibility, in particular on chemical composition, corrosion resistance, or ion release. As a consequence, most of prosthesis and other implants are made of a limited number of materials such as titanium alloys, stainless steels, cobalt-chromium alloys, UHMWPE, or PEEK. Unfortunately, from a strict point of view, none of these materials meet all the requirements that would be desirable in terms of durability and prevention of infections and inflammatory processes. Coatings and other surface treatments have been developed to solve these problems and to improve biocompatibility. In this chapter, we present an updated review of the most used surface engineering technologies for biomaterials, like novel PVD coatings, ion implantation, and other plasma spray treatments, as well as a critical review of the characterization techniques. This study is completed with an insight into the future of the field.
