Description

Technical field

The utility model relates to a device for recording the position of the lower relative to the upper jaw, which consists of two intraoral registration plates, one for each jaw, which are used in dental medicine for intraoral registration of the central ratio and horizontal, anterior and lateral movements of the lower to the upper jaw.

BACKGROUND OF THE INVENTION

There are various types of devices for recording the position of the lower relative to the upper jaw - intraoral plates of different shapes and sizes, one of which has a registration screw and the other has a recording surface.

A dental method for recording the position of the patient's jaws relative to each other through two recording plates is that of Sellmann Hans. The configuration of the two plates is approximately pentagonal, if the angular field is narrowed - triangular but without it trapezoidal. There are a total of 6 retention openings on the registration plate with screws, three on the left and right-back - large with a rounded rectangular shape, medium, smaller with the same shape and a front with rounded triangular shapes, which are located approximately in the same horizontal the plain. On the other registration plate, there are a total of 8 retention openings, 4 left and right, with quadrangular shapes, which are minimally reduced in size by the rear - forward and are approximately one plane [1].

In the cited dental method, as well as in other known intraoral recording plates, there are retentive openings of different numbers, shapes and sizes, which are approximately in one plane, or horizontal, as in the cited or vertical, in other known plates, providing insufficiently stable fixation and mechanical retention to the dental rows attach the jaws.

Technical nature and advantages

The object of the utility model is to provide a device for recording the position of the lower relative to the upper jaw, which consists of two intraoral recording plates, one for each jaw, in different sizes, but of the same shape, with which the abovementioned ones are removed. problems. One plate has a recording screw and the other has a horizontal recording surface. They are designed to be universal and fixed both in the wax shafts of the templates and to the teeth of the two jaws mechanically, by retention holes, using a silicone base. One recording surface with a recording surface is composed of a body with a flat recording surface, which is extended forward into a handle ending with a nozzle. The body is laterally bent at right angles and goes into a short vertical surface to the left and right. The other registration plate with a screw is made up of a body on which laterally there are two U-shaped grooves, in the middle of which is located a registration screw, which is winding or developing into a threaded hole. Characteristic of the two intraoral recording plates is their versatility, as well as a total of twelve retention openings on the recording surface, of which six retention openings are located laterally on the horizontal recording surface, three on the left and right, which are diametrically shaped. : large, medium and small, in the back direction - forward. The other six retention openings are located on the short vertical side of the body, three on the left and right, of equally small diameter. A total of twelve retention openings are located on the body of the registration screw plate, of which six retention openings are located on the horizontal base of the two U-grooves, three left and right, in the direction of the rear - forward, with different diameters: large, medium and small. The other six retention openings are located on the outside vertical side of the two U-shaped grooves, three left and right, of equally small diameter.

The advantages of the utility model are in the configuration of the two intraoral registration plates and in the shape, size, number and arrangement of the retention openings. The various features according to the utility model result in a more stable fixing and mechanical retention of the two recording plates.

Exemplary implementation of the utility model

According to FIG. 1a, the intraoral recording plate with a recording surface may be made in several sizes, of the same shape, with a flat recording surface and a vertical retaining surface. It consists of a body 11 completely covering the chewing and vestibular surfaces of the lower molars, premolars and canine teeth. In front of the body 11 is a flat handle 12 terminating with a nozzle 15 with an opening for the front arch holder. On the body 11, on the horizontal surface, there are six retention openings 13, three left and right, in the direction from back to front, with different diameters: large, medium and small. The horizontal recording surface of the body 11 is bent laterally at right angles and passes left and right into short vertical vestibular sides, with a total of six retention openings 14, three left and right, of uniformly small diameter.

According to FIG. 1b, a side view of the intraoral recording plate with the recording surface of FIG. 1a, on each of the two short vertical vestibular sides, to the left and right, there are three equally small retention openings 14.

According to Fig. 2a, the intraoral recording plate with a screw can be made in several sizes, in the same shape. It consists of a body 21, on which are located two U-shaped grooves, one left and right, completely covering the chewing and vestibular surface of the upper molars, premolars and canine teeth. In the middle of the body 21 is a retaining screw 23, which is wound or developable in a threaded hole 22. On the two U-shaped grooves, a total of six retention holes 25, three left and right, equally small, are located sideways on the short vertical side. diameter.

Referring to FIG. 26, a top plan view of the intraoral recording plate with the screw of FIG. 2a, on the horizontal basis of the two U-shaped grooves, there are a total of six retention openings 24, three left and right, with different diameters at the back - forward: large, medium and small. In the middle of the body 21, there is a threaded hole 22 and a registration screw 23 on the registration plate with a screw.

The operation of the intraoral recording plates is as follows:

The intraoral recording plate with a recording surface (Figs. 1a and 16) can be mounted at the height of the wax shaft of the template of one toothless jaw or by means of silicone base, it can be fixed tightly on the tooth row so that the midline of the tooth the handle of the body 11, the vertical arm 12 and the nozzle 15 should be overlapped by the midline of the face, the central incisors being freely vestibular so that their cutting edges are supported in the fold of the vertical arm 12. The front arch should be mounted ana in the nozzle 15 so that relative to the recording plate with a recording surface it is possible to determine the location of the guide wires and the wax axis. The gypsum model must then be mounted in a mini maxi articulator with the help of a recording plate with a recording surface and a face arch. After hardening of the gypsum, the recording surface with the recording surface must be removed, sterilized and returned to the oral cavity. The registration plate with screw - (Figs. 2a and 26) must be mounted either in the height of the wax shaft of the other template, or by means of a silicone base, to be fixed occlusally so that

1040 Ul firmly rests on the canine teeth, premolars and first molars. The median lines of the plates and face should overlap, with the registration screw 23 being designed in the middle of the line connecting the medial contact side of the second premolars, left and right. The registration screw 23, when wound or unscrewed in the threaded hole 22, the two plates must be spaced in the oral cavity at a minimum distance allowing smooth front and side movements, contacting only the registration screw 23 of one plate with the recording surface of the body 1 1 on the other plate. Thus, on the pencil, pastel or wax coated recording plate with a recording surface, it is possible to form an arrow angle at the top of which the two jaws are located in a central relation. Finally, the two plates must be fixed intraoral to each other by means of a silicone and a plexiglass plate, with an opening for the registration screw 23. The maxillary and mandibular models, which by means of the plates are compared in a central relation, must be fixed by gypsum in articulator.
