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.
Surgically assisted rapid palatal expansion (SARPE), also known as surgically assisted rapid maxillary expansion (SARME), [1] is a technique in the field of orthodontics which is used to expand the maxillary arch. This technique is a combination of both Oral and Maxillofacial Surgery and Orthodontics.
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.
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]
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]
