A bonded lingual orthodontic retainer is a fixed appliance consisting of a thin metal wire attached to the inner surfaces of the teeth, typically spanning from canine to canine. This retainer plays a crucial role in maintaining the alignment achieved through orthodontic treatment by preventing teeth from shifting back to their original positions. Its fixed nature ensures consistent retention without relying on patient compliance, and its placement on the tongue side of the teeth makes it virtually invisible, preserving the aesthetics of the smile. Proper bonding techniques, such as the indirect bonding method, are essential to ensure accurate positioning and long-term stability of the retainer.
