Description

The utility model relates to medicine, namely to dental devices and can be used for making and modeling composite materials during restoration of cavities of any class.

There are means for applying adhesives, photopolymer and chemical filling materials with the help of applicators, ironers, dies. The use of these tools does not fully ensure sealing of the dentinal tubules, and the process of introducing filling materials into the tooth cavity is associated with various difficulties of adhesion to the instrument, pore formation, and tight marginal fit.

The appearance of solvent-free viscous adhesives, self-etching adhesives, necessitated their long-term rubbing into the surface of enamel and dentin.

A device for sealing root canals (AS USSR, N 923537, A61C 5/04, 1979), comprising a housing, a shaft, a root needle, a reservoir for filling mass, in which a spring-loaded piston with a clamp, made with a longitudinal - an axial channel, into which a root needle enters, mounted with the possibility of axial movement, while the free end of the housing is equipped with a curved fitting, the shaft consists of interconnected spring-loaded working and transition shafts, the housing is made of a material having release agent with respect to the filling mass.

Significant disadvantages of this device, the sticking of the filling mass over the entire working surface of the root needle, the surface of which represents a helix and the possibility of this mass falling outside the apical hole of the tooth, reduces the quality of the filling, and the need to remove the filling mass that has fallen on the walls of the apical hole increases the process time sealing indicates a low quality of sealing, as well as the imperfection of the device itself and the low-tech design.

The use of traditional tools for working with polymeric materials with ironers, plugger, etc., has the following disadvantages: adhesion of the filling material to the working surface of the tools, a large number of uniform movements (rubbing the material) to achieve high-quality adaptation of the material to the walls of the cavity, difficulties when working in hard-to-reach places, the inability to influence the formation of pores inside the filling material.

The well-known device for working with polymer materials Comporoller (Compoller) company Kerr (http://www.kmm.com.ua/index.php?page=shop.product_details&product_id=986&flypage=flypage.tpl&pop=0&option=com_virtuemart&Itemid=118&lang.ru) .

Comporoller is a tool for modeling composites, designed to provide control over the adaptation of composite layers and to give restorations made by the direct method to their final shape. The working parts of the Comporoller tool are roller nozzles, do not stick to the material and ensure the creation of homogeneous layers of any composite without the formation of air bubbles.

The disadvantage of this design is the inability to use in hard to reach places, the inability to work with adhesive, the absence of vibration does not remove air bubbles from the polymer material.

Known dental device (US Pat. RU No. 2112453, A61C 5/04), which relates to tools for processing the root canals of teeth, and can be used in the treatment of apices of periodontitis using low-frequency ultrasound. The device contains a removable working tool, which is inserted into the collet clamp. The collet clamp by the attachment unit is rigidly fixed on the waveguide for using the devices of the endoscopic set. The disadvantages include the well-known tool for processing root canals is not available to practitioners (therefore, only experienced lots of endodontic instruments exist), and it is very expensive.

The closest technical solution is a dental device (US Pat. KM UA, No. 950, A61C 5/04, 07/16/2001, bull. No. 6). The proposed dental device contains a removable working tool inserted in a collet clamp with a mount, and the waveguide is rigidly connected to the collet clamp. The device is equipped with at least one elastic tube mounted on a removable working tool with the ability to move along its surface.

However, this design does not exclude the ingress of filling material into the patient’s oral cavity during operation, and it has a narrowly targeted effect.

The utility model is based on the task of improving the dental device by providing it with a battery and a vibration source installed in the cavity of the body, such an improvement reduces the cost of raw materials, improves the process of dental treatment, namely this tool will fully seal the dentinal tubules, the filling material does not stick to the tool does not form pores, it allows you to provide a tight marginal fit.

The problem is solved in that in the dental device for introducing and modeling composite materials containing the housing, a removable working tool installed in the holder, an additional battery, a vibration source installed in the cavity of the housing and a switch are provided. In addition, the proposed dental device is characterized in that the housing is made of a polymeric material or stainless steel, and a vibration motor or piezoelectric transducers are used as a source of vibration.

Between the totality of the essential features of the claimed object and the achieved technical result there is a causal relationship, namely due to the inclusion, the electric current coming from the battery to the vibration source causes the oscillation of the latter. Together with the source of vibration, the body begins to oscillate, to which the tool holder is rigidly fixed. A working tool rigidly fixed in the tool holder also begins to oscillate at the same frequency as the vibration source. The vibration frequency depends on the power of the battery. The working tool fixed in the holder carries out reciprocating movements with respect to the tooth surface, which leads to better application of adhesive (filling material) and better sealing of the dentinal tubules. When working with polymer material, a vibrating tool, colliding directly with the material, causes the material to vibrate, causes the material to flow into the smallest undercuts, removes air pores from the material, and homogenizes the material.

The utility model allows to reduce raw material costs, improve the process of dental treatment, namely, this tool will provide full sealing of the dentinal tubules, the filling material does not stick to the tool, pores do not form, and a tight marginal fit is ensured.

The technical essence and principle of operation of the claimed device are explained in the drawing, on which:

figure 1 shows a General view of the proposed device with a local section.

The proposed dental device consists of a housing 6, inside of which there is a battery 2, a vibration source 1, a switch 5, a holder for a working tool 3, a working tool 4.

The above structural elements are made in this way - the device contains a hollow body, inside of which there is a battery and a vibration source, a switch, holder, a removable working tool is inserted into the holder.

The case is made of a polymeric material or stainless steel, the vibration source is a vibration motor or piezoelectric transducers.

The dental device described above is used as follows a working tool 4, is inserted into the holder 3, when the switch 5 is turned on, a current is supplied to the vibration source 1. The vibrator begins to vibrate at a given frequency, oscillations. Select the optimal mode of operation of the vibration source. The vibration is transmitted to the tool holder 3 and then to the working tool 4. The working tool distributes the filling material to the walls of the tooth cavity.

When filling with a working tool 4, the filling material is applied to the tooth cavity, which provides a stronger fit of the filling material to the walls of the tooth, this is important.

Due to this, a better adhesive layer is obtained, dentinal tubules are better sealed, as a result, postoperative sensitivity decreases. When photopolymer and chemical materials are introduced into the tooth cavity, the vibrating working part of the tool better adapts the filling material to the walls of the cavity, improves the condensation of the material, facilitates the introduction of material in hard-to-reach places, removes pores.

The simplicity and manufacturability of structural forms, controllability in manufacturing, the availability of assembly of the components of the device creates favorable conditions for the release of these parts for use.

The device is convenient for use, well tolerated by patients, has no side effects and contraindications. The tool has an ergonomic design, reduces hand fatigue. The data obtained allow us to recommend the proposed device in a wide dental practice.
