The history of orthodontics has been intimately linked with the history of dentistry for more than 2000 years.

Dental braces
Dental braces (also known as braces, orthodontic cases, or cases) are devices used in orthodontics that align and straighten 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 underbites, as well as malocclusions, overbites, open bites, 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.
Orthodontics
"Orthodontics" is derived from the Greek "orthos" ("correct", "straight") and "-odont-" ("tooth"). The history of orthodontics has been intimately linked with the history of dentistry for more than 2000 years. Dentistry had its origins as a part of medicine. According to the American Association of Orthodontists, archaeologists have discovered mummified ancients with metal bands wrapped around individual teeth. Malocclusion is not a disease, but abnormal alignment of the teeth and the way the upper and lower teeth fit together. The prevalence of malocclusion varies, but using orthodontic treatment indices, which categorize malocclusions in terms of severity, it can be said that nearly 30% of the population present with malocclusions severe enough to benefit from orthodontic treatment.
Lingual braces
Lingual braces are one of the many types of the fixed orthodontic treatment appliances available to patients needing orthodontics. They involve attaching the orthodontic brackets on the inner sides of the teeth. The main advantage of lingual braces is their near invisibility compared to the standard braces, which are attached on the buccal sides of the tooth. Lingual braces were invented by Craven Kurz in 1976. Craven Kurz with Jim Mulick in 1975 developed the Cruz Lingual Appliances in United States. The first patient to be treated by lingual braces was by Dr. Kurz in Beverley Hills in 1976. She was a member of Playboy Bunny Club and after being presented with metal braces option, she wanted to get braces which did not show metal.
List of Madagascar (franchise) characters
This is a list of characters that have appeared in the "Madagascar" films, the television series "The Penguins of Madagascar", and the Netflix series "All Hail King Julien". Tom McGrath explained in an interview that the intention of "Madagascar" was not to take a political stance on whether "zoos are bad and the wild is better, or that the wild is bad," but to show "the most extreme 'fish out of water' story that [they] could do". McGrath stated "the basic irony to the story is that, you think animals do belong in the wild, but if they're so accustomed to civility, they wouldn't know where food even came from," and the animals were meant to "love the zoo and to love where they are because they've got" "right off Fifth Avenue".
Info-gap decision theory
Info-gap decision theory is a non-probabilistic decision theory that seeks to optimize robustness to failure – or opportuneness for windfall – under severe uncertainty, in particular applying sensitivity analysis of the stability radius type to perturbations in the value of a given estimate of the parameter of interest. It has some connections with Wald's maximin model; some authors distinguish them, others consider them instances of the same principle. It has been developed since the 1980s by Yakov Ben-Haim, and has found many applications and described as a theory for decision-making under ""severe" uncertainty".
Orthodontic archwires
An orthodontic archwire 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. Orthodontic archwires may be fabricated from several alloys, most commonly stainless steel, nickel-titanium alloy (NiTi), and beta-titanium alloy (composed primarily of titanium and molybdenum). Nobles metals such as gold, platinum, iridium, silver and their alloys were used early on in the field of Orthodontics because of their good corrosion resistance.
Ravindra Nanda
Dr. Ravindra Nanda (born 19 February 1943) is a professor and Head of the Department of Craniofacial Sciences and Chair of the Division of Orthodontics at the University of Connecticut School of Dental Medicine. He is part of the founding faculty of School of Dental Medicine and has been at the University of Connecticut since 1972 where he also holds an Alumni Chair in the Orthodontics Division. He is an innovator of various appliances in orthodontics. His research and clinical interests include adolescent and adult orthodontics, the biology of tooth mobility, craniofacial orthopedics, biomechanics and developing efficient mechanics to deliver orthodontic care.
