Making a plan: Making an orthodontic plan: The doctor measures, calculates and diagnoses the type of malocclusion of the patient based on the model, photos and x-rays, and makes a detailed treatment plan suitable for the patient. The doctor then explains the treatment plan to the patient and the patient’s family and asks for the patient’s and family’s opinion. After the treatment plan is determined, the patient or the patient’s family signs the consent form. 3, initial braces: Start the first time in the oral cavity adhesive braces, that is, initial braces. It is more time-consuming than subsequent follow-up visits, which take 1-2 hours.
