Title
(EN) ELECTRICAL STIMULATION DENTAL DEVICE
(FR) DISPOSITIF DENTAIRE DE STIMULATION ELECTRIQUE
Abstract
(EN)
An electrical stimulating dental device (39) for electrically stimulating the periodontium bone region (34) within the mouth of a patient. The dental device includes a power supply system (45) for producing an electrical current. The power supply system may provide for a DC current (Fig. 11) or in one of the embodiments provide for a pulse electromagnetic wave generation (Fig. 12). A first electrode (43) defining a cathode element is electrically coupled to the power supply system (45) 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 (42) 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 (24, 27) and second (24, 27) cathode electrode elements are interfaced with opposing transverse sides of the gingivae lining for passage of the current therethrough. Anode electrode elements (42, 9) may be placed in interfacing contact with the lip, cheek or pallet of the user. By passage of an electrical current of a predetermined value the dental device (39) stimulates osteogenesis in the neighborhood of the cathode element (43).
(FR)
Dispositif electrique dentaire de stimulation pour stimuler electriquement la partie osseuse de la periodonte (34) dans la bouche du patient. Ce dispositif dentaire comprend un systeme d"alimentation (45) en courant electrique. Le systeme peut fournir du courant continu (figure 11) ou dans l"une des realisations peut prevoir la production d"ondes electromagnetiques pulsees (figure 12). Une premiere electrode (43) definissant un element cathodique est couplee electriquement au systeme d"alimentation (45) et forme, selon une modalite du dispositif, un interface avec la surface de la gencive dans la bouche du patient. Un second element d"electrode (42) est couple electriquement au systeme d"alimentation et peut etre couple a une partie eloignee du corps du patient. Dans une autre modalite de l"invention des premiers (24, 27) et seconds (24, 27) elements cathodiques d"electrode forment des interfaces avec des cotes opposes de la surface de la gencive, tout en etant places transversalement par rapport a celle-ci pour y faire passer un courant. Des elements d"electrode anodiques (42, 9) peuvent etre places en contact formant interface avec la levre, la joue ou le palais de l"utilisateur. Le dispositif dentaire (39) stimule, par le passage du courant d"une valeur predeterminee, l"osteogenese dans le voisinage de l"element cathodique (43).
