Orthodontic treatment requires regular review. This is because orthodontics requires the wearing of braces, and the doctor will need to adjust the braces based on each follow-up visit to ensure that the orthodontic treatment is effective. Orthodontic treatment is done by bringing various different orthodontic appliances to correct the problems of teeth alignment, such as overcrowding, large gaps, buck teeth, etc. It can also improve the bite and harmonize jaw deformities. Therefore, during the review process, on the one hand, the current orthodontic results can be determined, and on the other hand, reasonable adjustments and changes can be made to the wearing of retainers according to individual circumstances. The orthodontic review cycle is related to the orthodontic method, and during the orthodontic process, the orthodontist should pay close attention to the orthodontic effect. If there are problems such as poor wear, timely correction can be made to avoid the teeth not moving according to the initial design. The regular fixed orthodontic review cycle is usually 4 to 6 weeks, and patients are advised to follow the doctor’s requirements to ensure good treatment results.
