Maxillary deficiency can be transversely extended with removable screw plaques. When providing the removable screw plaques, the patient is instructed how to open them, often once every 5 days. In some cases, Hyrax screws, which are slightly larger, can be used to open the midline gap of the palate, but the type of screw is dependent on the type of malformation. Sometimes the maxilla, in addition to being small, it may be inadequately grown in the anteroposterior direction. In other words, it may be far behind its correct position. This condition requires extraoral appliances which attach to the maxillary removable plaque with elastic bands and guide the maxilla forward.<\/p>\n\n\n\n
The extraoral appliances used for this purpose includes the face mask and reverse chin cup. However, other orthodontic appliances including removable intraoral plaques with rods in the front are able to extend the maxilla. These appliances can be assisted by the tongue force applied to the rods. The tongue can be used to compensate for decreased maxillary growth. Alternatively, the maxillary growth can be increased by placing mini-screws<\/a> or a mini-plate in the mandible along with elastic bands and removable orthodontics<\/a> or fixed orthodontics appliances in the maxilla.

Surgery will be required if the patient refers after puberty.<\/p>\n\n\n \n
