Abstract

The utility model relates to the field of medicine, and more particularly to orthodontology, and can be used for accelerated movement of the teeth together with the alveolar process on the upper jaw or the lower jaw, individually or together, using a device. The technical result of the proposed utility model is an increase in the ease of performing an electrophoretic procedure as a result of a modified mouth guard-electrode design that allows a snugger fit in the oral cavity and an even distribution of electrical potential across the surface of the electrode. To achieve this technical result, an improved model of a mouth guard-electrode for performing procedures in the oral cavity, more particularly electrophoretic procedures, is proposed, which consists of a base manufactured from a standard plate or blank of a certified antiallergenic plastic. In the front part of the base, on the buccal side and the lingual side, are punched holes, through which are inwardly inserted two standard current-conducting wires having preformed connectors. The current-conducting wires are glued to the base on the inside in such a way that the bundle of protruding wires is not insulated, and the punched hole is closed and hermetically sealed. Glued into recesses formed in the base are pads made of porous viscose, which can be used as reusable pads for electrophoresis.

Description

CAPA-ELECTRODE FOR PROCEDURES IN THE ORAL CAVITY

FIELD OF TECHNOLOGY

The claimed utility model relates to the field of medicine, namely to orthodontics, and can be used to accelerate the movement of teeth together with the alveolar process on the upper or lower jaws, individually or together, by means of a device.

BACKGROUND OF THE INVENTION

The section of dentistry-orthodontics, which is an independent discipline that seeks to create a combined perfection of both function and harmony in the construction of human dentitions, is engaged in correcting malocclusion and uneven dentition.

After the end of active growth of bone tissue at the age of 14-16 years, the mineral saturation of the bone matrix of the jaws increases in a person and, as a result, orthodontic treatment of adults becomes much more difficult. Treatment terms reach from 1 to 3 or more years, which negatively affects the decision to conduct orthodontic rehabilitation.

In addition to the duration of treatment, there are a number of negative factors, such as discomfort and pain from the action of orthodontic appliances, restrictions on social communication, psycho-emotional trauma.

The prior art methods are known to reduce the time of orthodontic treatment - these are surgical and physical pharmacological methods based on the action of physical factors and pharmacological preparations that can cause changes in the bone matrix that affect the rate of resorption and opposition processes.

The degree of effectiveness of surgical operations is quite high and has been confirmed in practice by numerous cases, but with the evidence base of conservative methods, things are different. According to the authors of these methods, the acceleration of orthodontic treatment can be 50-100%, but these data are not confirmed by the practice of orthodontists who used the proposed methods. They could not repeat the declared effectiveness at home, about which there are numerous articles in the specialized literature.

Surgical methods are used in daily medical practice very rarely, due to patients' fear of pain and possible complications.

There is a known method for forced displacement of a bone matrix block (see patent RU 2705621 dated November 11, 2019), which has an efficiency superior to all known world analogues and has no drawbacks, unlike surgical techniques. The described method is based on the vital reversible intravital hypomineralization of the alveolar processes of the jaws, which is necessary to facilitate and accelerate the orthodontic treatment of malocclusion and dentition irregularities. This state of the bone matrix is achieved by carrying out physiotherapeutic procedures of electrophoresis with a 10% solution of ethylenediaminetetraacetate (EDTA), which must be carried out in the amount of 14 procedures per course of treatment, and the EDTA preparation is introduced in a certain way into the zones described in the patent. for electrophoresis. electrodes are used, made by using lead plates 1-2 mm thick with conductive conductors soldered in the middle from insulated copper wire up to 30-40 cm long.

The disadvantages of this type of electrodes include the following:

1. Lead plates oxidize during repeated use and do not allow a uniform distribution of the electric field over the electrode surface, which is very important in procedures where localization is of great importance.

2. The electrodes used in the above patent are made of plastic and are rather bulky and inconvenient to use. In addition, they occupy a large space in the oral cavity and cause a negative reaction in patients.

3. Due to the characteristics of the material, these electrodes are poorly fixed in the oral cavity, and patients during long procedures, which last up to 30 minutes, get tired of holding them in the correct position.

DISCLOSURE OF UTILITY MODEL

The objective of the proposed utility model is to create a cap-electrode that makes it possible to eliminate the above disadvantages of the electrodes used in the patent RU 2705621.

The technical result of the proposed utility model is to increase the convenience of the electrophoresis procedure by creating a modified cap-electrode design that provides a tighter fixation to the oral cavity and uniform distribution of electric potential over the electrode surface.

To achieve the set task and the specified technical result, it is proposed to create an improved model of a cap-electrode for carrying out procedures in the oral cavity, namely electrophoresis procedures, which is a base made from a standard blank plate made of certified anti-allergic plastic. Perforations are made in the front part of the base from the vestibular and lingual sides, through which two standard conductors with ready-made connectors are passed inside. Conductors are glued to the base from the inside in such a way that the bundle of outgoing wires remains without insulation, and the perforation is closed and sealed. In special niches of the base, according to predetermined boundaries, reusable physiotherapy pads made of porous viscose are installed and fixed, designed to hold the active substance during the electrophoresis procedure.

The advantage of the claimed cap-electrode is:

1. The proposed design does not contain lead electrodes, which excludes the entry of parasitic lead ions into the body, and the entire electrical potential is evenly distributed over the surface of the viscose pad and injected exactly into the intended area.

2. The combination of individual electrodes with the zero aligner provides secure fixation and convenient use during the procedure.

3. The modern and aesthetic appearance of the device does not cause negative emotions in patients, and the possibility of accurately fixing them during the time of the procedure increases its effectiveness and does not cause complaints of fatigue during the procedures.

4. The material of the electrodes is easily washed under running water, and after removing excess moisture with paper towels, the electrodes are stored in a case in a dark, cool place until the next use.

BRIEF DESCRIPTION OF THE DRAWINGS

The design of the cap-electrode is illustrated in figure 1.

IMPLEMENTATION OF UTILITY MODEL

In this section of the description, the most preferred embodiment of the utility model will be given, which, however, does not limit other possible embodiments explicitly following from the application materials and understandable to a specialist.

Patent RU 2705621 dated 11/11/2019 describes a method for facilitating and accelerating orthodontic treatment of malocclusion and dentition irregularities, which is achieved by performing physiotherapeutic electrophoresis procedures with a 10% EDTA solution. These procedures must be carried out in the amount of 14 times per course of treatment, and the EDTA preparation is introduced in a certain way into the specified zones.

To carry out the precise introduction of the drug into certain zones, a cap-electrode described in the claimed utility model is proposed, which allows you to quite simply carry out procedures not only for trained medical staff in the clinic, but also for the patient himself at home.

Capu electrode is created as follows: 1. At least one two-layer impression is taken from each jaw with a silicone material intended for taking refined non-shrinking impressions in dentistry.

2. At least one model of each patient's jaw is cast from supergypsum using the cast of the patient's jaw obtained in the previous step, or the casts are scanned and 3D virtual models are obtained, or virtual models are obtained directly by intraoral scanning.

3. Further, in one of the special programs (for example, Maestro ZD), designed for virtual remodeling of the dentition, a new construction of the dentition is prepared and coordinated with the attending physician and the patient.

4. After the approval of the virtual treatment plan, a model of the required configuration is installed on the model, scanned again and a virtual model is obtained.

5. Next, the virtual models are transferred to the 3D printer and the working models are printed.

6. After technical processing and preparation of models, after printing, they are sent to a vacuum former and the bases of the cap-electrode are made from a standard blank plate.

7. After making the base in a vacuum former, it is cut along the intended boundaries, ground and polished.

8. Then, connectors on the buccal and lingual sides in the center of the mouthguard and reusable electrode pads made of porous medical viscose, designed specifically for electrophoresis, are glued into the prepared base of the cap-electrode with any neutral waterproof hypoallergenic glue.

The procedure of electrophoresis using the obtained cap-electrode is carried out as follows. Ready cap-electrode installed on the patient's dentition, having previously moistened its electrode pads. On the one hand, the pad is moistened with the active substance intended for administration, the second side is moistened with distilled water with the addition of saline 1:10, for better conductivity. The procedure is carried out according to clinical recommendations.
