Hydroxyapatite for Thermal Spray Technology
What is Hydroxyapatite?
Hydroxyapatite is the major component, and an essential ingredient, of normal bone and teeth. The osseointegration of an implant can be accelerated by a hydroxyapatite coating. The ingrowth process time of the HA-coated prosthesis is identical to the healing process of a bone fracture.
Medicoat offers a wide range of sintered and crushed hydroxyapatite powders adapted for thermal spray technology with irregular grains as well as agglomerated powders with spherical grains.
