Orthodontic brackets are devices made of a material such as metal or ceramic that are fixed to the surface of the teeth with a specialized bonding agent during orthodontic treatment to accommodate and hold orthodontic wires and transmit the corrective force to the teeth, thus achieving the purpose of straightening misaligned teeth. Traditional orthodontic brackets need to be secured together with thin wires or rubber bands and orthodontic wires, which are routinely used, and it is precisely these ligature wires or elastic rubber bands that can slow down the course of orthodontic treatment. Because orthodontic treatment to move the teeth need to overcome the frictional resistance between the wire and brackets, the greater the friction, then the need for orthodontic force is also the greater, the slower the speed of movement, orthodontic treatment will take longer. Self-locking bracket slot than the traditional bracket slot more than a locking device, is the so-called “smart clip”, in common parlance is like a gate on the bracket slot, can directly lock the orthodontic steel wire in the bracket slot groove, eliminating the ligature steel wire or rubber ring on the orthodontic steel wire binding, greatly reducing the friction between the steel wire and bracket slot resistance, the tooth The friction resistance between the wires and brackets is greatly reduced, and the force on the teeth will be reduced, the teeth will move faster, and the whole treatment time will be shortened effectively. Self-ligating bracket orthodontic technology has the following advantages compared with the traditional orthodontic technology: 1, shorten the treatment time at present, there are many kinds of self-ligating brackets produced by different companies, and some self-ligating brackets can shorten the course of treatment by more than half a year. 2, prolong the interval between follow-up appointments. 2.Lengthening the interval between follow-ups, the interval between follow-ups of traditional fixed orthodontics is about 4 weeks, that is to say, the patient needs to go to the hospital for adjustment once a month. While the interval of follow-up consultation for self-ligating brackets can be extended to 6-8 weeks, that is to say, patients need to go to the hospital for adjustment once every two months or so. 3.Free from tooth extraction, due to the low friction of self-ligating brackets, the teeth are easier to move, so some patients who used to need tooth extraction can now be treated without tooth extraction. 4.Comfortable and soft orthodontic force greatly reduces the pain during orthodontic treatment.
