The duration of orthodontic treatment varies significantly according to each patient's individual needs and oral structure. The treatment duration depends on various factors such as the complexity of the issues, the treatment method applied, and the patient's compliance with the treatment. Generally, orthodontic treatment is a long-term process. While simpler cases can be resolved within a few months, more complex orthodontic conditions may take 1.5 to 2 years or even longer. In some cases, phased treatment plans may be necessary.
