RU54306U1 - DEVICE FOR TREATMENT OF RETAINED TEETH IN CASES WHEN THERE IS NO PLACE IN THE DENTAL RANGE - Google Patents

Abstract

The device relates to medical devices, in particular to devices used in surgical interventions in the maxillofacial region and can be used in the treatment of dentofacial anomalies associated with retention of teeth and a lack of space in the dental arch for the latter, the elimination of which is associated with the movement of the retained tooth in the vestibule -oral, mesio-distal or in vertical directions. The objective of the utility model is to restore the integrity of the dental arch. The task is carried out due to the fact that the arc is made closed around the perimeter in the form of a tire consisting of medial and distal fragments connected by an individually made orthodontic screw, mushroom-shaped processes for fixing rubber rods are made on its surface. The proposed device serves to restore the integrity of the dental arch, by moving and extending the retained teeth in the thickness of the jaw bone, as well as to expand the dentition with a lack of space for the retained tooth and establish the latter in the dentition along the occlusal surface, has the following advantages: 1. technical simplicity manufacturing 2. Cheapness 3. Compactness 4. does not require enamel acid etching 5. when it is used, restrictions are not imposed when taking solid, hot, cold food.

Description

The device relates to medical devices, in particular to devices used in surgical interventions in the maxillofacial region and can be used in the treatment of dentofacial anomalies associated with retention of teeth, the elimination of which is associated with the movement of the retained tooth in the vestibulo-oral, mesi-distal or vertical directions, with a lack of space in the dentition.

It is known to use the Bracket system (V.A. Tugarin, b L.S. Persin, Modern fixed orthodontic technique Edgewise, M. 1996) to correct deviations in the vestibulo-oral and vertical directions. The system is effective, but has a number of disadvantages: expensive, when it is used, restrictions are imposed when taking solid, cold, hot food and the main disadvantage is that it requires caries prevention, since brackets are preceded by acid etching.

The closest to the proposed device is the Angle Apparatus, which is a complex structure and serves to rotate teeth around an axis, lingual inclination of teeth, expand and narrow the dental arch, and an elastic stainless steel orthodontic arch is used as a supporting part, at the ends of which there are tetrahedral nuts ending with a cylinder, orthodontic crowns or kappa (V.N. Kopeikin, L.M. Demner, Dental prosthetics. M. 1998, p. 313). The set of the apparatus includes two tubes into which the arc is tightly inserted, movable standard hooks and a ligature wire.

The disadvantage of this apparatus is a large number of elements, massiveness, technical complexity of manufacture.

The objective of the utility model is to restore the integrity of the dental arch.

The task is carried out due to the fact that the arc is closed around the perimeter in the form of a tire and consists of medial and distal fragments connected by an individually made orthodontic screw; mushroom-shaped processes for fixing rubber rods are made on its surface.

The device is an individually made tire (1) consisting of a medial (2) and distal (3) fragments on which the mushroom-shaped processes (4) are located, the bases with the mushroom-shaped process (5) and the individually made orthodontic screw (6); The device works as follows:

After drawing up a preliminary treatment plan for the patient, casts from the upper and lower jaw are taken. Models are cast and reconstructed, that is, a calculation is made and the possibility of establishing a retained tooth in the dentition is determined. A refractory model is made on which a tire (1) is composed of the medial (2) and distal (3) fragments on which the mushroom processes (4) are located, an individually made orthodontic screw (6), and the base with a mushroom process (5) on symmetric to the retined tooth. Then cast the tire (1), fragments (2, 3) and the base with the mushroom-shaped process (5) from a cobalt-chrome alloy. The next step is the manufacture of an individual orthodontic screw. Two standard orthodontic screws are taken, screw rods (7) are unscrewed from them and rings with an internal thread (8) are cut off. The rings are soldered to the medial and distal fragments of the tire. Next, the medial and distal fragments are connected by two screw rods. Perform an operation to expose the crown

the retained tooth and fixation of the base with the mushroom process (5) to the latter. Then, the medial and distal fragments of the tire with mushroom processes and orthodontic screws are fixed in the oral cavity and rubber traction is applied, the pressure of which corresponds to the direction of movement of the retained tooth, the orthodontic screw is untwisted in parallel, expanding the dental arch, creating a place for the retained tooth in it.

The proposed device serves to restore the integrity of the dental arch by moving and extending the retained teeth in the thickness of the jaw bone and establish the latter in the dentition along the occlusal surface, as well as to expand the dentition with a lack of space for the retained teeth, has the following advantages:

1. technical ease of manufacture

2. low cost

3. sufficient compactness

4. does not require acid etching

5. when using it, there are no restrictions on the intake of solid, hot, cold food.
