Description

Tooth orthodontic tractor

Technical Field

The utility model belongs to the technical field of orthodontic tools, and particularly relates to a tooth orthodontic tractor.

Background

Abnormal growth of teeth, abnormal growth of jawbone, bad habit such as sucking fingers, bad eating habit and/or genetics during infant period may cause the teeth and the mouth to not grow in proper positions, resulting in irregularly arranged teeth, malocclusions (a state in which occlusion of teeth is not matched), or facial protrusion. Irregular arrangement of teeth, malocclusions, or facial protrusions may cause personal relationships to be inactive and also reduce even mastication of food as a basic function of teeth. Accordingly, in order to solve these problems, it is increasingly common in orthodontic treatment to move teeth by applying constant force to the teeth, thereby reorganizing an alveolar bone surrounding the teeth. Orthodontic, also known as orthodontics, is the correction of malformation of teeth. Orthodontic is mainly orthodontic tooth correction.

In the conventional orthodontic procedure, one end of the traction unit is connected to an anchor implanted in the jawbone or the alveolar bone, and the other end thereof is connected to the lower protrusion of the bracket at an angle (an angle of θ1 with respect to the horizontal direction of the anchor). In this case, since the connection angle of the traction unit connected to the bracket is inclined with respect to the anchor, a pulling force F1 is applied to the tooth T during orthodontic treatment. For this reason, the tooth T and the tooth root T' are not pulled horizontally, and the tooth T is pulled in the inclined direction inclined by the angle θ2. Therefore, a skew phenomenon occurs. In the conventional orthodontic device, teeth are pulled obliquely when orthodontic treatment is performed by connecting a traction unit with a bracket-type orthodontic device. Therefore, it is difficult to perform normal orthodontic treatment, and the orthodontic period is long.

Disclosure of Invention

An object of the present utility model is to provide an orthodontic retractor which solves the problems that in a conventional orthodontic device, when an orthodontic treatment is performed by connecting a traction unit with a bracket type orthodontic device, teeth are pulled obliquely, and thus, a normal orthodontic treatment is difficult to perform and an orthodontic period is long.

Through setting up the arc arch for the hook can bypass the gum, avoids oppressing the gum.

In one possible design, the arcuate projections form a spacing of 0.67mm to 0.73mm from the plane of the tooth attachment unit.

In one possible design, the tooth attachment units are curved such that the tooth attachment units are concave on one side of the teeth; the bulge and the connecting rod are positioned on the same arc-shaped surface. The tooth attaching units are arranged to be arc-shaped, so that one side of each tooth attaching unit, which is attached to the teeth, is sunken; the bulge and the connecting rod are positioned on the same arc surface, so that the tooth and the gum can be more attached, and the foreign body sensation is reduced.

In one possible design, the tooth attachment unit is provided with a mesh on the side that fits the teeth. The tooth attachment units are arranged as grid sheets, so that the bonding is firmer and the tooth attachment units are not easy to fall off.
