Abstract
Abstract An electrical stimulating dental device for electrically stimulating the periodontium bone region within the mouth of a patient. The dental device includes a power supply system for producing an electrical current. The power supply system may provide for a DC current or in one of the embodiments provide for a pulse electromagnetic wave generation. A first electrode defining a cathode element is electrically coupled to the power supply system and in one form of the device interfaces with the surface of the gingivae lining within the mouth of the patient. A second electrode element is electrically coupled to the power supply system and may be coupled to a remote portion of the body of the patient. In another form of the invention, first and second cathode electrode elements are interfaced with opposing transverse sides of the gingivae lining for passage of the current therethrough. Anode electrode elements may be placed in interfacing contact with the lip, cheek or palate of the user. By passage of an electrical current of a predetermined value the dental device stimulates osteogenesis in the neighborhood of the cathode element.
