With the significant improvement of China’s economic level and the enhancement of people’s oral health care awareness, more and more patients choose to improve the alignment of their teeth through orthodontic treatment to get a charming smile. After a detailed orthodontic analysis and diagnosis and orthodontic design, patients are then faced with the problem of choosing orthodontic braces, and they do not know how to choose from a wide variety of brackets. Self-locking brackets are a new technology that has emerged in recent years, and its main advantage is that it can greatly reduce the frictional resistance between the wires and brackets. Because it adds a door to the brackets, the orthodontic wire can be directly locked in the groove of the brackets, eliminating the need for ligature wire or rubber bands to bind the orthodontic wire. Self-locking brackets orthodontic technology has the following advantages over traditional orthodontic techniques: 1. Shorten the treatment time. Teeth move quickly with low friction. 2.Lengthen the interval between follow-up visits. The follow-up interval for traditional fixed orthodontics is about 4 weeks, which means that the patient needs to go to the hospital once a month for adjustment; while the follow-up interval for self-ligating brackets can be extended to 8 to 10 weeks, giving the archwire sufficient time to move the teeth. In other words, the patient can go to the hospital once every two months for adjustment, which can minimize the delay of the child’s school and recreational time. 3.Eliminate tooth extraction. Due to the extremely low friction of self-ligating brackets, it is easier to move the teeth, so some patients who used to need extraction treatment can now be treated without extraction. 4.Comfortable and gentle orthodontic force makes orthodontic patients feel much less discomfort. From a hygiene standpoint, children can very easily clean the entire bracket with a soft-bristled toothbrush.
