With the improvement of living standards and the development of network information, orthodontics has become more and more important. But the consultation found that patients do not understand the conventional process of orthodontics, often to speed up treatment and do something contrary, here the orthodontic treatment process of Peking University Dental Hospital Orthodontic Department is summarized, other formal orthodontic institutions are basically similar, I hope it will help. First of all, it should be clear that orthodontic treatment is a complex and long process, which requires good cooperation between the doctor and the patient in order to achieve satisfactory orthodontic results. Generally speaking, it takes about 2 years for adolescent orthodontics and 2.5-3 years or even longer for adult orthodontics. The treatment time mainly depends on the patient’s age, orthodontic difficulty, tooth movement speed and cooperation, etc. It is not up to the doctor to decide. I. Initial consultation, consultation treatment The first time you need to register a consultation number and wait in line to be called. In order to facilitate the majority of students to visit, North University Orthodontics consultation in winter and summer is not limited, but you are still recommended to come early. Doctors will see the first and second time together, so we hope you will understand that you need to wait a little longer when there is a concentration of patients. The consultation time is about 10~20 minutes, the doctor will conduct a preliminary oral examination, tell you where your problem is and its severity, possible orthodontic treatment methods and the approximate course of treatment and cost, if you decide to treat, you can build a file, take X-rays (if you have taken dental films before, you can bring them here), and arrange the next follow-up appointment.

The consultation will take about 30 minutes, including: (1) The doctor will analyze and measure your dental impressions, x-rays and other information, and design one or more treatment plans that are suitable for you from the perspective of the best treatment effect.

After a long treatment process, the orthodontic appliances can be removed when the desired treatment effect is achieved, except for patients with early orthodontic treatment during the period of tooth replacement, who need to wear retainers. (1) Removal of the intraoral appliance, removal of attachments and bonding, and polishing of the tooth surface. (2) Bite the dental mold. (3) Take post-treatment radiographs. (4) Take post-treatment radiographs. (5) Design and fabricate the retainer. (6) Make an appointment to wear the retainer and explain the precautions to be taken, and watch the educational video during the retention period. It is recommended that each orthodontic patient be reviewed once every six months. Routine review: one month after aligner removal → three months → six months → one year Wearing retainers after orthodontic treatment is very important and is part of the orthodontic treatment. This is because when the teeth are aligned, they are not yet stable in their new position, and it allows your teeth to be stabilized in their new position, giving them enough time to undergo biological alterations so that you can actually have a straight set of teeth. If you wish to keep your teeth in the same position as they have been straightened, be sure to wear retainers as prescribed by your doctor.
