The whole process of orthodontic treatment can be basically divided into several steps, such as taking pictures for modeling analysis, making orthodontic plan, confirming the plan, bonding brackets, regular follow-up and wearing retainers. 1. Taking pictures for model analysis: Before starting orthodontic treatment, firstly, we should go to the orthodontic department of professional and regular dental hospital to take panoramic pictures and lateral pictures of the head, and take the model of the mouth for comprehensive analysis of the difficulty of orthodontic treatment. 2. Formulation of orthodontic program: the orthodontist will formulate a suitable orthodontic program for the patient to choose according to the patient’s degree of malocclusion, as well as treatment expectations. 3. Confirmation of the plan: After comprehensively analyzing personal wishes and economic consumption level, the patient confirms the plan suitable for him/her and reaches a unified opinion with the doctor after signing the informed consent. 4. Bonding brackets: After the patient determines the plan, the doctor will first carry out the basic cleaning of the teeth in the mouth, and bond the fixed brackets on the lip and side of the teeth to provide the basis for the distribution of orthodontic traction in the later period. 5. Regular follow-ups to increase the force: Because orthodontics is a relatively complex and long process, the general fixed brackets need about 4 to 6 weeks of follow-ups to replace the arch wire so as to gradually increase the traction force of orthodontics. 6. Wearing a retainer: after the completion of orthodontic treatment, it is necessary to remove the brackets and make a retainer, generally the retainer needs to be worn for about one year to two years to basically complete the orthodontic treatment.
