[ IONGUARD® ION IMPLANTATION ]

N2 Biomedical’s proprietary IonGuard® ion implantation process utilizes direct ion beam bombardment to create a hard, low friction, and hydrophilic surface without adding a coating layer to the surface or changing the bulk properties of the device. This low temperature process has been used to treat millions of medical device implants including metal knees and hips and orthodontic arch wires.

Ion implantation is a highly controllable process for modifying physical and chemical surface properties of materials. Many surface properties can be improved with ion implantation including hardness, wear resistance, resistance to chemical attack, and reduced friction. The process can be applied to virtually any material, including most metals, ceramics and polymers.

The process is extremely controllable and reproducible and can be tailored to modify different surfaces in desired ways.

Reduced Wear and Fretting with IonGuard

IonGuard® treated Titanium knees show wear properties comparable to Co-Cr devices in a 3 million cycle wear study. IonGuard® treated Titanium hip components release 35 times less metal than untreated parts after 1 million wear cycles.

IonGuard® -treated Co-Cr heads remain up to 29% smoother than untreated heads in clinical usage. Multiple clinical studies with multi-year follow-up have demonstrated up to a 40% reduction in wear rates for mating polyethylene surfaces. IonGuard® -treated Co-Cr heads have shown superior performance in a 5 million cycle wear simulation test as compared to TiN-coated Co-Cr and  comparable wear to ceramic-based heads.

Increased Lubricity with IonGuard

N2 Biomedical’s proprietary IonGuard® surface treatments and IBAD NanoCoatings can be engineered to reduce surface friction and improve hydrophillicity on a variety of polymer, metal and ceramic substrates. Our highly adherent coatings reduce the surface friction and tackiness without changing the bulk properties of the device.

Written by Nader M. Kalkhoran

The increasing awareness and growing concerns about metal ion release and patient hypersensitivity reactions have renewed interest in titanium for orthopedic implants, such as knee, hip and extremity joint replacement. This whitepaper covers:

  • Analysis of micro-hardness of titanium-based alloys treated using ion implantation
  • Results of femoral knee joint wear simulation studies
  • Wear comparison of untreated and ion implanted Ti-6Al-4V
  • Comparison of fretting wear depths for IonGuard-treated and untreated Ti-6Al-4V
  • Hydrophilicity and wettability comparison IonGuard®-treated and untreated Ti-6Al-4V
