Orthodontic Appliances
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. All these types can be fixed or removable. Active appliances An active appliance is a device used to apply forces to the teeth to change the relationship of the teeth. Removable active appliances Removable active appliances are intended for simple tipping movements. Use of removable appliances in modern orthodontics is much more limited than in the past due to their various shortcomings. * Expansion and labial segment alignment appliance (ELSAA) Fixed active appliances Edward Angle, regarded as the father of American orthodontics, developed many universal fixed active appliances, unifying orthodontic practice. * Begg lightwire applian ...

Dental Technology
A dental technician is a member of the dental team who, upon prescription from a dental clinician, constructs custom-made restorative and dental appliances. There are four major disciplines within dental technology. These are ''fixed prosthesis'' including Crown (dentistry), crowns, bridge (dentistry), bridges and Dental implant, implants; ''removable prosthesis'', including dentures and removable partial dentures; ''maxillofacial prosthesis'', including ocular prosthesis and craniofacial prosthesis; and ''orthodontics and auxiliaries'', including orthodontic technology, orthodontic appliances and mouthguards. The dentist communicates with the dental technician with prescriptions, drawings, and measurements taken from the patient. The most important aspect of this is a Impression (dental), dental impression into which the technician flows a Plaster#In medicine, gypsum dental stone to create a replica of the patient's anatomy known as a dental cast.

Headgear - Vertical Pull
Headgear, headwear, or headdress is any element of clothing which is worn on one's head, including hats, helmets, turbans and many other types. Headgear is worn for many purposes, including protection against the elements, decoration, or for religious or cultural reasons, including social conventions. Purposes Protection or defence Headgear may be worn for protection against cold (such as the Canadian tuque), heat, rain and other precipitation, glare, sunburn, sunstroke, dust, contaminants, etc. Helmets are worn for protection in battle or against impact, for instance when riding bicycles or motor vehicles. Fashion Headgear can be an article of fashion, usually hats, caps or hoods. The formal man's black silk top hat was formerly an indispensable portion of the suit, and women's hats have, over the years, attained a fantastic number of shapes ranging from immense confections to no more than a few bits of cloth and decorations piled on top of the head. Some hats, such as D ... [...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] |
Overbites
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 is it a form of malocclusion. Rather an absent or excess overbite would be a malocclusion. Normal overbite is not measured in exact terms, but as a proportion (approximately 30–50% of the height of the mandibular incisors) and is commonly expressed as a percentage. Other terms confused with "overbite" Overbite is often confused with overjet, which is the distance between the maxillary anterior teeth and the mandibular anterior teeth in the anterior-posterior axis. "Overbite" may also be used commonly to refer to Class II malocclusion or retrognathia, though this usage can be considered incorrect. This is where the mesiobuccal cusp of the maxillary first molar is situated anterior to the buccal groove of the mandibular first molar; in o ...

Human Mandible
In jawed vertebrates, the mandible (from the Latin ''mandibula'', 'for chewing'), lower jaw, or jawbone is a bone that makes up the lowerand typically more mobilecomponent of the mouth (the upper jaw being known as the maxilla). The jawbone is the skull's only movable, posable bone, sharing joints with the cranium's temporal bones. The mandible hosts the lower teeth (their depth delineated by the alveolar process). Many muscles attach to the bone, which also hosts nerves (some connecting to the teeth) and blood vessels. Amongst other functions, the jawbone is essential for chewing food. Owing to the Neolithic advent of agriculture (), human jaws evolved to be smaller. Although it is the strongest bone of the facial skeleton, the mandible tends to deform in old age; it is also subject to fracturing. Surgery allows for the removal of jawbone fragments (or its entirety) as well as regenerative methods. Additionally, the bone is of great forensic significance. Struct ...

Maxilla
In vertebrates, the maxilla (: maxillae ) is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis. The mandible is the movable part of the jaw. Anatomy Structure The maxilla is a paired bone - the two maxillae unite with each other at the intermaxillary suture. The maxilla consists of: * The body of the maxilla: pyramid-shaped; has an orbital, a nasal, an infratemporal, and a facial surface; contains the maxillary sinus. * Four processes: ** the zygomatic process ** the frontal process ** the alveolar process ** the palatine process It has three surfaces: * the anterior, posterior, medial Features of the maxilla include: * t ...

Dental Brace
Dental braces (also known as orthodontic braces, or simply braces) are devices used in orthodontics that align and straighten Human tooth, teeth and help position them with regard to a person's bite, while also aiming to improve dental health. They are often used to correct Malocclusion, underbites, as well as malocclusions, overbites, open bites, gaps, deep bites, cross bites, crooked teeth, and various other flaws of the teeth and jaw. Braces can be either cosmetic or structural. Dental braces are often used in conjunction with other orthodontic appliances to help widen the palate or jaws and to otherwise assist in shaping the teeth and jaws. Braces are an orthodontic device. They are to make the teeth straight, and to correct problems in a person's bite. There are many natural problems which occur to the way teeth fit together, but not everyone needs or will need braces. However, the use of braces is quite common, even when they are not medically necessary. Their cosmetic use f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mouth Breathing
Mouth breathing, medically known as chronic oral ventilation, is long-term breathing through the mouth. It often is caused by an obstruction to breathing through the nose, the innate breathing organ in the human body. However, by the early 20th century, the term "mouth-breather" had developed a pejorative slang meaning connoting a stupid person. Etymology In the early 20th century, "mouth-breather" was a technical term used by doctors to describe children who were breathing through their mouths due to an underlying medical condition. English lexicographer Jonathon Green notes that by 1915, the phrase "mouth-breather" had developed a pejorative connotation within English slang, defined as a "stupid person". Currently, the '' Macmillan Dictionary'' defines the term "mouth breather" as a pejorative noun that is used to mean "a stupid person". Causes Some claim that humans have evolved to breathe through the nose. Infants for example in the first six to twelve months of postna ...

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 derives . 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 malocclusion, then treatment may not be necessary. It is estimated that nearly 30% of the population have malocclusions that are cat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
