Towards Load-Bearing Biomedical Titanium-Based Alloys: From Essential Requirements to Future Developments

Topic Information

Dear Colleagues,

In the realm of biomedical research and clinical applications, metallic materials have garnered significant attention for their potential to enhance human health and longevity. Among these materials, titanium-based alloys stand out for their exceptional properties in addressing bone health issues in an ageing population. This Topic delves into the microstructure, properties, and processing techniques of titanium-based alloys, exploring various surface modification strategies to improve biocompatibility, wear resistance, and corrosion resistance. Special emphasis is placed on how additive manufacturing can revolutionize the development path of titanium-based alloys. We welcome submissions ranging from innovative technical developments and reviews to case studies and analytical assessments from various disciplines that are relevant to the support theory and technology of biomedical metallic materials, with a special focus on titanium-based alloys.

Implants made of titanium and its alloys are currently widely used in the human body. A series of surface modification methods developed nowadays enable titanium alloy implants to serve effectively in the human body for a long time. This paper reviews three different types of surface modification technologies for biomedical titanium alloys: physical, chemical, and biological, with particular attention to the assistance of these three technologies on the biological properties of titanium alloys. The physical method can change the surface morphology of titanium implants and prepare specific coatings for the implants, such as oxide films, bioactive molecules, drugs, etc. Chemical and biological surface modification technologies can minimize bacterial adhesion on the implant surface, improve the integration of soft tissue around the implant, prevent the occurrence of peri-implantitis, and accelerate the process of damage repair. An ideal titanium implant surface should balance the optimal surface morphology, chemical properties, and bionic characteristics to accelerate bone integration, enhance stability, and reduce peri-implant inflammation. Future research should focus on combining technologies, exploring interactions at the cellular and molecular levels, and conducting extensive in vitro and in vivo studies to verify the effectiveness and safety of modified surfaces. The progress in these fields will help overcome the existing limitations, improve the performance of implants, and obtain better clinical results. Full article
