| Abstract Scope |
This study investigates the use of polycrystalline diamond (PCD) coatings on 3D-printed titanium implants to improve their integration with bone tissue. While titanium implants are known for their mechanical strength and biocompatibility, they struggle to bond directly with bone due to a surface oxide layer. PCD coatings, with properties like exceptional hardness, chemical stability, nanoscale roughness, and antibacterial activity, offer a promising solution. In experiments with rabbit models, PCD-coated titanium implants demonstrated significantly enhanced bone integration, reduced inflammation, and stronger bonding compared to uncoated titanium. These findings suggest that PCD coatings could improve the long-term stability and effectiveness of orthopedic implants, addressing challenges such as infection risks and supporting better patient outcomes. This research marks a significant advancement in developing durable, biocompatible materials for orthopedic applications, meeting the needs of an aging population. |
