Description

Elastic ligation band-shaped arch bracket device TECHNICAL FIELD

[0001] The present application relates to the technical field of dental orthodontic equipment, in particular to an elastic ligation band-shaped arch bracket device. BACKGROUND

[0002] Nowadays, in orthodontics, the commonly used fixed correction technology is divided into two systems: the straight wire arch correction system and the Begg correction system. The straight wire arch correction system is also called the square wire arch correction system, which can make the teeth move in the mesial-distal direction (front-back direction) (horizontal direction) as "overall movement", so the straight wire technology can accurately control the teeth, but the tooth movement is slow and the required correction force is large. The Begg correction system can make the teeth move quickly in the horizontal direction as "inclined movement", which usually first inclines the crown and then inclines the root, and then achieves the purpose of correcting the teeth. The Begg correction system moves the teeth with light force and fast speed, which can significantly shorten the treatment period, but has the disadvantages of complex operation of post-axis (supporting tooth root, adjusting the mesial-distal direction of teeth) and root control (adjusting the position of the lip-tongue direction of the tooth root) in the later stage.

[0003] The bracket in the prior art in the field of orthodontics has a low groove depth, which is not convenient for opening and occlusion, and is not convenient for vertical control of teeth and torque control of teeth in the correction process.
