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]
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.
A study published by Martina et al. [10] stated that rapid maxillary expansion is not more effective than slow maxillary expansion in expanding the maxilla in patients with posterior crossbite. It is important to keep in mind that different studies use different rapid and slow expansion devices and thus comparability between studies is difficult.
The second category uses the principles of osteodistraction and osteotomies to facilitate correction of often severe malocclusions, such as rapid maxillary expansion to correct a narrow maxilla or closure of large clefts in cleft palate patients. [9]
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 ]
Expansion of the cyst causes erosion of the floor of the maxillary sinus. As soon as it enters the maxillary antrum, the expansion rate increases due to available space for expansion. Performing a percussion test by tapping the affected teeth will cause shooting pain. This is often clinically diagnostic of pulpal infection. [citation needed]
Orthodontic treatment to expand the volume of the nasal airway, such as nonsurgical Rapid Palatal expansion is common in children. [ 21 ] [ 17 ] Due to the ossification of the median palatine suture, traditional tooth-born expanders cannot achieve maxillary expansion in adults as the mechanical forces instead tip the teeth and dental alveoli.
