The two have their own characteristics, the main difference is that the nature of different, different principles of action, different features, as follows:
A, nature of different
1, self-locking brackets
Self-locking orthodontic brackets refers to the orthodontic treatment, with a special bonding agent fixed on the surface of the teeth of a metal or ceramic and other materials made of the device.
2, brackets
The brackets are an important part of the fixed orthodontic technique, with adhesive directly bonded to the surface of the crown, the archwire through the brackets and the teeth to apply various types of orthodontic force.
Two, the role of different principles
1, self-locking brackets
used to accommodate and fix the orthodontic wire, the transmission of orthodontic force to the teeth, so as to achieve the purpose of orthodontic treatment.
2, brackets
made of stainless steel, bioceramic or composite resin, its main role is to fix the arch wire, so that the arch wire to play a better role in the transmission of orthodontic force, so as to control the teeth three-dimensional movement, to achieve the purpose of orthodontic treatment.Three, different features
1, self-locking bracket
Self-locking bracket than the traditional bracket has a locking device, which can directly lock the orthodontic wire in the bracket grooves, eliminating the ligature wire or rubber band on the orthodontic wire binding, greatly reducing the friction resistance between the wire and the bracket, the teeth by the force will also reduce the speed of movement of the teeth will accelerate the whole treatment time will be effectively shortened. treatment time will be effectively shortened.
2, bracket
The need for fine steel wire or rubber band and orthodontic wire fixed together, this is the conventional practice, and it is precisely these ligature wire or elastic rubber band will slow down the course of orthodontic treatment. Because orthodontic treatment to move the teeth need to overcome the frictional resistance between the wire and the brackets, the greater the friction, then the greater the need for orthodontic force, the slower the movement, the longer orthodontic treatment takes.
