Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical instrument equipment, in particular to a milk tooth orthodontic self-locking corrector. BACKGROUND

[0002] The brackets currently used in the field of orthodontics mainly include two categories: traditional ligation wire brackets and self-locking brackets. The self-locking brackets have been widely used in clinical practice because they reduce the friction between the arch wire and the bracket, simplify the clinical operation process, and improve the treatment efficiency. The design of the self-locking bracket aims to fix the arch wire through its own locking mechanism, thereby avoiding the problems caused by the traditional ligation wire, such as bracket loosening caused by ligation wire breakage or irritation to the oral soft tissue. In recent years, with the continuous progress of oral medical technology, the application range of self-locking brackets has gradually expanded, and they have shown significant advantages, especially in the treatment of children's orthodontics.

[0003] There is no self-locking bracket designed specifically for milk teeth on the market, only permanent tooth brackets. Doctors generally use two solutions when needed:

[0004] 1. Directly use permanent tooth brackets. Because of the differences in size, angle, etc. between milk teeth and permanent teeth, patients have a strong sense of foreign body in the mouth, and the brackets cannot completely match the milk teeth, making the treatment difficult and ineffective.

[0005] 2. Use smaller tooth positions (such as lower 12 teeth, i.e. lower incisors) in permanent tooth brackets for milk teeth. Although these brackets are smaller in size, they are still not small enough, and their torque angle, axis inclination angle, and bottom plate arc data are completely different from those of milk teeth, also causing the same problems of difficult treatment and poor results.

[0006] As can be seen, there are many problems in using permanent tooth brackets for milk tooth treatment. The size of the brackets is too large, causing a strong sense of foreign body in the mouth, and the size and angle of the brackets do not match the milk teeth, making the treatment difficult and ineffective. A new solution designed specifically for milk teeth is urgently needed to solve the above problems. CONTENT OF THE INVENTION
