TRANSLUCENT ORTHODONTIC BRACKET WITH VISIBLE MARKERS

摘要

Orthodontic brackets (10) made of a light-transmissive material such as plastic or ceramic have a removable, water-based colorant (32) to facilitate identification of the bracket (10) and alignment of the bracket (10) on the patient's tooth. The colorant (32) is received in a ligature channel (26, 28) of the bracket (10) and is visible through adjacent tiewings (18, 20, 22, 24) of the bracket (10). The colorant (32) is protected by the overlying tiewings (18, 20, 22, 24) from inadvertent damage or removal as might otherwise occur during initial handling and placement of the bracket (10).
