Palatal Orthodontics

A4306.- Palatal Expansion – Orthodontics

With the palatal orthodontics we can correct the bite of growing kids .

Indications and benefits

Rapid palatal expansion is a preliminary treatment procedure that aims at enlarging the maxillary dental arch and the palate (roof of the mouth) to re-establish balance between the width of the jaws. This procedure is also called “maxillary expansion”.
Expansion is indicated when the upper jaw is too narrow compared to the lower jaw. This often causes an abnormal dental relationship and/or deviation of the lower jaw (see pictures).
A jaw that is too narrow can often limit the airway located above the palate (nasal cavity) and expansion may sometimes help this condition. Palatal enlargement can facilitate the flow of air in the nasal cavity and allow the patient to breathe more easily through the nose.
By widening the jaw, expansion may create more space to align crowded teeth.
This procedure can be done at an early age because jaw width problems are visible early and will not be fixed with time.
It is important to note that most of the time, a second phase of treatment will be necessary when all the permanent teeth have erupted to complete the corrections of the malocclusion.
Expansion is not aimed at correcting dental malpositions but only harmonizing the width of the jaws instead. This can sometimes improve the position of the teeth but, sometimes, the position of the upper incisors may seem to be not as good after the expansion. This will be fixed during a second phase of treatment.
Ideally, expansion using an “expander” is performed at an early age (mixed dentition).
