Technical Field

The invention belongs to the field of orthodontic treatment, and particularly relates to an impacted tooth auxiliary traction device and a traction method.

Background

Impacted teeth can cause arch deformity, affect the chewing function of patients and the beauty of the face. The correction of impacted teeth is very essential both for health and for aesthetic appearance.

However, the correction of impacted teeth has been a difficult point in orthodontic treatment. The impacted teeth comprise impacted anterior teeth and impacted premolars. The clinical manifestations of impacted anterior teeth and impacted premolars are: firstly, the normally replaced anterior teeth and premolar teeth are not germinated or insufficiently germinated in time, and gaps are generated at the positions of emergence, which are expressed as 'missing teeth'; and secondly, the normally replaced anterior teeth and premolars are germinated and ectopically or completely buried, and the position of the teeth is occupied by adjacent teeth, which is expressed as 'completely deviated midline and missing teeth'.

The image shows that the impacted anterior teeth and impacted premolars can be impacted in any direction, and are often accompanied by abnormal development of tooth roots, which is characterized in that the tooth roots are shorter than the same-name teeth on the opposite side, the apical foramen can not be completely closed, the root tips of the tooth roots are bent or the crown roots are angled. For the cases of impacted teeth in the stage of replacing teeth, because the impacted teeth are too deep or the root development condition is not good enough, the traditional correction technical means is limited and the traction difficulty is high, the patient has a risk that the impacted teeth are pulled out from multiple sides, and the normal function and the attractiveness of the occlusal surface of the teeth are recovered through later-stage restoration treatment or the closing of the gap between the impacted teeth after the teeth are pulled out.

In recent years, patients with impacted anterior teeth and premolars in orthodontic clinic are gradually increased, and the expectations of patients on orthodontic treatment are gradually increased, and it is often desired to retain impacted teeth through orthodontic treatment, which brings greater challenges to the clinical work of orthodontists.

At present, the traditional impacted tooth traction method mainly has the following defects: the method mainly comprises the steps that an impacted tooth is directly pulled on a stainless steel square wire, the moving direction of the pulled impacted tooth is single, the time that the dental crown of the impacted tooth is buried in a bone is long, the pulling resistance is large, and the absorption of the dental root of the adjacent tooth is easily caused when the impacted tooth close to the dental root of the adjacent tooth is pulled; and (II) for the cases that the impacted tooth crown is positioned on the palatal side or the impacted tooth is inverted, the traditional direct traction cannot pull the impacted tooth into place.

In conclusion, the impacted tooth traction mode in the existing orthodontics often causes the inclination of adjacent teeth, even risks of root pressing absorption of the adjacent teeth, long traction time and poor traction effect.

Disclosure of Invention

The invention provides an impacted tooth auxiliary traction device, which aims to solve the problems that in the prior art, an impacted tooth traction mode in orthodontics often causes adjacent teeth to incline, even risks of root pressing absorption of the adjacent teeth occur, the traction time is long, and the traction effect is poor.

In order to achieve the technical purpose, the following technical scheme is proposed:

the utility model provides a hinder supplementary draw gear of living tooth, includes circle bent, draft arm and fixed arm, circle bent both ends all are connected with the draft arm, and two draft arms all are connected with the fixed arm.

Furthermore, the two traction arms are symmetrically connected to the ring curve. The symmetrical draft arms provide better control of draft forces.

Furthermore, two ends of the two fixed arms are connected with metal buckles. The button is known to those skilled in the art. The fixing arms connected with the metal buttons can be directly connected by the metal buttons, and the fixing arms which are not connected with the metal buttons fix the fixing arms on the bracket through the ligature wires.

Furthermore, the ring, the traction arm and the fixing arm are integrally formed. The integrated into one piece not only is convenient for bend the system, can also improve life.

Furthermore, the traction device is formed by bending a stainless steel wire.

An impacted tooth auxiliary traction method comprises the auxiliary traction device, wherein a fixed arm is fixed on a main arch wire, and a loop is fixed on an impacted tooth; the impacted tooth is dragged by controlling the size of the included angle between the traction arm and the fixed arm and the included angle between the traction arm and the tooth surface connected with the main arch wire.

Further, the end of the fixing arm extends out of at least one bracket.

An assisted traction method for impacted teeth is characterized by comprising the following steps:

A. bending an auxiliary traction device;

B. fixing the fixing arm on the main arch wire to ensure that the tooth surface connected with the traction arm and the main arch wire has an included angle;

C. the curvy is fixed on the impacted tooth.

The included angle between the traction arm and the fixing arm and/or the included angle between the traction arm and the tooth surface connected with the main arch wire are/is adjusted.

By adopting the technical scheme, the invention has the following advantages:

1. the impacted tooth traction mode can avoid the phenomena of inclination and root pressing absorption of adjacent teeth, and has the advantages of short traction time and good traction effect.

2. The auxiliary traction device is connected to the main arch wire, and can provide forces in the jaw direction and the horizontal direction to the impacted tooth through the action of the traction arm, so that the impacted tooth is favorably pulled and erupted from the cheek side or the jaw side, the quantity of the impacted tooth embedded in a bone is reduced, the purpose of exposing the dental crown of the impacted tooth as early as possible is achieved, and the traction is more convenient.

3. When the impacted tooth completely and horizontally buried is pulled, the buccal side or the jaw side of the impacted tooth is pulled to sprout, and the pressed root of the impacted tooth can be prevented from being exposed.

4. The double-side fixing arms disperse the reaction force of traction, reduce the influence on adjacent teeth and avoid the phenomenon of inclination or root pressing absorption of the adjacent teeth.

5. The invention has simple structure and convenient clinical operation; under the condition of not replacing the auxiliary device, only the included angle of the tooth surface connected with the main arch wire by the traction arm needs to be adjusted, so that the operation time of a doctor can be shortened, and the fatigue of the doctor is reduced.

6. The invention performs elastic traction and stress application by adjusting the included angle of the tooth surface connected with the main arch wire by the traction arm, thereby gradually drawing the impacted teeth to be in place and having the advantages of simplicity and high efficiency.

7. The invention achieves stress application by adjusting the angle between the traction arm and the fixed arm, and has the advantage of improving the traction efficiency of the impacted tooth.
