Length of correction time must determine by patients' congestion level, patients' age, health status, maxillofacial development and facial muscle tension. In fact, the correction time is not fixed. Different people have different degree of lesions and different correction difficulty. So the time is also different.

      Correction generally needs for 1 and a half years or 2 years. The time to orthodontic for children is shorter than the adults. What's more, the effect is good. Of course, for more complex teeth correction, the time will be relatively long. So the correction time is different from man to man and must depend on specific circumstances of the case.

      12-14 years old is the best period for children to do orthodontics because the replacement in this period of tooth has been completed. Correcting buckteeth during this period is with short time and the effect is good.

      With the development of medical technology, orthodontics has no time limit. Only orthodontic in adults is relatively long time and great difficult. But as long as you go to the regular professional hospital to correct, time will be shortened and the effect is as good as children.
