Description

The claimed utility model relates to medical equipment and can be used to measure the depth of periodontal pocket in the diagnosis and treatment of periodontal diseases in dentistry.

A periodontal pocket is formed due to a violation of the integrity of the tooth-gingival joint under the influence of submersible epithelial growth, destruction of the ligamentous apparatus, alveolar bone and cement of the root of the tooth. The condition of periodontal pockets and the condition of periodontal tissues both from the inside of the pocket and outside determines the clinical picture of the disease, the possibility of predicting it, and the choice of treatment methodology.

To examine the periodontal pocket, measure its depth, detect exudate and ulceration, and also treat, a dental probe is usually used, which in general is a straight or curved shaft with a handle on one end and a working tip on the other [see encyclopedic Dictionary

medical terms. Ch. ed. V.I. Pokrovsky. M. Medicine. 2001, 314].

In each case, the nature of the research or treatment being carried out determines the form of the probe, the use of the internal cavity, connection to the sensor system and the execution of the tip.

Known dental probe, which contains a rod, a handle and a transparent part, inserted into the periodontal pocket. A longitudinal channel is made in the probe, into which a thread is inserted, shifted forward and backward. The thread is moved until it is visible in the region of the gingival margin [US Patent US 4,708,647, A 61 C 3/00. published on 10.24.87], The disadvantage of this tool is the inconvenience of its use for measuring pocket depth, since a sufficiently thick tip is inserted into the periodontal pocket, which does not allow reproducingly fixing the bottom of the pocket and determining its depth.

Closest to the proposed model is a dental probe for measuring the depth of the periodontal pocket in the form of a rod with a handle and a curved graduated tip [US Patent US 5423677A, A 61 C 19/04 published 06/13/95].

A disadvantage of the known probe is the impossibility, with the simplicity of measuring the depth of the periodontal pocket, to accurately and reproducibly determine the outer part of the gums, corresponding to a specific or full depth of the periodontal pocket.

The technical result of the claimed device is to increase the accuracy of determining the depth of the periodontal pocket with ease of measurement and at the same time providing the ability to accurately and reproducibly determine the outer part of the gums corresponding to a certain depth of the periodontal pocket

The need to determine the state of the outer surface of the gingival tissue at the level of a specific specific depth of the investigated pocket is relevant. By comparing the degree of damage to the outer and inner surface of the gingival tissue at the same depth of the periodontal pocket, they are able to more accurately diagnose and predict the course of the disease, especially when using these studies in dynamics. By fixing the necessary depth of the pocket, it is possible to precisely establish the external line of excision of the gum during its surgical removal. The claimed utility model also helps to determine the necessary area of influence of certain drugs or physiotherapeutic procedures on the outer surface of the gums of the periodontal pocket.

The technical result of the claimed device is achieved by the fact that in a dental probe for measuring the depth of a periodontal pocket containing a rod connected at one end to a handle and at the other end with a functional tip, a distinctive feature is that the rod is straight or part of it is made the shape of a sickle, or bent at an angle, and the free end of the functional tip is made in the form of a two-pronged fork, the teeth are located at an acute angle to each other, the distance between the teeth is at a distance of At a distance from the free end equal to the maximum depth of the periodontal pocket, not less than the thickness of the gingival wall of the periodontal pocket is selected and a calibration scale is made on at least one of the teeth to determine the numerical value of the depth of the periodontal pocket. The functional tip and / or handle can be made integrally with the rod or detachably connected to the rod, for example, using a collet or threaded mechanism.

This calibration scale along with risks can contain numerical values of depth, for example, in millimeters, and can be performed with sections of different colors, which will also determine numerical values of depth, since each color will correspond to a certain value in millimeters.

The teeth of the functional tip have the same length. Optimally, the teeth have a length of 20 mm from the free end, at a distance of 12-14 mm from the free end, they can be 4-10 mm apart. The functional tip and / or handle can be made integral with the rod, and can be connected using a collet or threaded device. The tip and shaft are usually made of material (medical stainless steel) suitable for reuse after sterilization. An exception is single-use probes.

The figure 1 schematically shows a General view of the dental probe, where 1 is the shaft, 2 is the handle, 3 is the two-pronged functional tip, 4 is the collet clamp securing the functional tip.

As already noted, the functional tip (3) can be made as one with the rod (1), and can be fixed to the end of the rod (1) (opposite the handle) (2) using fixation means. The predominant type of fastening is in the form of a collet clamp (4), which is made in the form of a hollow removable threaded part with through-cuts along the axis of the shaft (1) to form petals and has means for crimping the petals around the perimeter of the shaft (1), made in the form of a hollow threaded cap installed with the possibility of movement along mating threads. However, a threaded fastener can be used, for which a corresponding thread is cut at the end of the shaft (1) and at the functional tip (3).

One of the teeth of the functional tip (3) of the dental probe is inserted into the periodontal pocket to the required depth or to the full depth of the pocket. Moreover, since both teeth have the same length, with high accuracy and reproducibility, the area of the outer part of the gum is determined, which corresponds to the depth of the pocket under study at the level of the end of the second tooth. As a result, this area can be subjected to local drug and surgical effects. According to the scale available on the teeth (or on one of the teeth), the numerical value of the depth of the periodontal pocket can be determined.

The probe works as follows: after introducing one tooth of the tip (3) into the periodontal pocket to its full depth, the depth of the periodontal pocket is determined by the corresponding mark on the scale. In this case, another tooth with high accuracy shows the outer portion of the gums, corresponding to the full depth of the pocket. You can also determine the condition of the outside of the gums at any desired depth of the periodontal pocket. The data obtained are highly reproducible and can be used for a more accurate diagnosis and the ability to predict the course of the disease, especially when using research data in dynamics. By fixing the necessary depth of the pocket, it is possible to precisely establish the external line of excision of the gum during its surgical removal. The claimed invention also helps to determine the necessary area of impact of certain drugs or physiotherapeutic procedures on a specific area of the outer surface of the gums of the periodontal pocket.
