Orthodontics is a specialty of dentistry that is responsible for the study, prevention, diagnosis and treatment of abnormalities of shape, position, relationship and function of dentomaxylophial structures.
Orthodontic treatment can be done in two ways depending on the type of forces that are applied and are the following:
The fixed technique by means of fixed apparatus. It is composed of elements attached to the teeth -bands and brackets- to which are firmly anchored thin elastic arches of metal alloy - nickel-titanium - by means of a set of ligatures.
Removable are those that allow to be removed from the mouth by the patient. This allows you to remove them during oral hygiene and meals. These devices, when treating dental problems, have their specific indications that do not replace fixed orthodontics, although they solve some simple malocclusions with a lower economic cost and less discomfort for patients. On the other hand, they are widely used in orthopedics of the maxillae with very diverse results, but always with greater scope of use than the orthodontics multibrackets. They are mainly used as treatment in temporary dentition (early or infantile), where certain pathological states diagnosed in time can be corrected, to such a degree that the treatment in permanent dentition is very specific or even unnecessary.
Patients often need both techniques to solve their dental problems.
A specific type of removable appliances are transparent aligners, which have resulted in a type of treatments that can be referred to as invisible orthodontics, plastic orthodontics, transparent orthodontics or aligner orthodontics.
