Fixed appliance treatment is the most precise way to control tooth movement to achieve the perfect smile. There are three main components to such appliances including the brackets (which are attached to the teeth), archwires (the wires placed into the brackets) and auxiliaries such as elastics. The bracket helps to determine the final tooth position. The archwire acts as the motor and places the necessary forces to initiate and sustain tooth movement. The brackets can be made of metal or tooth-coloured ceramic materials.
