For children who have not changed their teeth, some serious malocclusion needs to be corrected during their growth and development. If it is delayed, it may cause serious facial deformity. In orthodontic treatment, simple removable appliances can be used for local teeth with uneven arrangement; For facial skeletal dysplasia, functional appliances can be used to correct it during its growth and development period, which can achieve good results. Of course, some cases with congenital or genetic factors often need surgical treatment to obviously improve the deformity.
For most malocclusions in which teeth have been replaced, fixed orthodontics (also called "braces") is currently used. Straight wire appliance is the most advanced fixed appliance, which is more efficient than traditional standard edgewise appliance and easier to achieve the best occlusion of teeth. For adults, an increasingly large orthodontic group, as long as the facial bones are not deformed and the health of periodontal tissues is not very bad, most of them can get satisfactory results, but the course of treatment will be slightly longer. In fact, in developed countries, orthodontics for the elderly is also in the ascendant.
