Orthodontics is a field in dentistry which aims to straighten or align teeth and correct skeletal discrepancies. The orthodontic treatment has two main goals: Improvement of the dental aesthetics and masticatory function.

However, orthodontic treatment improves the smile, the harmony of the face, the respiration, the craniofacial growth, the speech, and the swallowing pattern of the patient.
Another goal of the orthodontic treatment is to facilitate the dental hygiene thanks to the correct alignment of the teeth and its prevention of periodontal diseases and gingivitis.
