Palatal Expansion
A palatal expander is a device in the field of orthodontics which is used to widen the upper jaw (maxilla) so that the bottom and upper teeth will fit together better. This is a common orthodontic procedure. The use of an expander is most common in children and adolescents 8–18 years of age. It can also be used in adults, although expansion is more uncomfortable and takes longer in adults. A patient who would rather not wait several months for the end result achieved by a palatal expander may be able to opt for a surgical separation of the maxilla. Use of a palatal expander is most often followed by dental braces, braces to then straighten the teeth. Palate expanders are a useful tool in expanding the airway due to previous dental extractions. It is believed that expansion therapy should be started in patients either before or during their peak growth spurt. To obtain maximal skeletal changes, the therapy is typically initiated at a very early age. Expansion therapy performed af ...

Orthodontics
Orthodontics (also referred to as orthodontia) is a dentistry specialty that addresses the diagnosis, prevention, management, and correction of mal-positioned teeth and jaws, as well as misaligned bite patterns. It may also address the modification of facial growth, known as dentofacial orthopedics. Abnormal alignment of the teeth and jaws is very common. The approximate worldwide prevalence of malocclusion was as high as 56%. However, conclusive evidence-based medicine, scientific evidence for the Health benefit (medicine), health benefits of orthodontic treatment is lacking, although patients with completed treatment have reported a higher quality of life than that of untreated patients undergoing orthodontic treatment. The main reason for the prevalence of these malocclusions is diets with less fresh fruit and vegetables and overall softer foods in childhood, causing smaller jaws with less room for the teeth to erupt. Treatment may require several months to a few years and enta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Palatal Expanders
This article lists different types of expanders that are available for the process of palatal expansion in the field of orthodontics. There can be many types of transverse dimension appliances. 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. Types of expanders Tissue-borne expander Tissue supported expanders allow the forces to be applied directly to the tissues of palatal mucosa instead of teeth. The most common type of tissue-borne expander is known as the Haas Appliance. This appliance was popularized by Andrew Haas in 1961. This appliance involves bands placed on maxillary first premolar and first molars on each side. Haas appliance has palatal acrylic that is in contact with palatal mucosa. Inside th ...

List Of Orthodontic Functional Appliances
This is a comprehensive list of functional appliances that are used in the field of orthodontics. The functional appliances can be divided into fixed and removable. The fixed functional appliances have to be bonded to the teeth by an orthodontist. A removable functional appliance does not need to be bonded on the teeth and can be removed by the patient. A removable appliance is usually used by patients who have high degree of compliance with their orthodontic treatment. Fixed appliances are able to produce very accurate movement in the teeth Both fixed and removable functional appliances can be used to correct a malocclusion in three planes: Anterior-Posterior, Vertical and Transverse. In the Anterior-Posterior dimension, appliances such as Class II and Class III are used. Appliances used in transverse dimension are utilized to expand either the maxillary or the mandibular arch. Appliances used in the vertical dimension are used to correct open or deep bite. History It is impo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyrax Expander
Hyraxes (), also called dassies, are small, stout, thickset, herbivorous mammals in the family Procaviidae within the order Hyracoidea. Hyraxes are well-furred, rotund animals with short tails. Modern hyraxes are typically between in length and weigh between . They are superficially similar to marmots or over-large pikas but are much more closely related to elephants and sirenians. Hyraxes have a life span of 9 to 14 years. Both types of "rock" hyrax ( ''P. capensis'' and ''H. brucei'') live on rock outcrops, including cliffs in Ethiopia and isolated granite outcrops called koppies in southern Africa. Almost all hyraxes are limited to Africa; the exception is the rock hyrax (''P. capensis'') which is also found in adjacent parts of the Middle East. Hyraxes were a much more diverse group in the past encompassing species considerably larger than modern hyraxes. The largest known extinct hyrax, '' Titanohyrax ultimus'', has been estimated to weigh , comparabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quad Helix
A quad helix (or quadhelix) is an orthodontic appliance for the upper teeth that is cemented in the mouth. It is attached to the molars by 2 bands and has two or four active helix A helix (; ) is a shape like a cylindrical coil spring or the thread of a machine screw. It is a type of smooth space curve with tangent lines at a constant angle to a fixed axis. Helices are important in biology, as the DNA molecule is for ... springs that widen the arch of the mouth to make room for crowded teeth, or correct a posterior cross-bite, where lower teeth are buccal (outer) than upper teeth. It is usually made from 38 mil stainless steel wire and is primarily indicated in mixed dentition, cleft patients and those that have performed the act of thumbsucking. A variety of this appliance is inserted into attachments that are welded to the bands. In this way the orthodontist can adjust the appliance without removing the bands. The precursor to the quad-helix was the coffin spring. Simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Dental Association
The American Dental Association (ADA) is an American professional dental association. Established in 1859 and with over 159,000 current members, ADA is the world's largest and oldest national dental association. The organization lobbies on behalf of the American dental profession and provides dental accreditation. The ADA publishes the '' Journal of the American Dental Association'' and ''JADA Foundational Science''. As part of its lobbying efforts, the ADA has sought to restrict non-dentists (such as dental hygienists and dental therapists) from providing basic dental care. The organization has played an important role in blocking the inclusion of dental coverage in Medicare. The ADA has expressed opposition to the opening of new dental schools or to increasing the number of dentists in the United States, even as the United States trains almost half as many dental students (relative to population) in the 2000s as it did in the 1980s.
