Abstract

An apparatus for determining the possibility of placing a retarded tooth in the dentition, characterized in that it consists of: a standard polymer base, support clasps and a functional shoulder located directly above the location of the defect, and an orthodontic button located on the surface of the retarded tooth and connected by means of a ligature wire to hook hooks of a functional shoulder.

Description

The utility model relates to dentistry, namely to orthodontics, and can be used to treat patients with delayed eruption of permanent teeth (retention), i.e. the tooth did not erupt within two years after the onset of normal eruption. According to the literature, retention occurs in 4-18% of patients visiting a dental clinic

Problems in the oral cavity, associated indirectly or directly with the extracted teeth (teeth that are not able to erupt properly, since they are completely or partially covered by bone or mucous tissues), at the present stage of development of dentistry occupy a considerable share of cases of referring to dentists - to orthodontists, and to specialists in related disciplines. (one)

Causes of eruption can be different, for example, the most common cause of retinated fangs is the early loss of milk teeth and the incorrect location of the tooth crown. Also, the reason may be the incorrect location of the tooth germ and supernumerary teeth (when a person has more teeth than expected). Crowding of the teeth is also possible, in connection with which the tooth simply does not have enough space in order to cut through. The most rare cause of this condition, dentists consider a violation of the activity of the endocrine glands.

Retention of individual teeth can be a cause of difficulty biting off food, infantile swallowing, pathological oral breathing, a bad habit of laying the tongue in a dentition defect. The absence of separate front teeth as a result of retention in the dentition and the abnormal position of adjacent teeth leads to an ugly smile and psychological discomfort. Retained teeth are the cause of various dentition and jaw diseases, they can act as a foreign body, causing damage to neighboring organs, due to spontaneous eruption, can cause root resorption of adjacent permanent teeth or their abnormal eruption. (2)

Correct diagnosis is a determining factor in the success of treating retina teeth. Adequate clinical examination and radiography with a modern orthopantomograph allows you to determine the position of the retarded tooth, which contributes to the optimal choice of treatment methods.

Surgical intervention involves opening the gingival contour under local anesthesia with modern anesthetics. Successful surgical intervention helps to create conditions for conducting orthodontic movement of teeth in the correct position using the bracket system, and to achieve a high and functional result.

Let us take a closer look at some treatment options for retined teeth.

Therapeutic measures are carried out in two stages:

- Surgical - exposure of part of the crown of an uncut tooth;

- orthodontic - pulling a tooth and installing it in the dentition.

There is a method of orthodontic treatment of refined teeth (B. Nikolov, 1985), in which orthodontic removable plates are used with periodic relocation, which acts as an irritant and contributes to the eruption of a refined tooth. The disadvantage of this method is that pressure on the alveolar process can cause a relapse of the follicular cyst and aggravate the patient's condition.

There is also a known method of orthodontic treatment of retined teeth (G.A. Sekletov, 2006), in which the entire crown of a retined tooth is exposed, an impression is taken from a naked crown, an orthodontic crown with a hook for traction is made, which is fixed with phosphate cement to a completely exposed tooth crown, after which the retarded tooth is pulled out according to the standard method. The disadvantage of this method is that it is complex and time-consuming, traumatic at the surgical stage of treatment, because requires significant exposure of the crown of the retina tooth to fix the crown.

There is also a known method of orthodontic treatment of retined teeth (Yu.G. Khudoroshkov, 2008), in which the crown of the retined tooth is exposed, an impression is taken from the half-cut tooth and an individual bracket is made, which is fixed to the retined tooth, and then it is pulled out according to the standard method. The disadvantage of this method is that it is not applicable for stretching retinated (uncut) teeth from follicular cysts, because the depth of such teeth is large, which does not allow to take a cast from them. (3)

Closest to the claimed utility model and a modern method of orthodontic treatment of retined teeth is a method of orthodontic treatment of a retined tooth (RF No. 2436539, Protsuk Ruslan Yurievich (RU))

The essence of the method: Pre-bend in the form of a loop orthopedic wire. Part of the crown of the retined tooth is exposed, to which the ends of the loop of the orthopedic wire are fixed, curved in the shape of the exposed part of the crown. The loop is tied to the orthodontic arch of a standard bracket system. The orthopedic wire is removed when the retained tooth cuts out 1/3 of the crown length. Further treatment is carried out according to standard methods. The method allows to prevent recurrence of the follicular cyst, tooth loss, to establish a deep-lying retarded tooth in the dentition, to simplify the method of stretching an uncut tooth. (four)

This method allows you to avoid a large number of complications when moving in the bones of the retarded tooth. However, there are some disadvantages. Since the claimed method uses the equipment of bracket systems, the cost of the entire treatment in the compartment increases, and the unpredictability of the response behavior of bone tissue to such aggressive influences increases accordingly.

Thus, the question of preliminary verification of the readiness of an adequate response on the part of the body remains urgent, which in the future will allow us to divert the patient’s additional expenses to replacing equipment and eliminating complications.

Purpose of work: creating a system for checking the possibility of placing a retarded tooth in the dentition.

The claimed utility model is presented in Fig. 1 (Bottom view) and Fig. 2 (top view), where

1 - the basis of the apparatus

2 - supporting clamps of the apparatus

3 - functional shoulder of the device

The apparatus for determining the possibility of placing a retined tooth in the dentition is an orthodontic plate and is equipped with a base (1) made of standard polymer, several supporting clasps (2), and a shoulder that carries the functional load (3). The functional arm is located directly above the localization of the defect. The supporting clasps and the functional arm are made of standard blanks for wire clasps with a diameter of 0.5 to 1.2 mm. The device is manufactured laboratory by pre-made prints.

The essence of the utility model is that the ligature wire is fixed at one end on the orthodontic button located on the surface of the tooth, the other is fixed to the hook hooks of the functional shoulder of the device. Further, the apparatus is fixed on the dentition using supporting clasps.

Benefits of the utility model:

- Low cost of the device

- Ease of handling and manufacturing

- Ability to discard the use of the bracket system in advance with unsatisfactory long-term results of using the device

- Saving material resources of the patient, and the doctor’s working time

The proposed utility model will allow much more efficient use of the resources of the doctor and patient, timely and justifiably abandon the use of expensive bracket systems and choose a treatment path with the removal of the retined tooth, with further implantation and restoration of the integrity of the dentition, eliminating a number of complications inherent in the treatment of retined teeth (cysts and etc.)
