During treatment, orthodontic patients should have regular subsequent consultations with the orthodontist so that their treatment progress can be promoted. The orthodontist will change the arch wire at the right moment referring to the tooth movement and stabilization conditions. When each new arc wire is used, the teeth will be made in a better order. The key to achievement of expected effects in a fast way is to follow the orthodontist's guidance and to pay attention to the oral hygiene and diet. If having any unusual reactions, patients should contact with their orthodontist in time.
