IonGuard®

Surface Treatment for Co-Cr and Ti Orthopedic Devices
  IonGuard®
   
IonGuard® is Spire’s proprietary approach for reducing polyethylene wear 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 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
