Abstract

Dental cuvette refers to orthopedic dentistry, and can be used to make removable dentures. The proposed dental cuvette is simple in design and easy to operate with high quality workmanship. The dental cuvette contains a collapsible case made of lower 1 and upper 2 parts with a clamping device. The clamping device consists of a clamping plate 3, clamping nuts 4 and vertical posts 5, made in the form of bolts threaded through the holes of the side brackets 6 of the collapsible housing and the clamping plate 3. The upper part 2 is made with a receiving window for gypsum 7. Along the edges of the lower 1 and upper 2 parts made recesses for the output gate 8. In the center of the pressure plate 3, the input gate 9 is made.

Description

The utility model relates to medicine, in particular to orthopedic dentistry, and can be used for the manufacture of removable dentures.

Dental cuvettes are known, comprising a collapsible housing made of lower and upper parts with a pressure plate, interconnected by vertical racks and a pressure device (see ed. Certificate of the USSR No. 992050 according to MKI A 61 C 13/16, declared January 25, 1980 city and author of the certificate of the USSR No. 1194410 according to MKI A 61 C 13/16, declared January 25, 1980)

The closest in technical essence is a dental cuvette containing a collapsible case made of lower and upper parts, a clamping device, a pressure plate and vertical racks (see ed. Certificate of the USSR No. 1194410 according to MKI A 61 C 13/16, declared 01/25/1980 g.)

Common disadvantages of the known cell is the complexity of the design and low quality of the manufactured products.

The utility model is based on the task of creating a simple and easy-to-use dental cuvette with high quality workmanship.

The problem is solved in that in a dental cuvette containing a collapsible body made of lower and upper parts, a clamping device with a clamping plate and vertical racks, according to a utility model, the lower and upper parts are made symmetrically relative to each other with equal dimensions and inclined walls, and the upper part is made with a receiving window for gypsum.

The essence of the utility model is illustrated by drawings.

Figure 1 shows the proposed cell assembly, General view;

figure 2 shows the upper part of the collapsible housing.

The dental cuvette contains a collapsible case made of lower 1 and upper 2 parts with a clamping device. The clamping device consists of a clamping plate 3, clamping nuts 4 and vertical posts 5, made in the form of bolts threaded through the holes of the side brackets 6 of the collapsible housing and the clamping plate 3. The upper part 2 is made with a receiving window for gypsum 7. Along the edges of the lower 1 and upper 2 parts made recesses for the output gate 8. In the center of the pressure plate 3, the input gate 9 is made.

The manufacture of two removable dentures using the proposed cell is as follows.

Two gypsum models of jaws with wax reproductions of prostheses are installed on the bottom of the lower part 1 of the collapsible case with frontal teeth facing towards each other, without touching the projection of the inlet gates 9 in the pressure plate 3. The lower part 1 of the cuvette is filled with liquid gypsum to the edges. Upper part 2 is installed along the vertical strut 5. Wax reproductions of the inlet sprue canals are glued to the frontal teeth for wax reproductions of the sprue ducts in the direction of the inlet sprue holes 9 of the pressure plate 3. Wax reproductions of the sprue outlets are installed in the distal parts of the wax reproduction of the upper jaw in the region of the maxillary tubercles and towards the outlet gates 8 on the lower jaw.

The upper part of the cell 2 through the receiving window for gypsum 7 is filled with liquid gypsum. A pressure plate 3 is mounted on a vertical strut 4 so that the ends of the wax reproductions of the input gate channels protrude through the input ligar holes 9 beyond its limits.

After crystallization of the gypsum, the cuvette is placed in boiling water for 5-10 minutes to boil the wax from the gypsum mold. The gypsum form of the cuvette is washed with a stream of hot water through the inlet gates 9 of the pressure plate 3, and after cooling the cuvette to room temperature it is washed with a solution of Izokol insulating varnish with water 1:20. Through the inlet gates 9, the gypsum mold is filled with basic plastic using domestic devices, for example, ShK-1 or Research Institute Impuls. The control of filling the gypsum mold is the exit of the plastic through the outlet lighter holes 8. The cuvette is put into polymerization for the duration of the plastic used in the instructions, respectively. Then, for about two hours, the cuvette is cooled at room temperature, disassembled in the reverse order of assembly, and a plaster mold is taken out, from which models with removable dentures are removed.

The proposed dental cuvette is simple in design and easy to operate with high quality workmanship. The proposed cuvette allows to improve the manufacturing technology of removable prostheses from acrylic plastics by compression or injection molding in domestic devices, for example, ShK-1 and the Research Institute "Impulse", to exclude the use of such devices as a "mechanical press" and "clasp", and also allows to manufacture simultaneously two prostheses.
