It was credited to physician Pierre Fauchard (regarded as father of dentistry) at the start of 18th century in France who described an appliance called as â€Å"Bandlette† (now known as expansion arch (Graber TM 1966, cited in Vijayalakshmi & Veereshi 2010, p. 11). He was the first to attempt moving the teeth using Bandlette, an arched flat strip of metal with holes for threads to pass through and apply force upon the teeth. The first fixed appliance used in orthodontics is attributed to Pierre Fauchard while the first removable appliance recognized in orthodontic practice was the Coffin plate introduced by Coffin during the late 19th century (Vijayalakshmi & Veereshi 2010). The Coffin plate had a spring (still present in the current appliances) made of piano wire (Proffit & Fields 1999; Graber N 1977, cited in Vijayalakshmi & Veereshi 2010). The fixed or removable appliance adjusts the teeth slowly and cautiously to prevent extreme pain and damage to the teeth (Cunningham, Ho rrocks, Hunt, et al. 2000).

There is also a tendency for malocclusion to recur, he added. Malocclusion refers to the atypical arrangement of the teeth or jaws (Cunningham, Horrocks, Hunt, et al. 2000). Malocclusion should be treated because it may lead to diseases, cause dysfunction of the jaw (that affects speech and mastication, or leads to Tempero-Mandibular Disorder), affects aesthetic features of the face that may have negative psychological implication, and damage to teeth (Mascia n.d.).
