Orthodontic headgear is a type of appliance attached to dental braces that aids in correcting more severe bite problems. Headgear is an orthodontic appliance for the correction of Class II correction, typically used in growing patients to correct overbites by holding back the growth of the upper jaw, allowing the lower jaw to catch up.
The headgear attaches to the braces via metal hooks or a facebow. Straps or a head cap anchor the headgear to the back of the head or neck. In some situations, both are used. Elastic bands are used to apply pressure to the bow or hooks. Its purpose is to slow or stop the upper jaw from growing, thereby preventing or correcting an overjet.
Traditional metal wired braces (also known as "train track braces") are stainless-steel and are sometimes used in combination with titanium. Traditional metal braces are the most common type of braces. These braces have a metal bracket with elastic ties (also known as rubber bands) holding the wire onto the metal brackets. The second-most ...
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 ...
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.
He was also one of the first people to report lowering of mandible with bite opening and increase in nasal width and gain in arch perimeter. Robert M. Ricketts introduced the Quad Helix in 1975 which was a modification of the W Spring. Biederman introduced the tooth-borne Hyrax Expander in 1968. Cohen and Silverman were first ones to introduce ...
They can be used for many different reasons, such as Class 2 malocclusions, to reinforce anchorage in a case where an extraction has been done, to allow the maxillary incisors to move backwards, and to correct midline deviation and allow buccal movement of backward-tipped lower incisors. Orthodontists generally use 12-16 oz elastics (3/16") in ...
Intercuspal Position (ICP), also known as Habitual Bite, Habitual Position or Bite of Convenience, is defined at the position where the maxillary and mandibular teeth fit together in maximum interdigitation. This position is usually the most easily recorded and is almost always the occlusion the patient closes into when they are asked to 'bite ...
