TiO₂ Nanotube Coatings for Orthopedic Implants
Orthopedic implants—from joint replacements to bone screws—face critical challenges like infection, implant loosening, and delayed bone healing. These complications often stem from poor implant–tissue interactions and bacterial colonization.
TiO₂ Nanotube surfaces, developed by Schnaiffer through precision anodization of titanium, offer a transformative solution: they promote osseointegration, resist infection, and support local drug delivery, all at the nanoscale.
We manufacture high-purity TiO₂ nanotube arrays on medical-grade titanium substrates, ideal for integration into orthopedic implant systems, coatings, and clinical prototypes.
TiO₂ Nanotubes as Orthopedic Implants
Why TiO₂ Nanotubes for Orthopedic Implants?
- Improved Bone Integration: Encourages osteoblast adhesion and proliferation
- Reduced Infection Rates: Inhibits biofilm formation by pathogenic bacteria
- Drug-Eluting Capability: Allows sustained delivery of antibiotics or BMPs
- High Biocompatibility: Non-toxic, non-inflammatory, and corrosion-resistant
- Support for Functional Coatings: Ag, Zn, hydroxyapatite, peptides, etc.
Applications
- Hip and Knee Joint Replacements
- Spinal Implants and Rods
- Bone Screws and Plates
- Intramedullary Nails
- Trauma Fixation Devices
Our Fabrication Process
Schnaiffer’s process ensures uniform and adherent TiO₂ nanotube layers on orthopedic-grade Ti substrates:
- Substrate: Ti6Al4V ELI and CP Titanium
- Electrolyte: Fluoride-based solution
- Post-Annealing: to obtain anatase or rutile phase
- Optional Coatings
Our technology supports flat and curved geometries and is adaptable to specific implant designs.
Typical Challenges Solved
- Implant loosening and poor osseointegration
Nanotube surface enhances bone bonding
- Post-operative infections
Antibacterial coatings or drug-loaded tubes
- Limited bone healing
Growth factor delivery from nanotubes
- Need for revision surgeries
Increased long-term implant stability
