RU2309702C1 - Method and forceps for removing dental calculi - Google Patents

Abstract

FIELD: medicine.

SUBSTANCE: method involves applying forceps. Distance between clearer blade and lower branch support surface is set and the support surface is placed on the dental chewing surface. The clearer blade is brought close to the lateral tooth surface under calculus base deviating ginigiva aside and lightly pressing blade edge to the tooth. The branches are pressed together and calculus is removed. Tooth surface is processed all around in rotating the clearer blade about its axis. The forceps has lower branch connected to the upper one by means of hinge. The clearer blade is fixed in the upper branch passing into hole in lower branch plate thrusting against tooth. The branches are tubular, the clearer blade and its socket in the upper branch have curl or thread on the end opposite with respect to the blade so that the clearer blade is rotatable about its axis and no longitudinal spontaneous displacement is allowed. The clearer blade is fixed with screw movable in the upper tubular branch via internal thread to clamp the clearer blade in curl or thread zone. The hinge is designed as flexible member and the clearer blade is placed in perpendicular to the clearer blade axis.

EFFECT: improved mechanical conditions in pressing clearer blade against lateral tooth surface.

Description

1. The purpose of the invention.

Method and forceps for calculus removal are designed to reduce the risk of damage to teeth and oral tissues when calculus is removed using a gentle instrument of original design.

The scope of the invention.

The invention is intended for use in medicine, including veterinary practice.

2. The prior art.

In practice, various tools are widely used to remove tartar and clean the tooth surface with unidirectional force by the doctor, which often leads to a weakening of the connection between the tooth root and the jaw and damage to the tissues of the mouth.

Currently used method and tools for it are the forced use of means of the "Inquisition" and is a very distant prototype of the invention.

The closest prototype of the proposed method and tool can serve as forceps according to patent SU 175614 A, 12/06/1965.

The disadvantage of the prototype is that the scraper, working as a scraper, forms an acute angle with the vector of its movement when removing tartar and produces a smoothing effect, which requires an increase in the pressing force of the scraper blade against the tooth when cleaning, and therefore leads to a decrease in patient comfort, fatigue of the doctor and damage to the tissues of the mouth when the forceps slide off, in addition, structurally complex and bulky, especially their part, placed in the oral cavity.

3. The invention.

It consists in the exclusion of the application of a force to the tooth directed to the lateral surface of the tooth, loosening it and leading to the breakdown of the scraper, and therefore to damage to the oral cavity, reducing the doctor’s fatigue and nervous tension; increasing patient comfort during an unpleasant procedure, quality of cleaning the tooth surface, ease of handling of the device and quality of sterilization, simplifying the design of the device with reducing the number of parts and weight; reducing the size of the part of the forceps placed in the oral cavity, especially due to the removal of the bulky parts of the scraper attachment, and, consequently, the improvement of visibility; as well as the possibility of making forceps in any workshop.

4. Description of the invention.

The list of figures in the drawing:

figure 1 - diagram of the forceps to remove tartar;

figure 2 is a section at the place of attachment of the scraper.

4.1. The proposed method for removing tartar is that it uses forceps according to the design of FIG. 1, in which, like the analogue, the force F1 (see FIG. 1) is applied to the stone on the tooth with simultaneous compensation by its force F2, but not requiring increased pressure on the lateral surface of the tooth.

4.2. The tongs, see Fig. 1, consist of a lower jaw 1, connected as a hinge, by a flexible element 2 with an upper jaw 3, in which a screw 4 is mounted with the possibility of rotation around the axis of the scraper 5 with a blade perpendicular to its axis, and the scraper (one of the kit with a different shape of the cutting edges) passes through the window of the jaw plate 1 resting on the tooth, and to prevent slipping, the scraper and its nest are equipped with knurling or thread so that the scraper can rotate around its axis.

4.3. The principles of the method and operation of the tongs.

The forceps are taken in any hand, set the distance between the scraper blade and the lower supporting surface of the jaw plate 1 (Fig. 1), inserted into the oral cavity, impose the supporting surface on the chewing surface of the tooth, bring the scraper blade 5 under the base of the stone and move the gum, slightly pressing the edge of the blade to the tooth is compressed by branches 1 and 3 and, having applied the forces F1 and F2, they remove the stone, and by rotating the scraper around its axis, the doctor treats the tooth surface from all sides.

In addition, forceps, as a private method of use, can be used to remove tools stuck in the channels of the teeth, such as, for example, boron. In these cases, the scraper 5 is removed, and the stuck tool is passed through the window of the jaw plate 1 and, having fixed it with the clamp 4, is removed.

The difference of the proposed design from the analogue.

The jaws are made of tubular semi-finished product, which simplifies the manufacturing technology,

fastening of the scraper is carried out with a screw 4, which is moved in the upper tubular jaw 3 along the internal thread M1 (Fig. 2), obtained by casing the pipe with subsequent cutting, and clamping the scraper in the knurled area (thread) M2 on the opposite end of the blade, which prevents spontaneous longitudinal moving the scraper,

the blade of the scraper 5 is perpendicular to its axis, which ensures high-quality cleaning of teeth from stones;

a flexible element 2 in the form of a plate was used, articulating, like a hinge, jaws 1 and 3, which allows them to be brought together as close as possible to reduce the size of the part of the forceps placed in the oral cavity.

The screw 4 for attaching the scraper is located in the cavity of the upper jaw 3, which also reduced the size of the part of the forceps placed in the oral cavity.

Claims (3)

1. A method for removing tartar using forceps, characterized in that the forceps according to claim 2 are used, wherein the distance between the scraper blade and the abutment surface of the lower jaw is established, the abutment surface is placed on the chewing surface of the tooth, the scraper blade is brought to the side of the tooth under the base of the stone, pushing back the gum, gently press the edge of the blade to the tooth, compress the branches and remove the stone, and turning the scraper around its axis treat the surface of the tooth from all sides. 2. Tartar extraction forceps containing a lower jaw connected by a hinge to the upper jaw, in which a scraper is fixed that extends into the hole of the lower jaw plate resting on the tooth, characterized in that the jaws are tubular, the scraper and its socket in the upper the jaws are equipped with knurling or thread on the end opposite the blade with the possibility of turning the scraper around its axis and preventing spontaneous longitudinal movement of the scraper, while the scraper is fixed with a screw moving in the upper tubular jaw of the internal thread and clamping in the rolling scraper or thread hinge is designed as a flexible member, and the scraper blade is arranged perpendicular to the axis of the scraper. 3. The forceps according to claim 2, characterized in that they are equipped with a set of scrapers with various forms of cutting edges, including those that allow to clean the interdental region.
