Abstract
Orthodontic brackets made of a light-transmissive material such as plastic or ceramic have a removable, water-based colorant to facilitate identification of the bracket and alignment of the bracket on the patient's tooth. The colorant is received in a ligature channel of the bracket and is visible through adjacent tiewings of the bracket. The colorant is protected by the overlying tiewings from inadvertent damage or removal as might otherwise occur during initial handling and placement of the bracket.
