Description

Field of technology

The utility model is applicable in medicine, and in particular in dentistry in orthodontics and dental technology.

The utility model is used for the upper jaw in mixed and permanent dentition.

BACKGROUND OF THE INVENTION

Constructions of retention devices are known in practice [1], but in them the vestibular arch is made of cobalt-chromium-nickel wire, as the front horizontal arm covers the incisors of the dentition. The vestibular arch and hooks are soldered in the area of the first molars. The transitions between the front horizontal shoulder and the lateral horizontal arms are medial to the canines. The vestibular arch reaches the first molars. To catch up with the growth of the jaw, the retention device is replaced with another one.

Disadvantages of the known retention devices are the use of scarce and expensive materials, soldering of metal elements, insufficient stability caused by partial coverage of the dentition, short service life due to the impossibility of corrections.

Technical essence of the utility model

The utility model Retention Apparatus solves the problem of using accessible materials in orthodontics, eliminating soldering to fix the elements, adjusting the growth of the jaw, improving stability after placement on the jaw.

The utility model consists of a vestibular arch comprising a frontal horizontal arm connected on both sides by two transitions to the left horizontal shoulder passing into the left occlusal shoulder and to the right horizontal shoulder passing into the right occlusal shoulder. The vestibular arch has a left retention arm and a right retention arm at both ends. The utility model includes a left one-shoulder hook with a retention arm on the left hook and a right one-arm hook with a retention arm on the right hook, as well as an inward lingual arch with a left retention arm of the lingual arch and a right retention arm of the lingual arch. both sides of the lingual arch form a left plaque part covering the left retention arm, the retention arm of the left hook and the left retention arm of the lingual arch, as well as a right plaque part covering the right retention arm, the retention arm of the right hook and the right retention arm the lingual arch.

The vestibular arch is made of chrome-nickel steel wire with a diameter of 0.9 mm, the lingual arch is made of chrome-nickel steel wire with a diameter of 1 mm, and the left one-arm hook and the right one-arm hook are made of chrome-nickel steel wire with a diameter of 0.7 mm. mm.

An advantage of the utility model is that chrome-nickel steel wire available in orthodontics is used without soldering.

Advantages are that adjustments are possible to catch up with the growth of the jaw by changing the shape of the lingual arch, as well as improving stability by changing the positions of both transitions and one-shoulder hooks, as well as expanding the boundaries of the plaque parts, compared to known constructions of retention devices.

Explanation of the attached figure

An exemplary application of the utility model is shown in the attached figure:

Figure 1 is a general view of the retention apparatus.

Example of implementation of the utility model

An exemplary embodiment of the utility model is shown in FIG. 1.

The utility model consists of a vestibular arch 1 comprising a frontal horizontal arm 2 connected on both sides by two transitions 3 to the left horizontal arm 5 passing into the left occlusal arm 7 and to the right horizontal arm 17 passing into the right occlusal arm 15. The vestibular arc 1 has at both ends a left retention arm 8 and a right retention arm 12. The utility model includes a left one-shoulder hook 6 with a retention arm of the left hook 9 and a right one-shoulder hook 16 with a retention arm of the right hook 13, as well as located in the inner part of the lingual arch 11 with the left retention arm of the lingual arch 10 and the right retention arm of the lingual arch 14, and against both sides of the lingual arch 11 are formed a left plaque part 4 enclosing the left retention arm

8, the retention arm of the left hook 9 and the left retention arm of the lingual arch 10, as well as the right plate portion 18 comprising the right retention arm 12, the retention arm of the right hook 13 and the right retention arm of the lingual arch 14.

The vestibular arch 1 is made of chrome-nickel steel wire with a diameter of 0.9 mm, the lingual arch 11 is made of chrome-nickel steel wire with a diameter of 1 mm, and the left one-shoulder hook 6 and the right one-shoulder hook 16 are made of chrome-nickel steel wire with a diameter 0.7 mm.

The vestibular arch 1 comprises the last teeth of the dentition by means of the left occlusal arm 7 and the right occlusal arm 15, which intersect the masticatory plane of the dentition. The two passages 3 of the vestibular arch 1 are located distal to the fireplaces.

The left one-shoulder hook 6 and the right one-shoulder hook 16 are placed in the interdental space of the penultimate and last teeth of the dentition and have a club-shaped shape.

The outer boundaries of the left plaque part 4 and the right plaque part 18 are next to the turbeculae of the lateral teeth of the dentition, and the inner boundaries of the left plaque part 4 and the right plaque part 18 are 6 to 7 mm above the gingival edge of the teeth of the dentition.

Through the lingual arch 11, corrections are possible to catch up with the growth of the jaw, whereby the vestibular arch 1 is expanded and the distance between the left plaque part 4 and the right plaque part 18 is changed.
