During the period of orthodontic treatment, the role of accessories during the correction period mainly includes two points: strengthening retention and strengthening the force on the teeth. This is more conducive to the smooth progress of the entire tooth correction process and effectively shortens the time of the entire tooth correction. Generally, the time required for minors to correct their teeth is about one and a half to two years, while the time for adults to correct their teeth is about two to two and a half years.
1. Strengthen retention
Although invisible braces can be worn directly on the teeth and fit the teeth, the use of accessories can better fix the braces on the teeth and make the braces and teeth fit better.
2. Strengthen the force on the teeth
Because the invisible braces are worn, the teeth are completely wrapped in the braces. At this time, if there are accessories, the direction of the movement of the corrected teeth can be better controlled, so that the braces can control the movement of the teeth more accurately.
There are many types of accessories, and different types have different functions. For example, rectangular accessories can control the movement of molars, and rotating accessories are used to control the movement of canines and premolars.
