Fixed braces are the type of braces which cannot be removed by the patient, for eating or other purposes. These braces remain attached to the teeth. They comprise square brackets that are attached to every tooth and a wire runs through them. The purpose of these braces is to gradually moves and align the teeth into the correct position. The wire is fixed in a place using small elastic loops called modules. They can be of different types, including metal, ceramic, lingual and others. The metal braces are traditional braces that are most commonly seen. It consists of metal brackets bonded to the front of the teeth and joined with fine metal wires. The ceramic braces offer a more natural appearance as the ceramic merges with the colour of the teeth. Lingual braces are the type of braces that are worn behind the teeth, on the inside and not the front part. The offer the advantage of not being invisible to others, but they can be difficult to wear. The aim of this orthodontic treatment is to improve the overall appearance and functionality of the teeth. The braces can be used to treat conditions such as the crooked or crowded teeth, under bites or overbites, and gaps between teeth.
