Description

A bonded multi-purpose tow hook

technical field

The utility model relates to the technical field of clinical orthodontics, in particular to an adhesive multipurpose traction hook.

Background technique

Anteriorly impacted mandibular molars are a common malocclusion in clinical practice. At present, the orthodontic appliances for correcting such malocclusion mainly include traditional fixed appliances, vertical springs, cantilever arches, and micro-implanted screws. It has its shortcomings. When the traditional fixed appliance molars the mandibular teeth vertically, due to the large deformation of the arch wire, it is easy to cause the deformation of the dental arch, and the long course of treatment will affect the alignment of other teeth, which will increase the clinical orthodontic treatment. time, the magnitude and direction of the orthodontic force of the vertical spring and the cantilever arch are not easy to be accurately controlled, and the bending method is complicated, and the chairside operation time is long. Loose, easy to be covered by soft tissue, etc., so the failure rate of this method is high. In view of this, we propose a bonded multi-purpose traction hook.

Utility model content

The purpose of this utility model is to provide a bonded multi-purpose traction hook to solve the problem of large deformation of the arch wire in the above background technology, which can easily cause deformation of the dental arch, and the problem of a long course of orthodontic treatment.

In order to achieve the above object, the utility model provides the following technical solutions:

An adhesive multipurpose towing hook, comprising an adhesive part, the upper surface of the adhesive part is provided with a protrusion, one side of the protrusion is provided with a body, and the end of the body is provided with a traction department.

Preferably, the protrusion and the bonding part are integrally formed.

Preferably, the body part and the traction part are integrally formed.

Preferably, the body is in the shape of a long arm with a length of 7 mm.

Preferably, the end of the pulling part is hemispherical.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model can realize the change of traction angle by adjusting the direction of the body part and the traction part according to the inclination degree of the affected tooth, and the action point is transferred to the root side of the molar, which is closer to the impedance center of the molar, and then changes the rotation center of the forward-leaning molar , to achieve efficient vertical and axial control of the affected tooth, by adjusting the bonding position and changing the size of the rubber ring to add force, without disassembling the arch wire, saving the doctor's chairside operation time, not affected by the diameter and material of the arch wire Restricted, it can be placed in the early stage of treatment, effectively shortening the course of treatment, simplifying treatment steps, low product cost, convenient and quick to use, and easy to promote.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

In describing the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", Orientation indicated by "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. Or the positional relationship is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the referred device or element must have a specific orientation, be configured in a specific orientation, and operation, and therefore cannot be construed as a limitation of the utility model.

Example 1:

An adhesive multi-purpose tow hook, as shown in Figure 1, includes an adhesive part 1, the upper surface of the adhesive part 1 is provided with a protrusion 10, and one side of the protrusion 10 is provided with a body part 2, the body part 2 The end is provided with traction part 3.

In this embodiment, the bonding part 1 fits the surface of the tooth, and is directly bonded and fixed near the neck of the molar crown, which is easy to operate. The body part 2 is in the shape of a long arm with a length of 7mm. Part 3 is an integral molding structure.

Further, the protrusion 10 and the bonding part 1 are integrally formed, and the body part 2 and the traction part 3 are separated from the tooth surface through the protrusion 10, effectively preventing the body part 2 and the traction part 3 from pressing on the gums, which is beneficial to reduce the burden on the gums .

Specifically, the end of the traction part 3 is in a hemispherical shape, which can prevent the end of the traction part 3 from stabbing the gums, thereby helping to protect the gums.

When the bonded multi-purpose traction hook of the utility model is used, firstly, it is determined according to the degree of inclination of the affected tooth, and the bonding part 1 is attached to the surface of the tooth so that it is bonded to the crown surface of the forward molar The neck near the teeth, through the protrusion 10, the body part 2 and the traction part 3 are separated from the tooth surface, effectively preventing the body part 2 and the traction part 3 from pressing on the gums, which is beneficial to reduce the burden on the gums;

When adjusting the bonding position of the bonding part 1, according to the change of the traction angle, the body part 2 and the traction part 3 can be used together with the rubber ring and invisible aligners without brackets, fixed aligners, micro-implanted nails, etc. Efficient vertical and axial control of the forward molars helps to reduce the doctor's chair time.
