Description

The invention relates to medicine, is used in the field of dentistry for orthodontic treatment of patients with primary adentia to close a dentition defect in the frontal group of teeth.

With primary adentia, it is often necessary to carry out orthodontic treatment, at the last stage of which, after creating a place for an absent tooth, a defect in the dentition and an aesthetic defect arise, which causes anxiety in patients. In order to close the defect during the treatment with the braces, it is possible to strengthen the braces on the artificial tooth and tie it to the arch, which improves the aesthetic effect at the stage of orthodontic treatment.

The relevance is due to the high frequency of patients with primary edentulous access to orthodontic treatment for anomalies of the dentition and the high demands of patients on the aesthetic side of treatment.

Currently, during orthodontic treatment of patients with primary adentia braces, a defect in the dentition often does not close. The defect closes when switching to removable equipment due to the placement of a plastic tooth. This reduces the aesthetic effect of orthodontic treatment with fixed equipment, causing discomfort in patients.

Sometimes, to close the defect, the bracket is glued to the artificial tooth using composite materials and tied to the arch with the artificial tooth. (Profit U.R., 2006. - p. 493). However, this connection does not provide reliable fixation between the bracket and the artificial tooth, which leads to frequent spallations of artificial teeth and, accordingly, an increase in the number of visits to the patients of their orthodontist.

Closest to the device for replacing a dentition defect in the orthodontic treatment of patients with adentia using the braces is the bracket bracket proposed by Halke Gunter, Rybczynski Stefan (2006), but it is laborious to manufacture.

The objectives of the proposed technical solution are:

1) providing an aesthetic effect in orthodontic treatment;

2) ensuring stable fixation of the bracket on the artificial tooth using metal pins.

The specified technical result is achieved in that the device for replacing a dentition defect during orthodontic treatment of patients with adentia using a braces system consists of a standard metal bracket with two steel pins soldered to it and a standard plastic artificial tooth connected to the bracket with pins and quick-hardening plastics. An artificial tooth is selected according to the size of the defect and the color of their own teeth. The length of the pins depends on the size of the artificial tooth. The diameter of the pins depends on the size of the bracket substrate. A standard bracket is selected depending on the group affiliation of the tooth.

A device is proposed for replacing a dentition defect during orthodontic treatment of patients with adentia using a bracket system, which is an artificial tooth prosthesis with a bracket attached to it, where a bracket with a substrate to which two steel pins are soldered is located on the vestibular side of the artificial tooth, the pins are drawn through the entire thickness of the artificial tooth in the buccolingual direction, and their ends on the oral side are bent and laid in a suit formed on the oral surface natural tooth grooves.

In this case, the pins are soldered to the bracket at one end, and the other, free, is fixed on the oral surface of the artificial tooth, providing reliable fixation between the metal bracket and the plastic artificial tooth.

The manufactured device is installed in the dentition and tied to the arch, thereby closing the dentition defect and increasing the aesthetic effect of the orthodontic treatment of patients with primary adentia.

A device for replacing a dentition defect during orthodontic treatment of patients with adentia using a bracket system makes it possible to reliably fix a bracket to an artificial tooth. The device closes the defect in the dentition during orthodontic treatment of primary adentia by installing it in the dentition and tying it to the arch.

The claimed technical solution is illustrated by illustrations, where in FIG. 1 shows a view of a model with a dentition defect; in FIG. 2 is a view of a bracket with soldered metal pins; in FIG. 3 is a view of a bracket fixed on an artificial tooth; in FIG. 4 is a view of a model with a device installed in the dentition and tied to the arch to replace a dentition defect in the orthodontic treatment of patients with adentia using a braces system.

The inventive device for replacing a defect in the dentition during orthodontic treatment of patients with adentia using a bracket system is made as follows:

- select a standard artificial tooth depending on the defect of the dentition (Fig. 1);

- two steel pins with a diameter of 0.6-0.8 mm are soldered to the standard bracket substrate in the groove projection (depending on the thickness of the substrate);

- each of the pins is located at a distance of 1 mm from the mesial and distal edges of the bracket substrate (Fig. 2);

- the length of the pin depends on the thickness of the artificial tooth;

- an artificial tooth fit in the oral cavity;

- on the artificial tooth, the marker marks the position of the bracket and the location of the pins;

- boron corresponding to the diameter of the pins, drill channels in the buccolingual direction of the artificial tooth;

- on the oral surface of the artificial tooth from the place of exit of the channels parallel to the long axis of the tooth, two grooves are drilled;

- on the artificial tooth in the places of positioning the bracket remove the surface layer of plastic;

- an artificial tooth and bracket with soldered metal pins degrease;

- on the artificial tooth, the position of the bracket, the channels and oral grooves are treated with a monomer;

- monomer process the bracket substrate and the pins attached to it;

- pre-selected in color and mixed quick-hardening plastic is applied to the pins, channels and grooves of the artificial tooth from the oral side;

- the bracket with the soldered pins is fixed to the artificial tooth (Fig. 3);

- the ends of the pins on the oral side are bent and laid in the grooves of the artificial tooth;

- excess plastic is removed from the vestibular and oral sides;

- after hardening of the plastic, final grinding and polishing of the structure is carried out;

- the finished device is installed in the dentition and tied to an arch with steel or elastic ligature (Fig. 4).
