Abstract: An apparatus for use with a treatment system to disrupt bacteria from a metallic dental implant includes apparatus configured for mechanical and electrical connection to a device capable of producing an electrical stimulation voltage, and in which a connective body is further configured for attachment to the mouth of a patient and including at least one metal contact. The apparatus can include a mouth guard having at least one integrated or releasably attachable metal contact. Alternatively, at least one clip member can be attached, the clip member having a metal contact portion. The apparatus can be used in conjunction with any electrode of a treatment system in which the electrode is disposed within the mouth of the patient or external.

Abstract: 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.
