Description

The utility model relates to medicine, namely to orthodontics and maxillofacial surgery, is intended to expand the upper jaw, normalize the dentition in children with unilateral cleft of the upper lip, palate and alveolar bone.

This technique relates to medicine, namely to orthodontics and maxillofacial surgery. It can be used in patients with unilateral cleft lip and palate. There are several ways to expand the upper dentition.

T.F. Kosyreva 03/09/2000 - patent No. 2189196 - was proposed an orthodontic device to normalize the shape and size of the dentition. The apparatus consists of a mouthguard with rings for abutment teeth with working bushings. A power arc with shape memory is installed in the working bushings. The free ends of the power arc are placed with the possibility of interaction with the support sleeves on the tooth rings. Working bushings have slots for installing the power arc, made with a diameter of 0.45-0.5 mm and a length corresponding to the size of the correct dentition. Kappa is made in the form of three moving parts interconnected by a power arc. Working bushings are fixed on the oral surfaces of the moving parts. Working and support bushings are made of metal and plastic. The result is improved interaction of the working parts with the dentition of the patient. The result is an improved interaction of the working parts with the patient’s dentition, the possibility of individual adjustment of the device and ease of installation in the oral cavity.

In the USA, Arndt, Wendell W., Berendt 07/02/1991 - patent No. 5167499 proposed an orthodontic device for palatine expansion. It consists of an orthodontic arch of the M-shaped configuration, which has a memory and retains its shape. The central segment of the M-shaped arc consists of nickel-titanium and falls on the projection of the anterior tooth group and provides expansion in the premolar region. The ends of the stainless steel arc or other biocompatible material are inserted into the palatine tubes located on the molars. The device provides a fan extension of the dentition in the area of premolars and molars, as well as rotation and introduction of molars of the upper jaw.

The disadvantages of this method in the treatment of children with unilateral cleft palate and alveolar bone are:

- The inability to unilateral correction of the dentition.

- Inability to control the degree of activation.

- The inability to move the segment by a given amount.

In most cases, treatment of children with a diagnosis of “one-sided cleft lip, palate and alveolar ridge” is carried out using removable plate devices with dilating, segmental, three-dimensional or fan screws. This disease forms the dentition in the form of a large and small segment, separated by a cleft. Moreover, the small segment is often located palatine. When using removable plate devices, children of preschool and primary school age face a hygiene problem when they are worn and with food. Particular difficulties are experienced by children who, for several reasons, did not undergo the surgical stages of treatment and have a message with the nasal cavity. A child who is in a kindergarten after eating often often cannot independently properly process the “plate” and reinstall it in the oral cavity. Orthodontic treatment of children should be performed within 24 hours a day, as in children with this diagnosis, in the absence of orthodontic treatment, a quick relapse is possible even for a short time. Failure to wear the device during the day leads to an increase in treatment time or even the impossibility of orthodontic treatment aimed at preparing for surgical correction of the defect. When using the utility model, cooperation with the patient is not required, since the device is non-removable, satisfactory hygiene is achieved, since the device does not cover the entire sky, the device can be activated to a strictly desired size - this is achieved by special stoppers.

The utility model is illustrated in the drawing, where

1. - a basic ring

2. - the central guide beam

3. - palatal clasp

4. - lateral guides of the palatal clasp

5. - spring

6. - sleeve.

Take a mold from the upper jaw. A plaster cast is cast. On the model, rings for supporting teeth are selected. A palatal clasp is made with two guides passing along the edge of the alveolar ridge from two sides, and it is fitted into the tubes of the support rings. In the center of the palatal clasp, the guide beam is soldered so that it reaches the other end of the alveolar process, and a spring with shape memory is installed. To the guide of the palatal clasp, passing along the movable segment, solder the sleeve with a diameter exceeding the diameter of the guide of the central beam at the required angle. Install the central guide in the sleeve.

The method allows to simultaneously expand the upper dentition due to the activation of the elements of the palatal arch and to produce vestibular deflection of the deformed segment due to the frame fixed structure for the upper dentition and spring with shape memory.

The apparatus is fixed, using glass ionomer cement, on the supporting rings of the molars, which are interconnected by a palatal arch, passing along the sky and free ends along the alveolar processes on both sides. A central guide beam is soldered to the center of the palatal arch, on which a spring with shape memory is installed. Activate the spring using clamping stops of the desired diameter. When activated, the spring presses on the sleeve in which the central guide is installed. Thus, there is pressure on the segment of the alveolar process and its movement occurs. The patient is advised not to eat for 2 hours. A second visit is prescribed after a month and the spring is activated again.

The technical result of the utility model is achieved due to the fact that the effectiveness of orthodontic treatment is increased in connection with the continuous wearing of the apparatus, and oral hygiene is improved.

A study was carried out using a utility model of the apparatus in three patients aged 4 to 6 years, and a positive dynamic result was obtained.

Claims (1)

An orthodontic device for normalizing the dentition, consisting of a fixed frame frame designed to be fixed to supporting molars using rings connected by the palatal arch, characterized in that lateral guides are attached to the palatal arch, on the sides of the palatal arch, at the center, soldered the central guide beam with a spring installed on it with shape memory, while the beam is installed in a sleeve that is connected to the side guide of the palatal arch made with the possibility of passage along the moved segment of the alveolar process.
