Orthodontics is a science that is responsible for all study, prevention, diagnosis and treatment of anomalies in the shape, position, relationship and function of dentomaxillofacial structures; being its practice the art of preventing, diagnosing and correcting its possible alterations and keeping them in an optimal state of health and harmony, through the use and control of different types of forces.
The fixed technique by fixed appliances that is composed of elements attached to the teeth (bands and brackets) to which are firmly anchored fine elastic arcs of metallic alloy (nickel-titanium) by a set of ligatures.
The removable ones, which can be removed from the mouth by the patient. This allows you to take them off during oral hygiene and at 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 usually widely used in maxillary orthopedics with very different results, but always with a greater scope than multi-brackets orthodontics.
They are used mainly as treatment in temporary dentition (early or childhood), where certain pathological conditions diagnosed in time can be corrected, to such a degree that the treatment in the permanent dentition is very specific or even unnecessary.
In many cases, patients need both techniques to solve their dental problems.
Orthodontics includes the correction of dentofacial irregularities and dental disharmonies to achieve a more favorable aesthetic and functional condition.
The elaboration of the appropriate treatment plan in a case of crowding is done after deciding if the lack of space can be solved, conservatively, increasing the length of the arch or if the case requires extractions.
Lower crowding relapses in most cases, regardless of whether they have been treated with or without extractions. In cases treated without extractions, the lower facial height increases and the tendency to open bite increases.
In cases treated with extractions, the final position of the incisors and the lips is more retruded than the initial one, with which there is a decrease in the convexity of the lower facial third.
