Orthodontic indices are one of the tools that are available for orthodontists to grade and assess malocclusion. [1] Orthodontic indices can be useful for an ...
Translation Translation occurs in the upper TMJ compartment and provides most of the mandible's ability to open. Articular disc and condyle complex slide inferiorly on the articular eminences, allowing maximum depression of the mandible. [7] Maximal Mandibular Opening (T). Condylar heads are said to be at a maximum anterior-inferior position.
An archwire in orthodontics is a wire conforming to the alveolar or dental arch that can be used with dental braces as a source of force in correcting irregularities in the position of the teeth. An archwire can also be used to maintain existing dental positions; in this case it has a retentive purpose.
Little's Irregularity Index is an index used in the field of Orthodontics to measure the crowding of Mandibular anterior arch. The index was first proposed by Robert M. Little in 1975 in his paper The Irregularity Index: A quantitative score of mandibular anterior alignment.
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; [ 1 ] Edward Angle (1855–1930), the "father of modern orthodontics", [ 2 ] [ 3 ] [ need quotation to verify ] popularised it.
Intrusion is a movement in the field of orthodontics where a tooth is moved partially into the bone. Intrusion is done in orthodontics to correct an anterior deep bite or in some cases intrusion of the over-erupted posterior teeth with no opposing tooth. [1] Intrusion can be done in many ways and consists of many different types.
Dr. Robert M. Ricketts (May 5, 1920 – June 17, 2003) was an American orthodontist known for many contributions in the field of orthodontics. [1] Most important contributions were related to his development of Ricketts' Cephalometric Analysis [2] and an .018-inch slot in an orthodontic bracket. His research focused on the growth and structural ...
Cephalometric analysis is the clinical application of cephalometry.It is analysis of the dental and skeletal relationships of a human skull. [1] It is frequently used by dentists, orthodontists, and oral and maxillofacial surgeons as a treatment planning tool. [2]
