“…This could be attributed to the crystalline transformation of TNTs during annealing that closed the open pores of TNTs, thereby reducing the contact region of TNTs–electrolyte [ 103 ]. It is noteworthy that while annealing augments the corrosion resistance of TNTs, it can compromise the integrity of TiO 2 BL [ 104 ].…”

“…Additionally, during electrochemical tests, more Ca ions from Hank’s solution were sedimented onto the annealed TNTs to establish a protective Ca-containing crystal layer, which enhanced corrosion resistance of annealed TNTs post-implantation [ 105 ]. Moreover, continuously increasing the annealing temperature until 650 °C yielded dual anatase–rutile TNTs that improved their corrosion resistance compared to pure anatase–TNTs [ 104 ]. Hence, post-anodization annealing is recommended for achieving augmented chemical stability of anodized Ti implants.…”

Titanium is the ideal material for fabricating dental implants with favorable biocompatibility and biomechanics. However, the chemical corrosions arising from interaction with the surrounding tissues and fluids in oral cavity can challenge the integrity of Ti implants and leach Ti ions/nanoparticles, thereby causing cytotoxicity. Various nanoscale surface modifications have been performed to augment the chemical and electrochemical stability of Ti-based dental implants, and this review discusses and details these advances. For instance, depositing nanowires/nanoparticles via alkali-heat treatment and plasma spraying results in the fabrication of a nanostructured layer to reduce chemical corrosion. Further, refining the grain size to nanoscale could enhance Ti implants’ mechanical and chemical stability by alleviating the internal strain and establishing a uniform TiO2 layer. More recently, electrochemical anodization (EA) has emerged as a promising method to fabricate controlled TiO2 nanostructures on Ti dental implants. These anodized implants enhance Ti implants’ corrosion resistance and bioactivity. A particular focus of this review is to highlight critical advances in anodized Ti implants with nanotubes/nanopores for local drug delivery of potent therapeutics to augment osseo- and soft-tissue integration. This review aims to improve the understanding of novel nano-engineered Ti dental implant modifications, focusing on anodized nanostructures to fabricate the next generation of therapeutic and corrosion-resistant dental implants. The review explores the latest developments, clinical translation challenges, and future directions to assist in developing the next generation of dental implants that will survive long-term in the complex corrosive oral microenvironment.

“…TiO2 in the form of high-quality nanotube bundled structures has the potential to improve a broad range of applications' performance. It has a wide range of applications, namely solar cells [2,3], photocatalysis [4][5][6], as well as gas sensors. TiO2 (TNT) is an especially effective photocatalyst for hydrogen generation [7,8], photoelectrochemical cell since 1972 [9], and oxidation by electrocatalysis [10,11].…”

In this study, TiO2 nanotube arrays (TNTAs) are produced using an efficient, low-cost, and ecofriendly environmental anodization process in an electrolyte containing Glycerin. The TNTAs were annealed for 2 hours at 500 °C. X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), UV-Vis diffuse reflectance spectroscopy (DRS), photoluminescence (PL), and photoelectrochemical properties (PEC) were used to analyze the sample. According to the obtained findings, the photoelectrochemical response o f the TiO2 film was accomplished with a current density (Jph) of 0.196 mAcm -2 and photoconversion efficiency of 0.14 %.
