Example Embodiment

[0044] Example 1

[0045] Such as figure 1 As shown, this embodiment provides an auxiliary traction device for impacted teeth, which includes a loop 1, a traction arm 2, and a fixed arm 3. Both ends of the loop 1 are connected with a traction arm 2, two traction arms 2 Both are connected with a fixed arm 3.

[0046] Further, the two traction arms 2 are symmetrically connected to the loop 1. The symmetrical traction arm 2 can better control traction.

[0047] Further, both ends of the two fixed arms 3 are connected with metal buckles 4. The metal buckle 4 is available to those skilled in the art. Such as image 3 As shown, the fixed arm 3 connected with the metal buckle 4 can be directly connected with the metal buckle 4, and the fixed arm 3 without the metal buckle 4 is fixed to the bracket 6 by a ligature wire.

[0048] Further, the loop curve 1, the traction arm 2 and the fixed arm 3 are integrally formed. One-piece molding not only facilitates bending, but also improves service...

Example Embodiment

[0050] Example 2

[0051] Such as Figure 4 , Figure 5 , Image 6 with Figure 7 As shown, this embodiment provides an auxiliary traction method for an impacted tooth, which includes the auxiliary traction device described in Embodiment 1. The fixed arm 3 is fixed on the main arch wire 5, and the loop 1 is fixed on the impacted tooth ; By controlling the angle between the traction arm 2 and the fixed arm 3, and controlling the angle between the traction arm 2 and the main archwire 5, the impacted tooth can be traction.

[0052] Further, the end of the fixed arm 3 extends beyond one bracket 6 at least.

[0053] An assisted traction method for impacted teeth, which is characterized in that it comprises the following steps:

[0054] A. Bending auxiliary traction device;

[0055] B. Fix the fixed arm 3 on the main arch wire 5 so that the tooth surface connecting the traction arm 2 and the main arch wire 5 has an angle;

[0056] C. Fix the circle curve 1 on the impacted tooth.

[0057] Adju...

Abstract

The invention belongs to the field of medical equipment, and specifically relates to an auxiliary impacted tooth traction device and traction method. The traction device includes a loop, traction armsand fixing arms; the two ends of the loop are connected to the traction arms; and the two traction arms are connected to the fixing arms. Through the impacted tooth traction mode, the inclining of adjacent teeth and root resorption can be avoided; and the traction device and traction method have the advantages of being short in traction time and good in traction effect.

Description

technical field [0001] The invention belongs to the field of orthodontics, and in particular relates to an auxiliary traction device and a traction method for impacted teeth. Background technique [0002] Impacted teeth can cause dental arch deformities, affecting the patient's masticatory function and facial appearance. Therefore, the orthodontic treatment of impacted teeth is very necessary for both health and aesthetics. [0003] However, the treatment of impacted teeth has always been a difficult point in orthodontic treatment. Impacted teeth include impacted anterior teeth and impacted premolars. The clinical manifestations of impacted anterior teeth and impacted premolars are as follows: ①The normally replaced anterior teeth and premolars did not erupt in time or erupted insufficiently, and gaps occurred at the eruption position, which manifested as "missing teeth"; ②The normally replaced anterior teeth and anterior Ectopic or completely embedded molar eruption, the...
