“…The coated sample also exhibited a reduction in pH from 10.5 to 8.5 after 7 days of immersion. (Kania et al (2020) compared TiO 2 deposition via sol-gel spin and sputter coating. Compared with the bare sample, the spin coated substrate showed more than four times the reduction in H 2 gas evolution while sputter coating showed only a marginal reduction.…”

The combination of light weight, strength, biodegradability, and biocompatibility of magnesium (Mg) alloys can soon break the paradigm for temporary orthopedic implants. As the fulfillment of Mg-based implants inside the physiological environment depends on the interaction at the tissue–implant interface, surface modification appears to be a more practical approach to control the rapid degradation rate. This article reviews recent progress on surface modification of Mg-based materials to tailor the degradation rate and biocompatibility for orthopedic applications. A critical analysis of the advantages and limitations of the various surface modification techniques employed are also included for easy reference of the readers.

“…The present trend in metallic biomaterial coatings is the formation of TiO 2 nanoparticles as a surface structure to protect the implant from corrosion. For instance, to protect an easily degraded biocompatible implant from corrosion, a magnesium based implant has been coated with TiO 2 particles [ 273 , 274 , 275 ].…”

Anodised titanium has a long history as a coating structure for implants due to its bioactive and ossified surface, which promotes rapid bone integration. In response to the growing literature on anodised titanium, this article is the first to revisit the evolution of anodised titanium as an implant coating. The review reports the process and mechanisms for the engineering of distinctive anodised titanium structures, the significant factors influencing the mechanisms of its formation, bioactivity, as well as recent pre-and post-surface treatments proposed to improve the performance of anodised titanium. The review then broadens the discussion to include future functional trends of anodised titanium, ranging from the provision of higher surface energy interactions in the design of biocomposite coatings (template stencil interface for mechanical interlock) to techniques for measuring the boneto-implant contact (BIC), each with their own challenges. Overall, this paper provides up-to-date information on the impacts of the structure and function of anodised titanium as an implant coating in vitro and in/ex vivo tests, as well as the four key future challenges that are important for its clinical translations, namely (i) techniques to enhance the mechanical stability and (ii) testing techniques to measure the mechanical stability of anodised titanium, (iii) real-time/in-situ detection methods for surface reactions, and (iv) cost-effectiveness for anodised titanium and its safety as a bone implant coating.

“…However, entirely inorganic sol-gel coatings are also proposed as protective layers enhancing both cytocompatibility and corrosion resistance of the coated implants. In particular, sol-gel ZrO 2 [130], ZrO 2 SiO 2 [131], Nb 2 O 5 [132] SrO-SiO 2 -TiO 2 [133], or TiO 2 -based coatings [134][135][136][137][138][139][140] have been proposed to improve the corrosion resistance of several metal substrates, such as steels [130,137,140], titanium grade 4 [131], Ti6Al4V [134,138], NiTi alloy [133,139], and Mg-based alloy [135,136]. Liu et al [67], Cheng et al [141], and Chiu et al [142] demonstrated that the presence of the sol-gel coatings improves NiTi alloy corrosion resistance reducing Ni release, which can cause allergenic and toxic effects when its concentration exceeds a certain level in the body.…”

The limited lifetime of implants entails having patients undergo replacement surgeries, several times throughout life in young patients, with significant risks for them and extensive cost for healthcare service. The overcoming of such inconvenience is still today a hard challenge for the scholars of the biomedical and biomaterial fields. The improvement of the currently employed implants through surface modification by coatings application is the main strategy proposed to avoid implants failure, and the sol-gel coating is an ideal technology to achieve this goal. Therefore, the present review aims to provide an overview of the most important problems leading to implant failure, the sol-gel coating technology, and its use as a strategy to overcome such issues.
