Orthodontics [a] [b] is a dentistry specialty that addresses the diagnosis, prevention, management, and correction of mal-positioned teeth and jaws, as well as misaligned bite patterns. [2] It may also address the modification of facial growth, known as dentofacial orthopedics. Abnormal alignment of the teeth and jaws is very common.
Orthodontic technology is a specialty of dental technology that is concerned with the design and fabrication of dental appliances for the treatment of malocclusions, which may be a result of tooth irregularity, disproportionate jaw relationships, or both. There are three main types of orthodontic appliances: active, passive and functional.
This article lists different types of expanders that are available for the process of palatal expansion in the field of orthodontics. [1] [2] 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 ...
A palatal expander is a device in the field of orthodontics which is used to widen the upper jaw [1] so that the bottom and upper teeth will fit together better. [2] [3] This is a common orthodontic procedure. The use of an expander is most common in children and adolescents 8–18 years of age.
Between the two surgeries, a patient's constricted maxillary arch is expanded with the rapid maxillary expander device placed in the maxilla. For the first surgery, under local anaesthesia and iv sedation or general anesthesia , a patient first goes through Le Fort fracture of skull without the downfracture of maxilla.
Frankel appliance or Frankel Functional Regulator is an orthodontic functional appliance which was developed by Rolf Fränkel in 1950s for treatment to patients of all ages (more so for adults In Orthotropics). This appliance primarily focused on the modulation of neuromuscular activity in order to produce changes in jaw and teeth.
Orthognathic surgery (/ ˌ ɔːr θ ə ɡ ˈ n æ θ ɪ k /), also known as corrective jaw surgery or simply jaw surgery, is surgery designed to correct conditions of the jaw and lower face related to structure, growth, airway issues including sleep apnea, TMJ disorders, malocclusion problems primarily arising from skeletal disharmonies, and other orthodontic dental bite problems that cannot ...
Other innovations in orthodontics in the late 19th and early 20th centuries included the first textbook on orthodontics for children, published by J.J. Guilford in 1889, and the use of rubber elastics, pioneered by Calvin S. Case, along with Henry Albert Baker. Today, space age wires (also known as dental arch wires) are used to tighten braces.
