Recent advancements in the surface treatments for enhanced biocompatibility and corrosion resistance of titanium-based biomedical implants

Abstract

Titanium-based biomedical implants are widely used owing to their biocompatibility, corrosion resistance and mechanical strength. Although, they still face challenges such as poor osseointegration and implant failure caused by corrosion. To address these challenges, various surface treatments have emerged to enhance the biocompatibility and corrosion resistance of titanium implants. This review article presents a concise overview of the innovative surface treatments for enhanced corrosion resistance and biocompatibility of titanium-based biomedical implants. The surface treatment briefly discussed includes physical, chemical, and biological treatments, such as plasma spraying, anodization, electrochemical deposition, and biomimetic coating. Furthermore, this article also highlights the importance of surface treatments to enhance the biological performance of titanium-based implants. This review provides insights for researchers and clinicians in the field of titanium-based biomaterials and may contribute to the development of more effective and durable biomedical implants.
