The process of orthodontic treatment generally includes the development of an orthodontic plan, routine pre-orthodontic treatment, wearing of braces, follow-up appointments and wearing of retainers. 1. Before orthodontic treatment, head and teeth X-rays need to be taken and dental casts need to be made to analyze and formulate a specific plan for orthodontic treatment. 2. After the orthodontic plan is formulated, routine dental treatments, including periodontal treatment, endodontic treatment and tooth extraction treatment, etc., will be performed. 3. Wearing braces: orthodontic archwires are fixed to the teeth with brackets or resin diaphragms, so that the teeth are subjected to orthodontic forces to produce movement. 4. Follow-up: Regular follow-ups are required during orthodontic treatment in order to replace the archwires or diaphragms and to observe the orthodontic effect so that timely adjustments can be made. 5. After orthodontic treatment, a retainer must be worn to maintain the normal alignment of the dental arch, which can effectively prevent the teeth from reappearing with gaps and other symptoms.
