These appliances can be used to achieve expansion in the maxillary arch; there are devices for mandibular expansion or lower expansion too. In past many years, different types of appliances have been made. These types are: tissue-borne, tooth-borne, slow maxillary expansion, rapid maxillary expansion, and bone-anchored.
Rapid palatal expansion (RPE) or Rapid Maxillary Expansion (RME) is an expansion technique where expansion of 0.5 mm to 1 mm is achieved each day until the posterior crossbite is relieved. The expander works by turning a key inside the center of the expander. The turn of this key will push the arms of the expander.
Emerson Colon Angell (1822–1903) was an American dentist who is known as the father of the rapid maxillary expansion. [1] He published a paper in Dental Cosmos in 1860 in which he described this technique. [2] [3]
SARPE is performed to address the transverse dimension changes in a patient. Sometimes this surgery is followed by Le Fort 1 in a second surgery to address the vertical and the anterior-posterior changes. Between the two surgeries, a patient's constricted maxillary arch is expanded with the rapid maxillary expander device placed in the maxilla.
Fan rapid palatal expander in cleft palate prior to alveolar cleft grafting In cleft lip and palate cases, the maxilla is typically narrow compared to the lower jaw and must be expanded outward. An expansion appliance is placed in the maxilla 6–9 months prior to correct any crossbite or upper arch constriction. [ 3 ]
However, many other studies have showed that TPA cannot provide absolute anchorage to prevent mesial movement of the posterior molars. Baccetti et al. (2011) showed that the TPA could be used in the absence of Rapid Maxillary Expander. In these cases, the patients have palatally displaced canine teeth which do not require expansion. [3]
