These are treatments aimed at guiding the development of the jaw correctly and arranging the alignment of the teeth in cases that occur or are likely to occur during the development of teeth and jaws. This treatment consists of special materials attached to each tooth and wires for force application, and usually covers a treatment period of 12-18 months. Recently, classical orthodontic treatment applications can be applied in the form of alternative methods such as producing these retainers from porcelain material for a more aesthetic appearance, attaching the retainers to the invisible surface of the tooth (lingual orthodontics), and especially recently, applying force through transparent plaques.
