Background
With the development of orthodontic technology and the increasing demand of people on beauty, the tongue side invisible orthodontics is becoming the hot door of orthodontics.
In the traditional labial orthodontics, the bracket is positioned on the labial side of the tooth, which affects the beauty of the patient, so that many people abandon the orthodontic treatment. The lingual bracket appliance is positioned on the lingual side of the teeth, so that complete invisibility can be really realized, and the requirements of a plurality of adult patients with high aesthetic requirements are met.
The lingual bracket is usually made of materials such as metal or ceramic, and in orthodontic treatment, the lingual bracket is firstly fixed on the surface of a tooth by adopting a special adhesive, and then an orthodontic arch wire is fixed by the lingual bracket, so that the orthodontic force of the orthodontic arch wire can be transmitted to the tooth, and the orthodontic effect is achieved.
If the application number is: the Chinese patent of CN201720219317.3 discloses a lingual bracket, which has the technical key points that: the orthodontic bracket comprises a base plate, a bracket body arranged on the base plate, a groove arranged on the bracket body and used for penetrating an orthodontic arch wire, and a positioning piece arranged on the base plate and used for positioning the tongue side bracket. This scheme passes through the setting of setting element, reaches the purpose that makes tongue side support groove can install fast. However, the conventional lingual bracket needs to use a ligature wire or a rubber ring to maintain the contact between the orthodontic arch wire and the bracket, so that a larger pressure is generated on the orthodontic arch wire, the friction force between the orthodontic arch wire and the arch wire groove is increased, the normal movement of the orthodontic arch wire is hindered, and the orthodontic treatment effect is influenced.
And CN201720219317.3 also discloses that two first fins are protrudingly disposed at the end of the first operating wing far from the second operating wing, two second fins are protrudingly disposed at the end of the second operating wing far from the first operating wing, and the two second fins extend outwards, and the first fins and the second fins are both disposed in a bent manner and the orientations of the first fins and the second fins are opposite. In addition, a first positioning groove is hollowed between the two first wing pieces, a second positioning groove is hollowed between the two second wing pieces, the opening directions of the first positioning groove and the second positioning groove are opposite, and the bottoms of the first positioning groove and the second positioning groove are arc-shaped. The arch wire penetrates through the groove, so that a plurality of tongue side brackets are connected, the rubber ring is sleeved from the first wing piece and the second wing piece, the rubber ring is tightly bound on the bottom support under the blocking of the first wing piece and the second wing piece, the arch wire and the tongue side brackets are tightly bound, and finally, the positioning piece can be reserved and can also be bent and broken to complete installation. That is, each side of the traditional tongue side bracket is provided with 2 fins, which is convenient for ligaturing wires or sleeving rubber bands, but the bracket bodies of the two fin structures are not stable and firm enough, and the production is troublesome.
