Orthodontic science, with the help of direct forces on teeth, is an attempt to better gnaw and protect teeth from wounds and injuries during normal everyday activities (such as the stress that enters into teeth while chewing). Correcting the position of the teeth can reduce the stress on the bones, root tissue, gums, and temporomandibular joint discomfort. This treatment also eliminates dental problems in older people leading to abnormal caries and facilitates proper oral and dental health in order to reduce caries and dental problems in the future. In addition, orthodontic science produces a pleasant smile that ultimately strengthens self-esteem.

The main goals of orthodontic treatment are as follows:

1. Beauty of teeth and face
2. Arranging the teeth to prevent the growth and development of the oral and facial tissues.
3. Prevent over-covering of teeth that ultimately pressure the temporomandibular region and causes pain in the temporal joint region.
4-Holoflaxing of hairs that unpleasantly teeth into soft tissues.
5. Arranging protruding teeth that cause damage and fractures.
6. Tooth brushing to use in teeth and teeth.
7. Sorting the teeth that have been analyzed for gingivitis to spline and keep them stable.
8. Regularizing and balancing teeth and jaws before orthosclerotic treatments
9-To help the eruption of impacted teeth.
