TPS Coatings

Long term implant stability following osseointegration?


Porous coated surfaces aid optimal osseointegration

DOT produces TPS coatings on implants in a vacuum chamber. An inert gas mixture (argon) is ionized in an ultra high temperature plasma flame. The gas heats up and expands rapidly after being expelled at high speed through a nozzle shaped anode. At the same time, titanium powder is injected into the plasma flame and it begins to melt.

Propelled at a high speed, the molten titanium particles strike the substrate surface, cool down rapidly, and fuse to the implant surface. The resultant porous layer is comprised of multiple layers of particles.

DOT has coated more than 2.3 million orthopedic and dental implants for implant manufacturers in Germany and worldwide using the Titanium Plasma Spray (TPS) process since 1997.

The robot controlled Titanium Plasma Spray (TPS) process creates a highly reproducible porous coating. DOT’s TPS coating complies with FDA guidelines for plasma sprayed coatings on orthopedic implants.
Sample devices with a strong history of TPS coating utilization:
  •         Hip joint, knee joint, ankle joint, shoulder joint
  •         Wrist, finger implants
  •         Spinal implants
