People's dental arch and tooth arrangement have a certain width and radian. If it is less than the normal width, the dental arch is narrow. Dental arch stenosis is generally related to jaw dysplasia, and the probability of occurrence is about 10%. Because of the narrow dental arch, the number of teeth has not decreased, and the teeth can only be squeezed out, resulting in crowded teeth and poor occlusion, which affects the function of chewing hair and sound and facial beauty. Therefore, it is very important to enlarge the arch and correct the dental arch stenosis in time and effectively.
Optimal treatment opportunity
The best time to treat dental arch stenosis is the period of changing teeth in children, usually at the age of 8- 12. Generally speaking, the younger the age, the better the effect of treating dental arch stenosis. If the stenosis is slight, arch expansion can still be performed after 14 years old.
therapeutic method
1. For the treatment of nasal diseases, such as allergic rhinitis, please consult the ENT department so that children can have normal nasal ventilation.
If mouth breathing is caused by tonsil adenoids hypertrophy, then the respiratory tract must be treated first, such as tonsil adenoidectomy.
2. Orthodontic treatment is mainly to expand the arch, which can be achieved in two aspects: one is to increase the width of the jaw, and the other is the buccal displacement of the teeth. There are many ways to expand the arch, and the movable appliance can be used to expand the arch.
If the severity is mild, a mild or moderate arch dilator can be used to expand the width. In severe cases, the alveolar bone can be enlarged by spiral arch expander (rapid arch expander). If it is extremely rare and severe congenital, and the above-mentioned arch expansion effect is not good, surgery is needed.
Children and adolescents with early growth and development can achieve good arch expansion effect by opening the fibrous tissue connection of palatal suture through orthodontic arch expansion.
Teenagers and adults at the late peak of development have fused and ossified the middle palatal seam. Conventional spiral arch expansion can not effectively expand the middle palatal seam, which is mainly made up by dental arch expansion. It is easy to cause the buccal inclination of the upper molar to be too large, leading to periodontal risk, buccal cortical perforation, alveolar bone absorption and other problems. If you want to achieve the effect of bone arch expansion, you need to choose MSE and other methods to deal with it.
Therefore, the treatment of dental arch stenosis should be early!
In order to let the whole society know more about the knowledge about the treatment of dental arch stenosis in children and adolescents, Rebecca, director of Shanghai Stomatological Hospital, and Yu Liming, the attending physician of Orthodontics Department of Shanghai Stomatological Hospital, specially invited the Shanghai Health Public Consultation Service Center to provide the public with advice and guidance on "the timing and methods of treatment of dental arch stenosis in children and adolescents" through online interviews and telephone consultation this afternoon.
