How does it work?

There are two types of appliances: fixed or removable and they aplly small forces on the teeth and jaws.
Braces consist of bands, brackets and arch wire. The bands are placed around a tooth / teeth and serve to anchor the brackets are glued on the front of the teeth and arches of wire passing through bracketts and bind to the bands. The tightness of the wire increases the tension on the teeth causing teeth to move to their proper position and shall be adjusted monthly. The duration of treatment depends on each case is normally 2-3 years.

Maxillary expansion

Patients who suffer from cross bite can be treated using a palate expander - quadhelix. The device is placed on the back teeth of the upper jaw, pushing them out gently expanding the upper jaw until it reached the desired width.

Rapid maxillary expansion

Outra forma de tratar as mordidas cruzadas é através de um aparelho expansor rápido. O aparelho é colocado nos dentes posteriores e vai sendo alargado através do parafuso que tem no meio até que se atinja a largura pretendida. Nota-se um espaço entre os incisivos centrais que depois vai desaparecer com o aparelho fixo.

Ortocirurgic palate disjunction

n patients older than 14 years it is not possible to expand the jaw with only these devices.
 

 

Traction of impacted teeth

The most common are the upper canines and lateral incisors. Impacted teeth, whenever possible, should be relocated and may be drawn in the dental arch. The procedure includes surgical intervention with bracket on the face of the impacted tooth and its traction for braces previously placed particular APA (armillary palatal arch). See impacted teeth surgery

 

Mandibular Advancement

Class II can be treated with a Herbst appliance or similar. The device is placed in the upper and lower teeth with a slide bar to join. The device forces the lower jaw forward training the muscles for this position and stimulating the growth of the mandible.

In the treatment of Class II, elastics also may be used to pull the jaw forward.

 

Correction of the midline

In some cases the midline of the upper teeth do not coincide with the midline of the lower teeth. Placing a rubber band at certain points of the braces will correct this misalignment.

Microimplant

When theres a missing tooth, the opponent tooth can overerupt leaving no room for rehabilitation (in an implant, eg). To pull the teeth up is necessary an anchor point that is achieved with micro-implant placement.

The microimplants can also be used as an anchor to pull a tooth that has moved forward occupying an area of a missing tooth.

 

Closure of open bite

The grid of the tongue is a mechanical barrier that not only prevents the sucking of the finger, but also keeps the tongue in a more retruded position, not allowing its interposition between the incisors during swallowing and speech. With the removal of habit occurs the vertical extrusion of lower incisors and dentoalveolar closing the bite.

 

Lack of space

Sometimes in cases of mild crowding may be necessary to remove a thin layer of enamel in different teeth in order to have space for proper tooth alignment. This can be done with a drill or abrasive paper (stripping).

In situations of crowding the treatment plan is usually the extraction of four premolars (1st premolars s). After the fixed appliance pulls the teeth into place.

Opening Spaces

To restore a missing tooth when there's not enough space to place an implant (because over the time the remaining teeth moved). A fixed appliance straighten your teeth and creates space for rehabilitation after implantation.
