Claim:
A percutaneous bone conduction implant, comprising: a fixture configured to be anchored in the recipient's skull; and a skin-penetrating abutment configured to interface with the fixture and to permit the abutment to be removably attached to the fixture to form a fixture-abutment assembly, wherein at least one anti-microbial surface forms one or more surfaces of the formed fixture-abutment assembly located in an interior of the formed fixture-abutment assembly when the fixture is removably attached to the abutment with an abutment screw, the interior being substantially isolated from a surrounding environment of the fixture-abutment assembly, and wherein one of the fixture and the skin-penetrating abutment is seated within a cavity of the other of the fixture and the skin-penetrating abutment such that abutting surfaces of the fixture and the skin-penetrating abutment interface together to form a mechanically tight fit.
