At present, the most commonly used appliances are fixed appliances and invisible appliances without brackets. The former has the advantages of low friction, fast correction speed, low price and little damage; However, the disadvantage is that the bracket needs to be attached to the tooth surface, which can not be disassembled at will during orthodontics, and the appearance is not very beautiful, so it is difficult to care for oral hygiene during orthodontics.
