Ortho-surgical disjunction of the Palate

Maxillary Expansion

The maxillary expansion can be done basically in four ways:

1. Orthopedic disjunction: this kind of disjunction is performed with a dental appliance in patients under 12 years of age with a better effect in the anterior maxilla.
2. Orthodontic compensation: also done in adult patients with a maximum gain of 1 mm in each region later. There is a higher dentoalveolar inclination and no bone expansion.
3. Orthodontic-Surgical disjunction
4. Surgical disjunction does not involve an apparatus on the palate. It is made exclusively with surgery and is reserved for patients who will undergo another type of surgery in the upper jaw beyond that, but the disjunction must be minimized to prevent recurrences.

 

Ortho-surgical disjunction of the palate

Adult patients with jaw atresia or diminution of the transverse diameter of the upper jaw, should not be treated only with orthodontic disjunction because there will be resistance of the facial skeleton not allowing the palatine bone undergoes expansion. After surgery, the device previously placed is activated fourth round per day and after expansion of the jaw is sealed with resin.
