William J. Clark
Dr. William J. Clark is a Scottish orthodontist known for developing Twin Block Appliance in Orthodontics. This appliance was developed by Dr. Clark in 1977 in Scotland and since then this appliance has been used in correction of Class 2 malocclusions with retrognathic mandible. He also developed invisible TransForce Appliance in 2004. Orthodontics Clark is the recipient of the first award for distinction in Orthodontics by British Orthodontic Society. The International Functional Association awarded Clark in 2008 for his contributions to Orthodontics. He published a textbook in 2002 called ''Twin Block Functional Therapy - Applications in Dentofacial Orthopaedics''. Dr. Clark is credited to be the first person part of a teleconference at a dental course in Chicago in 1990 which was eventually transmitted to 25 different cities via satellite.

Dentist
A dentist, also known as a dental surgeon, is a health care professional who specializes in dentistry (the diagnosis, prevention, management, and treatment of diseases and conditions of the mouth, oral cavity and other aspects of the craniofacial complex including the temporomandibular joint). The dentist's Dental auxiliary, supporting team aids in providing oral health services. The dental team includes dental assistants, dental hygienists, dental technicians, and sometimes dental therapists. History Middle Ages In China as well as France, the first people to perform dentistry were barbers. They have been categorized into 2 distinct groups: guild of barbers and lay barbers. The first group, the Guild of Barbers, was created to distinguish more educated and qualified dental surgeons from lay barbers. Guild barbers were trained to do complex surgeries. The second group, the lay barbers, were qualified to perform regular hygienic services such as shaving and tooth extraction as w ...

Orthodontics
Orthodontics is a dentistry specialty that addresses the diagnosis, prevention, management, and correction of mal-positioned teeth and jaws, and 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. Nearly 50% of the developed world's population, according to the American Association of Orthodontics, has malocclusions severe enough to benefit from orthodontic treatment: although this figure decreases to less than 10% according to the same AAO statement when referring to medically necessary orthodontics. However, conclusive scientific evidence for the health benefits of orthodontic treatment is lacking, although patients with completed orthodontic treatment have reported a higher quality of life than that of untreated patients undergoing orthodontic treatment. Treatment may require several months to a few years, and entails using dental braces and other appliances t ...

Twin Block Appliance
A twin block is an orthodontic appliance developed by William J. Clark whose purpose is to lengthen the lower jaw by posturing it forward. If the jaw is growing during treatment, it naturally grows at a faster rate; otherwise the appliance is useless. Treatment time varies, but is generally around 9 months. Twin Blocks can also be used to cure an overbite Overbite is the extent of vertical ( superior-inferior) overlap of the maxillary central incisors over the mandibular central incisors, measured relative to the incisal ridges. The term overbite does not refer to a specific condition, nor i ..., which can mean treatment may be slightly longer. If this is the case, treatment can vary from 6 to 11 months.

Retrognathism
Retrognathia is a type of malocclusion which refers to an abnormal posterior positioning of the maxilla or mandible, particularly the mandible, relative to the facial skeleton and soft tissues. A retrognathic mandible is commonly referred to as an overbite, though this terminology is not used medically. See also * Micrognathism * Prognathism Prognathism, also called Habsburg jaw or Habsburgs' jaw primarily in the context of its prevalence amongst members of the House of Habsburg, is a positional relationship of the mandible or maxilla to the skeletal base where either of the jaws pr ...

Mandible
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower tooth, teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed prenatal development, in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from ''wikt:mandere ...

British Orthodontic Society
The British Orthodontic Society (BOS) is a medical association for orthodontists in England. It publishes the '' Journal of Orthodontics''. The British Orthodontic society represents all orthodontists and dentists carrying out orthodontics across the UK. History The Orthodontic Societies The British Orthodontic Society (BOS) was founded on 1 July 1994. It represented the unification of the five existing UK orthodontic societies: British Society for the Study of Orthodontics (BSSO) Founded in 1907, this was the first national orthodontic society. It had its origins in London, where on 21 October 1907, George Northcroft invited 15 colleagues to discuss establishing a society to promote orthodontics. The inaugural meeting of the BSSO took place on 5 December 1907, when JH Badcock was elected as the Society's first President. Originally conceived as a study group, it became a well respected scientific organisation. For most of its existence, it published the "Transactions of ...

Malocclusion
In orthodontics, a malocclusion is a misalignment or incorrect relation between the teeth of the upper and lower dental arches when they approach each other as the jaws close. The English-language term dates from 1864; Edward Angle (1855-1930), the "father of modern orthodontics", popularised it. The word "malocclusion" derives from ''occlusion'', and refers to the manner in which opposing teeth meet ('' mal-'' + ''occlusion'' = "incorrect closure"). The malocclusion classification is based on the relationship of the mesiobuccal cusp of the maxillary first molar and the buccal groove of the mandibular first molar. If this molar relationship exists, then the teeth can align into normal occlusion. According to Angle, malocclusion is any deviation of the occlusion from the ideal. However, assessment for malocclusion should also take into account aesthetics and the impact on functionality. If these aspects are acceptable to the patient despite meeting the formal definition of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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]   |
