Orthodontic zero clearance bracket

Abstract

The invention relates to an orthodontic zero-gap bracket, comprising a bracket body, the bracket body including a bottom plate and a base, the base is provided with an upper limit wing and a lower limit wing on the side away from the bottom plate, and the base is far away from the bottom plate On one side of the upper limit wing and the lower limit wing, there is an arch wire groove for placing a correction arch wire, and the base is provided with a movable groove whose length direction is perpendicular to the length direction of the arch wire groove, and the movable groove and the arch wire groove The grooves are connected, and a pressing block abutting against the correction arch wire is slidably arranged in the movable groove, and the upper limit wing and the lower limit wing are jointly sleeved with a ligation wire that presses the pressing block. Through the above settings, the pressure of the ligation wire pushes the briquetting block against the direction of the orthodontic archwire, and the briquetting block reduces the gap between the orthodontic archwire and the groove of the archwire, thereby improving the torque and correction of the orthodontic archwire during the orthodontic process. expressive effect. And the use of fixing parts is reduced, it is easier to operate in the narrow space in the oral cavity, the user's foreign body sensation is lower, and the user's comfort is improved.

Description

technical field [0001] The invention relates to the technical field of orthodontic brackets, in particular to an orthodontic zero-gap bracket. Background technique [0002] At present, when doctors use orthodontic appliances in clinical practice, common brackets and self-ligating brackets are commonly used. The bracket body is bonded to the tooth surface, and the orthodontic archwire passes through the bracket body. The archwire slot on the top. Ordinary brackets use ligature wires or rubber ligature rings to fix the orthodontic archwires in the archwire grooves of the bracket body, while self-locking brackets rely on sliding or rotating bracket covers, bolt covers or elastic clips to correct the archwires. It is fixed in the groove of the arch wire, so that the force of the orthodontic arch wire drives the bracket body to exert force on the teeth, so as to achieve the effect of oral orthodontics. [0003] Because a series of sizes of orthodontic archwires are used in the ...

AI Technical Summary

Problems solved by technology

However, on the one hand, self-ligating brackets are larger than ordinary brackets, especially when used on the lingual side, and the foreign body sensation of self-ligating brackets is strong; on the other hand, the space on the lingual side is limited, and screws are used to limit the correction archwire. The feasibility of the method is poor, it is difficult for doctors to operate, and the cost is also high, so there is room for improvement
