Adult orthodontics has many particularities, because adults face problems that children and adolescents rarely face, such as work, job hunting, interview, communication and negotiation. Therefore, there are many special requirements to be solved in adult correction. Specifically, there are the following aspects:

1, the physical condition is complicated.

Adult orthodontics is more complicated than that of children, and adult malocclusion is often accompanied by other oral diseases. Such as dental caries, periodontal disease, tooth loss, tooth wear, residual crown and roots, poor oral cavity repair, temporomandibular joint diseases and so on.

Before starting orthodontic treatment, periodontal disease of teeth must be thoroughly controlled, and the dental prosthesis should be taken out, otherwise it will affect the wearing of the appliance and the movement of teeth. Adults should undergo orthodontic treatment under good oral hygiene conditions, and pay attention to the changes of periodontal conditions during the treatment.

In addition, adult orthodontics should also consider the influence of general health. People suffering from rheumatic heart disease, coronary heart disease, hypothyroidism, hyperacidity, diabetes, arthritis, hemorrhagic diseases, epilepsy and other diseases must first control these diseases. Pregnant women should be cautious in orthodontics.

2, the treatment time is longer.

Because the growth and development of adults have been basically completed, the maxillofacial suture has become bony fusion, with low plasticity, slow metabolism and reduced biological reactivity of adults. Therefore, the alveolar bone remodeling is slow, and the tooth movement is also slow, which requires a long treatment time. Therefore, adult orthodontic treatment should not be hasty, but should be gradual. If we insist on shortening the time, it will bring bad consequences. Children's orthodontics generally takes about one year, and adults' orthodontics generally takes about two years.

3. Different psychological states

Due to the influence of occupation, work and social activities, adults have more requirements for the length of orthodontic treatment, the beauty of orthodontic appliances and the therapeutic effect. Adults have the ability to think independently, and often compare and consider the opinions of friends or family members with the experiences of other orthodontic patients.
