UA64971A - Device for joint stimulation of tissues in oral cavity - Google Patents

Abstract

The device for the joint stimulation of tissues in the oral cavity comprises the base consisting of two branches - upper and lower. The edges of each branch are flexed matching the transitional folds and extending over the edges of the base. The branches are made from the elastic conductive material consisting of two layers. The internal layer is thick and soft, while the external one is thin and rigid and comprises the dental bed. The flexed edges matching the transitional folds and extending over the edges of the base are designed as the soft winglets surrounded by the soft rolls. Each winglet contains the horseshoe-shaped electrode connected with the electrostimulator. The electrostimulator casing is attached within the upper branch of the base.

Description

The intended invention relates to medicine and sports, in particular to devices that are used for the prevention and treatment of human diseases by methods of using adequate motor activity, in particular for dental procedures.

There is a well-known rack for stretching the spine, which has a head holder suspended and spring-loaded on a movable rack in the form of a chin rest fixed on the patient's head /p.U. Me21158, А63В23/02, Bul. Me1, 1998/.

The disadvantage of this head holder, from the point of view of ensuring the load of the jaw muscles, is that it creates tension of these muscles only in a static plan - in the form of isometric stresses that do not provide dynamic movements of the jaw joints, which could more adequately affect on these muscles. In addition, the head holder cannot be used without support, which is a movable rack on a massive support. Therefore, this head holder is not suitable for stimulating oral cavity tissues during masticatory muscle exercises.

A known electrostimulation electrode that is connected to an electric stimulator and has an electrically stimulating conductive head connected to a holder made of conductive rubber / positive decision on the application

Me2001128686, dated 05/21/2002/.

The disadvantage of this electrode is that it is not suitable for stimulation of teeth, dental alveoli and other tissues of the oral cavity, because it has a different shape. In addition, its handle requires manual actions for fixation and movement, but this is unnecessary and unsuitable for the selected type of electrical stimulation.

There are widely known means and devices for biomechanical influence on various organs and systems of the human body, among which there may be a vibrator for the gums, created on the principle of electromechanical devices /book.

V.T. Nazarov, Biomechanical stimulation: Presence and hope, Minsk, "Polimya", 1986, p. 74-75/.

The shortcoming of this book and the description in the "Healthy teeth" section is that it does not contain specific devices for biomechanical stimulation of teeth in the treatment of caries, periodontal disease and other diseases of the oral cavity.

The closest in technical terms is a dental prosthesis, which contains a rigid base in the form of two branches - upper and lower, each of which has a soft layer with edges curved in the form of transitional folds, reduced in thickness, protruding beyond the base /p.M . Me39357, AbIS13/00, Bul. Me5, 20017.

The disadvantage of the prototype is that it does not have means for full-fledged dental gymnastics, that is, training the muscles of the jaws and for massaging the gums and other tissues of the oral cavity, which could be used for their strengthening, prevention and treatment of caries, periodontal disease and other diseases. as well as for the adaptation of patients to the use of dental prostheses.

The invention is based on the task, taking into account all the positive and negative qualities of the prototype - a dental prosthesis, to create such a device that would make it possible to increase the effect of dental gymnastics - training of the chewing muscles due to the creation of means of loading them, equipping them with mechanical massage and strengthening these means by using electrical and vibrational stimulation in order to improve the health of the teeth and the entire human body through the natural movement activity of chewing and to ensure the prevention and treatment of caries, periodontal disease and other now widespread diseases. This goal and task was supposed to be solved by using an elastic base with enhanced damping qualities, by gripping the alveoli of the teeth with elastic soft wings of their beds, which during chewing could create - the effect of stroking and squeezing - the most characteristic techniques of mechanical massage, and to strengthen these processes and accelerate electro and mechanical stimulation was used in medical procedures.

The task is solved by the fact that in a dental prosthesis, which contains a base of two branches - upper and lower, each of which has curved in the shape of transitional folds of the oral cavity, reduced in thickness and protruding edges beyond the base, according to the proposed invention, each branch of the base made of an elastic elastic conductive material, which has two layers: the inner one is softer and the outer one is harder, and has a bed for the teeth, and curved in the form of transitional folds, reduced in thickness and protruding beyond the base of the edges make up the side parts of this beds and are made of a soft layer in the form of wings surrounded by soft ridges, while each wing contains a horseshoe-shaped electric lead connected to an electric stimulator, the body of which is fixed in the middle of the upper branch of the base.

The technical and consumer result of the proposed device, which was achieved by using a combination of all its distinctive features, is that due to the execution of the base branches from elastic material of different elastic layers, it was possible not only to increase their shock-absorbing qualities and thereby increase the physical load on the muscles of the jaws, and provide mechanical massage of the alveoli and adjacent tissues of the oral cavity.

The use of an electric stimulator and the corresponding location of its electrodes in the branches of the base made it possible to significantly strengthen the effect of motor activity of the jaws and speed up the duration of training, preventive and therapeutic procedures.

The essence of what is proposed is explained by the drawing, where Fig. 1 shows the upper branch of the base of the device in axonometry and sections along A-A and B-B; in Fig. 2 - the same, the lower branch; on Fig. 3Z - a section of the upper branch of the base along A-A of Fig. 1; in Fig. 4 - the same, a section of the lower branch along A-A of Fig. 2; Fig. 5 - a side view of the base with the mouth open; in Fig. 6 - the same, with the mouth closed; Fig. 7 - section of the upper branch of the base along A-A of Fig. 1 in the initial state /left/ and during bite /right/, enlarged; in Fig. 8 - the same, a section of the lower branch of the base along B-B of Fig. 2; Fig. 9 is a schematic diagram of an electric stimulator and its connection to electrodes.

Specifically, the device for combined stimulation of oral cavity tissues has a base 1 made of two separate branches: upper 2 and lower 3, and an electrical stimulator 4 with electrodes 5.

Each branch of the base is made of a resilient elastic conductive material, allowed for long-term contact with oral cavity tissues, for example - from conductive rubber, in the form of a horseshoe - based on the impression of the patient's teeth. The elastic material of the branches has two elastic layers - the inner 6, which is thicker and softer, and the outer 7, which is thinner and harder.

An electric stimulator 4 is fixed in the middle of the branch 2, the body is fitted to the patient's palate using an impression.

Both branches of the base have beds 8 for placing the patient's teeth 9 in them and fixing them in the oral cavity.

The lateral parts of each lodge create elastic wings 10, which cover the teeth and alveoli of II teeth and, leaning against them and other parts of the oral cavity, reliably fix the branches in the mouth. These wings are reduced in thickness to their edges, and the edges themselves are made in the form of soft rollers 12. On top of each branch of the base, IZ contact plates are attached separately from each other, which are electrically connected to the electric stimulator 4 and through which current parcels are transmitted to the electrodes 5. Each electrode 5 is made in the form of an arc of electrostimulating material, which is fitted into the soft layer of each branch, in its wings 10, with the possibility of contact with the surfaces of dental alveoli 11 /fig. 1-8/. An ordinary electric stimulator is used, the body of which is adapted to the patient's palate and is connected electrically to the electrodes according to the diagram of fig. 9. Labial and buccal folds are indicated by positions 14 and 15.

Use the device in this way. First the lower 3, and then the upper 2 branches are placed in the mouth, placing them one on top of the other so that they lean tightly against each other plate 13, and the wings 10 of the branches cover the alveoli 11 and enter the labial 14 and oral 15 folds of the oral cavity with their ridges 12. At the same time, the electric stimulator is turned on and through the electrodes 5 electrical stimuli excite the tissues of the alveoli and other tissues of the oral cavity adjacent to them.

The physical load of the muscles of the jaw joints and the technical massage of the dental alveoli occur during active chewing actions: during the bite, the muscles contract and tense, and after the bite they relax. The elasticity of both layers of the branches ensures the necessary level of muscle tension. The inner soft layer 6 flattens, and the outer layer 7 is more brutal, covering the wings 10 on the outside, while elastically diverges. After biting, the muscles relax and both branches of the base - both upper and lower - return to their original position. Thus, when chewing, a physically demanding training of the muscles of the jaw joints is performed.

Mechanical massage during bites is provided by the fact that when the jaws are brought together, the pressure of the beds 8 and their wings 10 is created on the surfaces of the teeth and their alveoli resting on them, and after the bite, when the muscles relax, this pressure is removed, while blood circulation in the vessels of the alveoli is accelerated and adjacent tissues of the oral cavity, because chewing action creates a kind of pump-pump in their bloodstream, which more effectively supplies these structures with oxygen. Slow and weak movements of the jaws with small bite loads provide stroking of the massaging tissues, and more energetic and frequent movements create a means of extrusion. These massage techniques can be supplemented with vibromassage if the bites are performed with the maximum frequency. Then the blood circulation and all metabolic processes in the tissues of the oral cavity will proceed even more efficiently, which, together with physical exertion, will give a greater advantage and effectiveness to the procedures of prevention and treatment.

Electrical stimulation created by the electrical stimulator 4 and its electrodes 5 is important for shortening treatment procedures, ensuring and increasing their effectiveness. The combination of electrical stimulation with physical training and massage further enhances the preventive and curative effect on the tissues of the oral cavity, and vibromassage actions have a beneficial effect as well on the central nervous system.

Such a combined effect of these factors /physical movements, massage, vibration and electrical stimulation/, as is known, significantly increases the effects of prevention and treatment in general, and the tissues of the oral cavity in particular. Brushing your teeth, even if it is quite high-quality and systematic, cannot replace the effect that the combination of these factors gives.

Chewing gum, which is used for the prevention of dental diseases, cannot provide a reliable level, either in terms of the physical load of the muscles of the jaw joints, or in terms of the effect of massage on the tissues of the oral cavity. At the same time, it is dangerous, because in the case of flavor additives, it threatens to exhaust the salivary glands, which can negatively affect the quality of food absorption. The inclusion of electrical stimulation in this ensemble of physical activity and massage makes it possible to significantly reduce and strengthen the preventive and therapeutic effect, to remove the threat of metabolic disorders in the human body. This is precisely what gives the proposed device an advantage over the prototype.

We hope that the proposed device for combined stimulation of oral cavity tissue will find wide application in hygiene and medicine, especially it will be important for elderly patients.
