Description

FIG. 7

This invention relates to medicine, in particular to prosthetic dentistry.

The aim of the invention is to improve the accuracy of setting teeth.

FIG. 1 shows the proposed device, a general view; in fig. 2 - the same, top view.

The device contains an article torus 1 with a frame 2 and a positioning plate 3 with a spherical surface 4 connected with article one 1. In addition, the device contains a rod 5 with millimeter divisions, a clamping sleeve 6 and a guide 7 with a movable indicator 8, the lower end of the rod 5 is fixed on the plate 3, and the upper end of the rod 5 is in the clamping sleeve 6 with the ability to move in a vertical plane relative to the sleeve 6, which is placed in the frame 2 of the part number 1. Moreover, the guide 7 is located perpendicular to the frame 2 s vozm The movement is possible, and the setting plate 3 has an additional flat surface 9, an opposed spherical surface A, and side surfaces 10.

The device is used as follows.

First, the size of the production plate 3 and the radius of its spherical surface are determined. The use of staging plates 3 for constructing dental rows in complete dentures is determined by matching the width of the patient's lower jaw in the region of the lost first mol and the width of the dental row between the buccal bumps of the first mol of patients with orthognathic bite.

The model of the upper jaw with the base and the occlusal roller (not shown) is placed on the production plate so that their middle lines coincide, and the movable pointer 8 abuts against the center line marked on the occlusion roller, and glue the latter with wax to the production plate 3. Then the model is plastered to the upper frame 2, the article of the torus 1.

The fang lines are transferred to the plate 3 and continue to the lower surface, which, together with the front point of the production plate 3, define the vestibular oval of the maxilla model base and the width of the front teeth of the lower jaw prosthesis. Having removed the production plate 3, the model with the base of the lower jaw is attached to the base of the model of the upper jaw and they cast it to the lower part of the articulator.

Removed from the models bases with occlusion rollers and set

Q again the production plate 3, moving it up from the initial position by 2 mm (in this case, the thickness of the front row of the production plate) to establish the level

5 occlusal surfaces on the lower surface of the setting plate 3i A new base with a roller for setting the teeth is prepared for the model of the lower jaw. Setting teeth on. Basis

The model of the lower jaw is produced in the center of the alveolar part, so that their cutting edges and chewing knolls touch the spherical surface 4 of the production plate 3.

5 Having removed the production plate 3, a new base with a roller for setting the teeth is prepared on the upper jaw model. The setting of teeth on the basis of the upper jaw model begins with

The first molars, then the second molars, the second premolors and the first premolars, check for contacts on the working and balancing sides. After setting the lateral teeth, the front teeth are installed, also checking for the presence of contact of the teeth during various movements of the upper frame 2 and the article of the torus 1.

Claims (1)

The proposed device allows to obtain sagittal and transtrate occlusive curves of artificial dental series, similar to those with orthognathic bite, and thus, to design dental rows in prostheses as accurately as possible and to restore the chewing effectiveness of the dentofacial system. The use of a set of production plates 3 makes it possible to individualize the design of dental rows in complete dentures, and thereby, to maximally restore the chewing effectiveness of the dentofacial system. Invention Formula 5 A device for setting teeth in complete removable dentures, containing a torus with a frame and a setting plate with a spherical top5 0 five 0 This is associated with an article number, characterized in that, in order to improve the accuracy of the teeth, it is equipped with a rod with millimeter divisions, a clamping sleeve and a guide with a movable pointer, the lower end of the rod is fixed on the plate, and the upper end of the rod - in the clamping sleeve with the ability to move in the vertical plane relative to the hub placed in the frame of the articulator - torus, and the guide is located perpendicular to the frame of the articulator of the torus with the possibility of movement, and the production plate has an additional flat surface, opposite to the spherical surface, and lateral surfaces perpendicular to the flat surface.
