It refers to a device made of a metal or ceramic material fixed on the tooth surface with a special adhesive in orthodontic treatment, which is used to hold and fix the orthodontic wire, transfer the orthodontic force to the teeth, so as to achieve the purpose of tooth correction. Orthodontic brackets are an integral part of traditional braces and act like handles that hold the arch wires that move teeth. The small squares are typically bonded directly to the front of each tooth and come in a variety of styles and sizes, including self-ligating, lingual and titanium. It is useful for a clinician to know the best adhesive for fixing orthodontic brackets, so they do not fail during treatment. Bracket failure increases the time spent in surgery for repairs and the overall treatment time. At present orthodontics can choose between four groups of adhesives which may be set with a chemical reaction or curing light. Some adhesives may prevent early decay around brackets because they contain fluoride.
