Orthodontic treatment is often prolonged because the movement of teeth and bones must be smooth, slow and slow. As in the cure of a disease, it is difficult to predict its total duration. This depends on the severity of the problem, the age of the individual, the equipment used, the cooperation of the patient, and especially, the professional competence of the person who performs it. There are even treatments that are done in several separate phases. In general, although treatment usually takes about two years, the exact duration depends on the individual factors of the patient and this can be confirmed at the time of starting the treatment.
