Description

The utility model relates to the field of medicine, namely to dental measuring instruments that can be used to determine the density of proximal contacts between teeth.

A dental measuring instrument for determining the density of proximal contacts is known from the prior art, comprising a holder and a movable part with a clamping element in the form of a dental matrix installed in the proximal contact gap between the patient’s teeth (see the article “Factors Affecting Proximal Dental Contact Strength” Eur J Oral Sci 2000; 108: 368 ± 377. # Eur J Oral Sci, 2000). Contact density in the known device is recorded when the matrix moves relative to the tooth by means of strain gauges fixed in the interdental space. The main disadvantages of such a tool are the high cost and fragility of the design, as well as the inability to obtain a quick measurement result.

The closest in technical essence to the proposed device is a dental measuring instrument comprising a holder with a micrometer and a movable part with a clamping element mounted using guides on the holder with the possibility of controlled linear movement relative to it by means of a micrometer (see patent RU2223063, class A61C 19 / 04, publ. 02/10/2004). The main disadvantage of the known device is the inability to use it to determine the density of proximal contacts.

The technical problem is the elimination of the noted drawback. The technical result consists in creating a simple and convenient measuring device that provides the ability to quickly and accurately obtain objective data on the density of proximal contacts between the patient’s teeth. The problem is solved, and the technical result is ensured by the fact that in the dental measuring instrument for determining the density of proximal contacts, comprising a holder with a micrometer and a movable part with a clamping element mounted using guides on the holder with the possibility of controlled linear movement relative to it by means of a micrometer, the clamping element is placed with the possibility of installing a proximal contact between the patient’s teeth in the gap, and the movable part in which it is fixed attached to the holder by an elastic element, the tension of which is regulated by a micrometer. The clamping element is preferably made in the form of a dental matrix with a bend at the end, and the elastic element in the form of an orthodontic gum.

Figure 1 presents a General view of the proposed dental measuring instrument;

figure 2 is a side view;

figure 2 is a top view;

figure 3 is a bottom view.

The proposed dental measuring tool for determining the density of proximal contacts contains the following basic elements:

micrometer 1;

elastic element 2 in the form of an orthodontic gum;

holder 3;

movable intraoral part 4;

clamping element 5 in the form of a dental matrix;

fasteners 6, fixing the specified matrix;

guides in the form of frames 7;

movable emphasis 8;

fixed emphasis 9;

guide metal plate 10.

The fixed part of the tool is a holder 3, in which a micrometer 1 is installed. The movable part 2 is mounted on the holder 3 by means of guides in the form of frames 7 and a metal plate 10. The frames 7 center the part 4 relative to the holder 3, and the plate 10 allows controlled linear movement relative to it by means of a micrometer 1. The plate 10 is equipped with a movable stop 8, and the micrometer has a fixed stop 9, between which the elastic element 2 is tensioned in the form of an orthodontic gum. In the movable part 4, a clamping element 5 is fixed in the form of a tape dental matrix, which is placed with the possibility of installing a proximal contact between the patient’s teeth in the slot. On one side of the matrix, the doctor creates a bend in order to obtain a more tight fixation of the matrix in the interdental space, and on the other a hole is made to fix the device with fasteners 6. Thus, the tension of the element 2 and, accordingly, the pulling force of the tape matrix of the element 5 is regulated by a micrometer one.

Dental measuring device is made of metal and polymeric materials. The movable part 4, the fasteners 6, as well as the guide frames 7 should only be made of stainless steel, due to the need for sterilization before use.

The proposed tool works as follows.

The clamping element 5 in the form of a dental tape matrix is fixed in the gingival embrasure, after which the other end of the element 5 is fixed with fasteners 6 in the movable part 4 of the proposed tool. Then, the doctor, by unscrewing the handle of the micrometer 1 counterclockwise, creates the tension of the elastic element 2 in the form of an orthodontic gum located in the extraoral part of the instrument. The created force is transmitted to the clamping element 5, fixed between the teeth. As the micrometer 1 is unscrewed, the force pushing out the element 5 begins to prevail over the forces holding it between the teeth, which leads to pulling out the element 5 from the interdental gap. After that, the doctor fixes the distance by which the micrometer 1 was unscrewed: the greater the specified distance, the greater the density of the proximal contact between the teeth.

Thus, the proposed dental measuring instrument consists of simple and accessible elements, and at the same time it allows you to easily, quickly and reliably measure the density of proximal contacts between the teeth for the correct restoration of the contact point and the possibility of accurately predicting the treatment of caries of class 2 according to Black.
