Abstract

A tire for fixing and stabilizing teeth, having wire reinforcement, characterized in that the tire reinforcement is made integral with the photopolymer material and cavities in the teeth with an oral and / or chewing surface.

Description

The proposed utility model relates to dentistry and can be used in the treatment of periodontal disease, namely to eliminate pathological tooth mobility, restore chewing effectiveness, and remove inflammatory processes in periodontal tissues.

Diseases of periodontal tissues are the main massive lesion of the dentition. These diseases cause a significant decrease in the functional capabilities of the maxillofacial system and significantly affect the vital activity of the whole human body. Solving issues of early diagnosis, comprehensive and effective treatment, and developing preventive measures for periodontal diseases are important for maintaining the integrity of the dentition and restoring the physiological function of the entire dentition: S. Yu. Kurlyandsky, Orthopedic Dentistry, 1969: V.N. Kopeikin, Orthopedic Dentistry , 1988: T.V. Nikitina, Parodontosis, 1982, etc.).

To eliminate tooth mobility during orthopedic treatment, a number of different types of permanent fixed mines have been proposed: ring, cap, crown, beam, insert, etc. Also, various types of plastic mouth guards, interdental mining structures by V.N. Kopeikin are used to splint movable teeth in the frontal sections.

and individual splint metal tabs. So, an intradental splint for splinting teeth is known by the authors. St. USSR, H 165188, cl. AB1C7 / 32. Yina consists of support elements in the form of open U-shaped loops and support elements from a wire blank. In the teeth from the oral surface, vertical channels are made in which the supporting elements are laid. Horizontal sections of the tire are laid in transverse grooves in the teeth, and the flank support elements of the mine are installed in the canal canines. Mina has disadvantages:

-boundedness of its application (only as intradental)

-high morbidity due to the need to perform a significant number of grooves in the teeth:

-the complexity of the operation when splinting:

- insufficient aesthetics.

The insert design is also known (E.Y. Gavrilov. Orthopedic dentistry. Medicine, p. 231-232). Initiation in this case involves cutting a groove on the occlusal surface of the teeth, removing the impression and modeling on the beam wax. Then the wax is replaced with metal and the beam is fixed in the groove with cement. Sometimes a beam is used in combination with crowns, pins.

The proposed tire is often uncemented, under the influence of functional loads, the beam comes off the teeth. The tire is unaesthetic because visible in the oral cavity.

For the prototype, we adopted a method of stabilization of teeth, indirectly protecting the tire, according to the patent of the Russian Federation N 2026029, class. JV / S7 / 00.

The bus is as follows. A cut is made in the middle of the occlusal surface of the stabilized teeth, a wire beam is laid on the bottom of it. A groove is cut out on each tooth, into which brackets are inserted from material with shape memory. Surface

beam structures are coated with a composite.

The tire design is complicated in execution, its installation is highly traumatic, not always available titanium nickemide material is required, the beam made on the chewing surface creates inconvenience during chewing functions and dental care.

3 of all the above splinting structures, the disadvantages are:

a) significant preparation of hard tooth tissues:

b) in the case of the use of root pins, tooth depulpation is required;

c) tires do not meet modern aesthetic requirements:

d) not all splinting structures are able to provide strong fixation and stabilization of teeth in the vestibulooral and mesio-distal directions:

e) loose fit of Nina to natural teeth often leads to its discementation:

e) most of these splinting structures do not allow the free conduct of therapeutic measures in the oral cavity.

The aim of the proposal is to reduce the volume of processing of hard tooth tissues, increase aesthetic requirements and structural strength, eliminate the annoying effect of the tire on marginal periodontics, and exclude retention points for food retention.

The essence of the design of the tire for fixing and stabilizing teeth is the implementation of wire reinforcement along with photopolymer material and cavities in the teeth from the oral and (or) chewing side.

In figures 1-4 shows various options for the proposed tire, namely:

Figure 1 - splinting of teeth on the chewing side. The figure highlights the reinforcing wire 1, fixed in the cavities 2 by photopolymer 3. Figure 2 - splinting of the front teeth - options

blocks.

A tire for fixing and stabilizing teeth is used as follows. When identifying patients with periodontal diseases of the teeth and the rows of the patient are fully examined. They recommend treatment aimed at improving the trophism of periodontal tissues: they prescribe general strengthening therapy, reduce the influence of the exogenous factor - removal of dental deposits, replace poor-quality fillings and crowns, perform functional grinding of areas of hard tissue blocking the movements of the lower jaw. An orthopantomogram of the jaw is made for the patient to study the condition of the bone structure and areas of dental safety in order to exclude the opening of the pulp of the tooth during preparation. In some cases, when necessary, teeth are pulped. After carrying out these measures, they begin to form cavities for the mining structure.

When preparing the frontal group of teeth, cavities are placed from the lingual or palatal surface so that the distance between the cutting edge and the edge of the cavity is at least 2-3 mm. This is necessary in order to maintain a sufficiently strong layer of hard tooth tissues that can withstand the vertical load. In the lateral group of teeth, cavities are created on the chewing surface of an oval shape or in the form of a parallelepiped. The thickness of the enamel layer is 3-6 mm, the depth of the cavity should be at least 1-1.5 mm, width from 1-4 mm.

kami. The formation of cavities of hard tissues of teeth is carried out according to all the requirements relating to the formation of cavities under the tabs. Further, these cavities are interconnected by approximate grooves, 0.5-2 mm wide, moving from one tooth to the next one. Bevels (folds) must be made in the area of the enamel layer to prevent tire splitting and caries formation.

After creating the cavities of the required shape, antiseptic treatment is carried out according to a standardized technique, dried and an orthodontic wire with a diameter of 0.3-0.6 mm is laid at the bottom of the cavities and grooves. Subsequently, this wire is coated with a composite photopolymer material; the wire is an armature for the tire and is not visible in the oral cavity.

In case of complication of the course of the disease or in connection with therapeutic measures (for example, depulpation), any link of the splint design can be removed, the teeth can be treated without removing the entire structure and after the treatment, restore the tire in its original form.

Nina is a single splinting structure into which individual teeth can be included in a block. FIG. 2,3), or the entire dentition of the lower or upper jaw C of FIG. 4 ).

With all mining options, this technique can include parapulpar and anchor pins C in case the teeth are depulped). These supplements improve the fixation of the splinting structure and increase its strength.

The proposed tire for fixing and stabilizing mobile teeth in periodontal diseases with photopolymer composite materials was tested at the Department of Orthopedic Dentistry of the Kuban State Academy for 18 patients. Positive results were obtained in all prosthetized patients with this splint design.

On the obtained x-ray photographs before and after treatment, after 1 month, 3 months, stabilization of destructive processes in lean tissue is determined, inflammatory and dystrophic phenomena are reduced, pathological tooth mobility is significantly reduced.

Testing the tire showed that it is simple and convenient to manufacture, does not require significant processing of hard tooth tissues, meets high aesthetic requirements, creates a strong block from the group of teeth and from the entire dentition, limits the pathological mobility of teeth in three directions: vertical, vestibular, mesiodistic (for the lateral) and mesiolateral (for the frontal), does not irritate the periodontium, provides access to the gingival pocket, does not create retention pockets for food retention, not an obstacle exists a movement of the jaws and do not interfere with razgorrnoy .L
