Definitions

  • the utility model relates to medicine, dentistry and can be used for complex prevention and treatment of inflammatory processes in periodontal tissues and enamel demineralization phenomena, including those associated with the use of non-removable orthodontic equipment.
  • this individual device is intended for independent electrophoresis/galvanization procedures that accelerate the process of tooth movement during orthodontic treatment, as well as for the treatment and prevention of periodontal inflammation.
  • Electrophoresis is an electrokinetic phenomenon of movement of particles of a dispersed phase (colloidal or protein solutions) in a liquid or gaseous medium under the influence of an external electric field.
  • One of the well-known devices treatment with direct electric current is the use of a mouth guard containing a medicinal preparation.
  • a mouth guard for administering preparations using gum electrophoresis allows the preparations to be introduced directly to the site of inflammation, in a strictly dosed manner and for a certain time. With this method, the depth of penetration of the medicinal substance through the oral mucosa increases by 4-5 times.
  • Treatment of periodontal diseases using a mouth guard for administering medications using gum electrophoresis allows: to effectively influence the main pathogenetic mechanisms of periodontitis development in a short time, and to obtain a lasting therapeutic effect.
  • RU 2705621, A61C7/00, published 11.11.2019 describes a device for administering a drug through the gum, which includes two electrodes, each of which is made with an individual shape of adhesion to a specific area of the gum, and wires connected to an electrophoresis device.
  • electrodes are made from lead plates 1-2 mm thick, to which conductive conductors made of insulated copper wire up to 30-40 cm long are soldered in the middle. After this, an arched base is made into which the electrodes are fused. The finished device is put on top of the jaw teeth at the point where the drug is supplied. Such a device does not allow the jaws to close.
  • the disadvantage of this device is that after putting the device on the dentition, it requires sealing the cavity between the inner wall of the mouthguard and the gums. To do this, an insert is inserted into the mouthguard, which must have an exact repetition of the shape of the walls of the gums and the mouthguard. The issue of bringing the wires out is problematic; it is assumed that they can be brought out to the occlusal surfaces of large molars. To connect the terminal from the current source, the electrode has an output at the level of the occlusal surface of the teeth along the midline of the labial surface of the device. This leads to inconvenience in using the device, which requires precise adjustments.
  • Fig. 1 is a general view of the claimed dental device
  • Fig. 2 is an example of the arrangement of the gasket
  • Fig. 3 is an example of the implementation of the electrode in the form of a loose braided wire sheath
  • Fig. 4 is an example of the implementation of the electrode in the form of a thin metal plate.
  • a dental device for carrying out physiotherapy contains a dental mouth guard 1 made according to a model of the patient's jaw, U-shaped in plan and corresponding to the shape of the dental arch and adjacent soft tissues.
  • the mouth guard is installed/put on from above onto the dental row of the jaw.
  • Two electrodes 2 and 3 are mounted in the mouthguard, placed opposite each other on the inner surface of the cavity of the dental mouthguard. These electrodes are connected to wires 4 and 5, which carry contact connectors 6 on the end parts for connection to a source of direct current (not shown).
  • the mouthguard is made from thermoforming plates, which are used in the manufacture of aligners and retainers.
  • This is a plastic material made of medical multilayer polyurethane plastic.
  • the chemical composition is polyethylene terephthalate glycol, it can also be polyethylene terephthalate glycol or Duran, or others based on vinyl acetate, any variety of modern plastics for thermoforming aligners.
  • the pad is a hydrophilic material, a special sponge made of cellulose fibers, protecting the mucous membrane from electrolysis products that occur during therapeutic effects.
  • the fine spongy structure facilitates rapid uniform impregnation with the medicinal solution and its uniform release.
  • Fig. 2 shows an example of the placement of a gasket partially covering the surface of the recess. It is possible to use a gasket that completely covers the surface of the recess.
  • the mouth guard with a lining is clearly fixed on the jaw and ensures a tight and uniform fit to the mucosal surface with the help of the installed lining and/or the gel applied to it.
  • the wires are inserted from the outer surface of the mouthguard and pass through its body to the inner surface.
  • the ends of the conductive core of the wire are brought out to the inner surface of the mouthguard and act as electrodes that form an electric field.
  • the braided conductive core brought out along the inner surface of the mouthguard is an electrode and can be unbraided (fluffed up) with the distribution of the wires 10 that form it over the surface of the mouthguard (Fig. 3).
  • a contact plate 11, or a contact petal (Fig. 4) can be soldered to the end of the wire.
  • the wires of the conductive core are sufficient.
  • the wires do not touch the places of the gum mucosa exposed from insulation due to the use of a gasket that covers them.
  • the wires 10 or the plates 11 act as electrodes when interacting with the solution or gel, delivering the active substance to the tissue.
  • the contact plate or contact petals can be made of tin foil, sheet lead, tin, stainless steel, carbon-graphite fabric pressed into plastic, a metal plate poured into conductive rubber, rubber (conductive latex) and graphite (disposable graphitized paper plates).
  • the electrode wires are connected to the power supply or connectors of the electrophoresis device. Switch on and adjust the current strength with the regulator until a slight tingling sensation appears.
  • the procedure is performed using continuous direct electric current of low voltage (30-80 V) and low strength (up to 50 mA). Current density indicators are in the range from 0.02 to 0.3 mA/cm2.
  • Portable devices such as Potok, Elfor, Elfor Prof or other similar devices that generate direct or various types of low-frequency pulsed currents are used, for example, standard batteries.
  • the pad is moistened with a solution of the medicinal substance or moistened with water and the gel is applied.

Abstract

Ce modèle d'utilité se rapporte au domaine de la stomatologie. Ce dispositif stomatologique pour effectuer une physiothérapie comprend une plaque occlusale dentaire en forme de U réalisée selon un modèle de la mâchoire du patient, dans un plan correspondant à la forme de la rangée de dents et adjacent aux tissus mous pour l'installation depuis le haut sur la rangée de dents de la mâchoire, ainsi que deux électrodes disposées en face l'une de l'autre sur la surface interne du renfoncement de la plaque occlusale dentaire et connectées à des conducteurs venant se connecter à une source de courant continu. Une applique est fixée sur la surface du renfoncement s'étendant sur la longueur de la plaque occlusale dentaire et reproduisant la forme de la rangée de dents, laquelle est faite d'un matériau hydrophile ayant une structure spongieuse et est utilisée pour appliquer une préparation médicamenteuse; les électrodes sont disposées sous cette applique, et la plaque occlusale dentaire dans la région de positionnement des électrodes comporte une fente ouverte.
