At present, many people do not have a special understanding of orthodontics and believe that orthodontics is only for children and teenagers and that adults cannot undergo orthodontic treatment. The principle of orthodontics is that by wearing aligners, a moderate and controlled force is applied to the teeth, alveolar bone and jawbone to produce movement of the teeth, and the teeth can grow firmly in their new position after the movement, thus rearranging them. Orthodontics is not really scary at all, it is in line with the growth pattern of teeth. Just because an adult’s growth spurt is over does not mean that it is necessarily past the optimal orthodontic period. In modern orthodontic treatment, adults have become a large group for orthodontic treatment. Although the external morphology of the bone has been stabilized, the internal regeneration and reconstruction ability of the bone still exists (such as healing after a fracture), and generally speaking, adults can have their teeth straightened if they do not have serious periodontal inflammation. For 60-year-old adults and 12-year-old children, there is not much difference in the effect of orthodontic force on the movement of healthy teeth. The number of adult orthodontists in Europe and the United States accounts for more than 1/3 of orthodontic patients, of whom the oldest orthodontic patient is 81 years old, and there are more 50-60 years old. However, due to the unique physical condition of adults, orthodontics uses strict principles of design, such as small-scale tooth movement, consideration of the posterior bite relationship, and evaluation and balance of aesthetics and function, all of which are different from treatment in childhood. When you are considering orthodontic treatment, you should have an examination and evaluation by a professional orthodontist. For college students, the college stage is a transitional stage for college students to enter the society, their physiology and psychology will enter a mature period, and they can fully feel the negative impact of malocclusion on their entry into the society. After graduating from university, college students will enter a new social environment, and a good appearance will greatly increase their leverage in employment, life, marriage and other aspects, and lay a good start for their life planning. During the summer vacation, college students have a loose schedule and are not under much pressure to study, so they can spend the orthodontic adjustment period more easily and minimize the impact of the aligners on themselves. Also upcoming for some student patients who need orthognathic surgery, inpatient surgery and post-operative recovery takes about 1 month, if you use the summer to do it, it will not affect your homework and it also well protects the privacy of having had the surgery. Therefore, adults can also be orthodontic, although it should be especially emphasized that orthodontic treatment may also be more difficult for those who are older, and that adults who already have skeletal deformities of the jaw and face can only be solved by surgical procedures, and orthodontics alone can only solve their dental problems. Although orthodontic treatment in China started late, but the development is fast, and the country is currently implementing the orthodontist admission system to regulate the current more chaotic orthodontic treatment situation, which may be a blessing for the majority of orthodontic patients. Finally, we wish all adult patients good orthodontic treatment and regain a healthy and bright smile.
