IonGuard® is Spire’s proprietary approach for reducing polyethylene and metallic wear debris through the direct ion beam treatment of articulating cobalt-chromium and titanium orthopedic devices.
The IonGuard process reduces wear by creating a hard, low friction, hydrophilic surface on the metallic device.
Benefits
- Improves hardness, wear and fretting resistance
- Increases surface energy (hydrophilicity)
- Reduces polyethylene and metallic wear debris
- Creates a low friction surface
- Improves corrosion resistance and reduces ion release
- Preserves bulk material properties
- Biocompatible and safe
Representative Applications
- Knee prostheses
- Hip prostheses
- Shoulder implants
- Elbow implants
- Dental implants
- Spinal screws
- Orthodontic archwires
- Finger joints
- Fixation devices
