Orthodontic auxiliary anterior tooth depressing device

Abstract

The utility model provides an orthodontic auxiliary anterior tooth depressing device, and mainly relates to the technical field of orthodontics. The orthodontic auxiliary anterior tooth depressing device comprises a main arch tube, a connecting tube is fixedly arranged at the bottom of the main arch tube, an auxiliary arch tube is fixedly arranged at the bottom of the connecting tube, and the auxiliary arch tube and the main arch tube are obliquely arranged. The device has the beneficial effects that the device can be added and taken down at any time clinically, and does not need to be bonded with a dental surface, so that the chair-side time is saved; an auxiliary bow does not need to be additionally bent, and a common nickel-titanium wire can enter the auxiliary bow tube; pressing force can be reduced to cross the canine teeth, and stress interruption is avoided; and the main anchorage tooth is arranged between the two back teeth, so that only one tooth is stressed, and the back teeth are prevented from being extended too much.

Description

Technical Field

[0001] The utility model mainly relates to the technical field of oral orthodontics, in particular to an orthodontic auxiliary anterior teeth lowering device. Background Art

[0002] In orthodontics, the problem of deep overbite of anterior teeth is often encountered. The usual solutions are: 1. Implantation of 1-2 anchor pins in the anterior area; 2. Rocking arch of the main arch wire; 3. Depression arch of the double-tube buccal tube of the molar; 4. Toad arch auxiliary arch. The above methods have many problems: implantation of 1-2 anchor pins in the anterior area requires additional costs and is invasive. For some patients with soft bones, the anchor pins are easy to loosen and fall off; the rocking arch of the main arch wire will produce an excessive lip tilting effect; the depression force of the anterior teeth will be on the canines, with a stress interruption effect, which cannot be transmitted to the incisor; the depression arch of the double-tube buccal tube of the molar requires re-bonding of the buccal tube of the molar, and has a stronger lifting effect on the individual molars. The toad arch auxiliary arch requires strong arch wire bending ability, which makes the operation time long and has high requirements for the doctor. Utility Model Content

[0003] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0004] An orthodontic auxiliary anterior teeth lowering device comprises a main arch tube, a connecting tube fixedly arranged at the bottom of the main arch tube, an auxiliary arch tube fixedly arranged at the bottom of the connecting tube, and the auxiliary arch tube is arranged obliquely with the main arch tube.

[0005] The main arch tube is arranged in a U-shape, and flanges are symmetrically fixedly arranged on the open ends of the main arch tube.

[0006] The auxiliary arch tube is hollow and is inclined to the main arch tube.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] The utility model is universal for upper and lower left and right, has a simple structure, is easy to install and use, can be added and removed at any time in clinical practice, does not need to be bonded to the tooth surface, and saves chairside time; no additional bending of the auxiliary arch is required, and commonly used nickel-titanium wire can enter the auxiliary arch tube; the lowering force can cross the canine to avoid stress interruption, and the force acts directly on the incisor, and the tooth lowering efficiency is high; it can be entered from the end of the main arch wire, or it can be directly clamped and retained (there is no need to remove the main arch wire); the main anchor tooth is between the two posterior teeth, and only one tooth will be subjected to force, avoiding excessive elongation of the posterior teeth.

[0013] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalent forms also fall within the scope defined in this application.

[0014] In conjunction with the accompanying drawings, an orthodontic auxiliary anterior teeth lowering device includes a main arch tube 1, a connecting tube 2 is fixedly set at the bottom of the main arch tube 1, an auxiliary arch tube 3 is fixedly set at the bottom of the connecting tube 2, and the auxiliary arch tube 3 is set obliquely to the main arch tube 1.

[0015] The main arch tube 1 is arranged in a U-shape, and a flange 4 is symmetrically fixedly arranged on the open end of the main arch tube 1.

[0016] The auxiliary arch tube 3 is hollow and inclined relative to the main arch tube 1 , with an angle of 35° between the auxiliary arch tube 3 and the main arch tube 1 .

[0017] When the device is in use, the main arch wire is inserted into the main arch tube 1. The main arch wire can be inserted directly from the end of the arch wire or clamped in from the middle.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
