1, improve the efficiency of the system of orthodontics, shorten the treatment time: because self-ligating brackets greatly reduce the internal friction of the system, the use of light force orthodontic system, improve the efficiency of tooth movement, can shorten the course of treatment for more than six months; 2, extend the interval between visits: the interval between visits for traditional fixed orthodontics is about 4 weeks, that is, the patient needs to go to the hospital once a month to adjust; and the interval between visits for the use of self-ligating brackets orthodontics 3, elimination of tooth extraction: because the friction of self-ligating brackets is extremely low, the movement of teeth is easier, so some patients who used to need extraction treatment can now be treated without extraction; 4, patient comfort is enhanced: no wire and elastic ligature, the orthodontic force is light so that patients feel much less discomfort; 5, narrower brackets, brackets Wide spacing, so easy to clean, good oral hygiene, easy to be accepted by patients.
