Description

The invention relates to medicine, namely to dentistry and is used to correct removable dentures.

A number of tools are known for correcting removable dentures, in particular, places that exert excessive pressure on the mucous membrane of the oral cavity, including a composition for correcting dentures [1], dentol (oxycine-eugenol paste) [2], silicone impression mass (application for invention No. 2014133636, 08/14/2014), carbon paper [3], denture correction paste [4], Bausch precision marker, Bio-Ink marking ink [5].

The closest technical solution selected for the prototype is the composition for the correction of dentures [6]. In the prototype, during the preparation of the composition, carboxymethyl cellulose (2.5 - 3.0 weight parts) is stirred in distilled water (25.0 - 30.0 weight parts), after which methylene blue (2.0 - 2.5 weight parts), zinc oxide are successively added to the mixture. (10.0 - 10.5 parts by weight), anestezin (0.1 - 0.2 parts by weight) and streptocide (0.5 - 0.75 parts by weight). All components are thoroughly mixed and sterilized in a water bath. A portion of the resulting mass is applied with a spatula or trowel to the area of tissues exposed to the traumatic effect of the prosthesis, the prosthesis is placed on the jaw, after which the painted parts of the basis are ground and polished.

The disadvantages of this technical solution include:

- the presence of streptocide in the composition, the use of which is contraindicated in patients over the age of 65, including patients with chronic heart failure, liver diseases and kidney impairment, patients with diabetes mellitus;

- a viscous consistency that does not allow the precise application of small amounts of a highly staining preparation, including by extruding it from a syringe. Due to this, the prototype (like other known means) does not provide accurate marking of the prosthetic bed.

The problem to which the present invention is directed is to develop a method for preparing a denture correction composition that improves the accuracy of dentures correction due to the possibility of applying small portions of a moderately viscous preparation to injured areas of the oral mucosa of a wide range of patients.

The specified technical result is achieved by the fact that the proposed method for the correction of removable prostheses, including mixing with a hot aqueous solution of sodium salt of carboxymethyl cellulose (CMC) a solution of methylene blue and a solution of chlorhexidine bigluconate, characterized in that prepare aqueous solutions of methylene blue and chlorhexidine bigluconate calculation so that in the finished product their content was 1.0 wt.% and 0.02 wt.%, respectively, the resulting solutions are mixed with a hot 8% aqueous solution of CMC , cool and place in syringes. A portion of the composition is squeezed out of the syringe with a cannula with a diameter of 1 mm to the identified areas of trauma by the prosthesis of the mucous membrane of the alveolar process. The prostheses are fixed on the jaw, after which the painted areas or the edges of the base are ground with a mill, and the edges of the prosthesis are sanded and polished.

The sodium salt of carboxymethyl cellulose in the claimed invention is used as a gelling substance, the basis of the drug. It is not fermented by microorganisms, which ensures a long shelf life of the composition. The number of CMC is selected empirically and provides the optimal consistency of the drug.

Methylene blue is used as a coloring agent, which also has antiseptic properties.

Chlorhexidine bigluconate is introduced into the composition to enhance the antiseptic properties of the drug.

The salient features of the claimed technical solution are that:

- prepare aqueous solutions of methylene blue and chlorhexidine bigluconate, so that in the finished product their content is 1.0 wt.% and 0.02 wt.%, respectively,

- the resulting solutions are mixed with a hot 8% aqueous solution of CMC, cooled and placed in syringes.

Due to the combination of distinctive features of the claimed method, a moderately viscous staining preparation with antiseptic properties is obtained, which can be used as a composition for the correction of removable dentures in orthopedic dentistry.

The inventive method is confirmed by the following examples.

Example. To obtain 100 ml of the composition, 24 ml of an aqueous solution of methylene blue and 1 ml of chlorhexidine bigluconate are prepared, so that their content in the finished product is 1.0 wt.% And 0.02 wt.%, Respectively. Each solution is combined with 75 ml of a hot 8% aqueous CMC solution. The mixture is cooled to room temperature and placed in syringes. To carry out the correction of removable prostheses (partial and complete), apply a portion of the composition with a syringe with a cannula with a diameter of 1 mm to the area of high pressure, the identified areas of trauma to the prosthesis (redness, swelling, ulceration) of the mucous membrane of the alveolar process. The prostheses are fixed on the jaw, after which the resulting pressure zones (i.e., the painted areas or the edges of the base) are sanded with a mill, and the edges of the prosthesis are sanded and polished.

The proposed composition for correction was tested at the Department of Orthopedic Dentistry, FSBEI HE Omsk State Medical University of the Ministry of Health of Russia and the Orthopedic Department of GKSP No. 1 of Omsk. It was established that the developed composition has good adhesion to the soft tissues of the prosthetic bed, does not spread, stains the mucous membrane well, leaves informative prints on the surface of the prosthesis, while the ability to squeeze the drug through the cannula of the syringe allows you to dose small amounts of the staining mixture depending on the size of the mucosal lesion area shells (naminov) and thereby avoid unnecessarily marking areas of the prosthesis in the area of which there is no traumatic effect. The developed composition is well stored in sealed vials or closed syringes, does not change the initial properties during storage. The composition is simple to use and does not require special skills for work.
