Dental crown and system for treatment of infected metallic dental implants

A dental implant includes a post and an abutment extending from the post, the post and abutment being made from metal. A crown having a hollow cavity is attached onto the abutment, the crown being configured with a metallic insert that can be accessed and coupled to the abutment to enable electrical contact. In one version, the crown includes a metallic core and in another version, the crown can include a formed recess that receives a portion of the metal abutment. In each version, an exposed metallic area is provided, enabling electrical conduction to the abutment and post as part of a bacterial treatment of the dental implant.
