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. All adapted for thermal spraying technology.
