Dental traction device (6)

The utility model provides a dental traction device, especially a dental traction device with a more complete fixing effect.

Orthodontics, also known as orthodontic appliances or commonly known as braces and braces, are a device used in orthodontics to straighten teeth to the proper occlusal position. Orthodontics are commonly used to improve malocclusion, including buckets, crooked teeth, front and back misbites, open bites, misaligned teeth, or various other dentition defects, etc., for cosmetic or structural purposes. adjustment. Orthodontics are usually used in conjunction with other orthodontic devices, which may be used to open the upper or lower jaw to create space between the teeth; or to change the arc of the teeth and jaws. It also involves changing the face shape, so it is regarded as a type of plastic surgery. Most orthodontic patients are children or adolescents, but in recent years, more and more adults are seeking orthodontic treatment.

Generally speaking, most aligners pull the teeth through the dental arch wire, thereby changing the position of each tooth through a progressive adjustment method, and there are many ways to pull the dental arch wire, such as setting free hooks on the dental arch wire .

The general free hook is composed of a seat that is engaged with the dental arch line and a support rod that is sheathed with a rubber band. There are often grooves on the seat body to clamp on the dental arch wire, and ridges perpendicular to the extending direction of the grooves are arranged in the grooves as a way to increase friction and fixation. However, this fixation method is often not stable enough, which may cause the free hook to slip on the dental arch line, resulting in an incomplete correction effect.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the applicant of the present invention and the relevant manufacturers engaged in this industry are eager to research and improve.

Therefore, in view of the above-mentioned deficiencies, the applicant of this new model collects relevant information, evaluates and considers from various parties, and uses years of experience accumulated in this industry, through continuous trials and revisions, to design a more complete fixed effect. Patent holder of a new type of dental traction device.

The main purpose of the new model is to achieve a more complete fixing effect through the cooperation of the upper arc top pressing part and the lower arc top pressing part with the upper inclined part, the upper groove part, the lower inclined part and the lower groove part.

In order to achieve the above-mentioned purpose, the main structure of the present invention includes: an upper catch portion, an extension portion connected to the upper catch portion, and a lower catch portion connected to a side of the extension portion away from the upper catch portion. The seat body, a traction main body set on the seat body, a card slot located on the seat body and located between the upper catch part, the extension part, and the lower catch part; Connected openings, an upper sloping surface provided on the upper latching portion, a lower sloping portion provided on the lower latching portion, an upper sloping portion located on the upper latching portion and located on one side of the upper sloping portion a circular arc top pressing portion, a lower circular arc top pressing portion provided on the lower catch portion and located at one side of the lower inclined portion, an upper groove portion provided between the upper catch portion and the extension portion, and A lower groove part is arranged between the lower locking part and the extending part.

With the above structure, the user can put the dental arch wire into the clip slot through the opening, thereby placing the seat body on the dental arch wire, and then the user can press the seat body through the clamping tool, so that the lower part can be lowered. The latching part is bent and pushed upwards, so as to cooperate with the extension part and the upper latching part to fix the dental arch wire.

When the lower clamping part is bent, the overall space of the clamping groove will be reduced, so that the upper inclined part and the lower inclined part will push the dental arch wire in the direction of the extension part, so that the dental arch wire will contact the extension part and pass through. The structure of the upper groove part and the lower groove part increases the area that fits with the extension part, thereby increasing the contact area with the seat body, and at the same time, the upper arc top pressing part and the lower arc top pressing part will be pushed to press on the upper and lower sides of the dental arch line. Moreover, since the extension direction of the upper circular arc top pressing part, the lower circular arc top pressing part, the upper slope part, the upper groove part, the lower slope part, and the lower groove part is the same as the direction of the clamping groove, it is possible to increase the The contact area with the dental arch wire can achieve a more complete fixation effect.

With the above technology, it is possible to break through the problem that the fixed effect of the conventional free hook is not complete enough to achieve the practical progress of the above advantages.
