Abstract

The invention relates to medical technology and is intended for use in dentistry. The purpose of the invention is to provide removal of deposition from the side groups of teeth. The tool contains a working part 1 with a front end 2 and samples 3, a conical part 4, a cylindrical handle 5 with samples 7. Radial samples 3 form cutting edges, which are made in an arc. The working part of the tool can be hardened by electric spark, plasma and laser processing methods. 2 Il. 2 3 (L y co 00 co (Fig. 1

Description

The invention relates to a medical technique for use in therapeutic dentistry, in particular in periodontics,

The purpose of the invention is to provide removal of deposits from the side groups of teeth.

FIG. Figure 1 shows a tool for removing dental plaque, a common

placed on the first limb conical part 4 of the handle 5, and the index finger is placed on top of the riffpen part of the latter. The patient's lower jaw is fixed with the left hand and is used as a support for the right hand with the instrument.

The rectangular end 2 of the working part 1 cuts through the solid layer

view; in fig. 2 - the same, the longitudinal of the dental stone in the places of the smallest

reading

The tool contains a diamond-shaped contour-concave-spherical working part 1 with a rectangular front

thickness to reduce the strength of its fixation on the teeth. Then the working part 1 of the tool is brought under the base of the conglomerate so that

end 2 and front-side radial radial samples 3 (cutting

ny samples 3, transitional cone face) were in maximum contact with the cervical part of the tooth. After that, the hand is sharply rotated around its longitudinal axis in such a way as to provide a two-piece part 4 with two successive bends in opposite directions along the vertical, a cylindrical knurled knob 5 having

parts, for example, an ellipsoid oval tide 6, located in the same plane with the working part 1 between two knurling or before knurling, with two-sided symmetric radial samples 7.

Radial samples 3 form cutting edges that are made in an arc. The angle of the first (conditionally down) thickened conical part 4 from the longitudinal axis of the handle 5 is the angle of the second limb in the opposite direction, the resulting angle of installation of the plane

the cutting edge of the radial sample 3 in the direction from the gums to the free edge of the teeth. Splitting the main part of tartar, the front end 2 of the working part 1 removes deposits from the cervical teeth and in the interdental spaces, if necessary turning the working part 1 at an angle of up to 90 ° and using it as a scraper to finely clean the exposed surface of the tooth neck. With the removal of deposits: from the exposed roots of the teeth, especially in the area of bifurcation (split) alternately use

the working part 1 with respect to the longitudinal 35 front end 2 and the front-side axle of the handle. In this case, the radial samples 3 of the working part 1. The SRI of the rectangular end 2 is offset relative to the longitudinal axis of the handle 5, the formula formula is 5t3 mm down when the deposits from the teeth of the lower jaw are removed and up by the same amount - when working on the upper jaw . The working part of the tool can be hardened by electric spark, plasma, laser and other known methods.

The tool is applied as follows.

A tool for removing dental deposits, containing a working part, turning into a cylindrical knurled handle, characterized in that, in order to ensure the removal

45 deposits from the side groups of teeth, the working part has a concave-spherical on the plane and a rhomboid shape along the contour with a rectangular end, enclosed between the two front faces.

Holding the tool with the grip of a writing pen, place your thumb on the plane of the radial sample 7 of the oval tide 6, middle finger

placed on the first limb of the conical part 4 of the handle 5, and the index finger is placed on top of the riffen part of the latter. The patient’s lower jaw is fixed with the left hand and used as a support for the right hand with the instrument.

The rectangular end 2 of the working part 1 cuts through the solid layer
