Rounded-Shape Corners for improved patient comfort. The corners and ligating mechanism feature the same buccal curvature as the bracket body. Nitinol Ligating Mechanism features elasticity and high resistance to fatigue during treatment, Easy Ligation with enough space under the tie-wing area for conventional or chain elastics if needed. Integral Hook with simple versatile design. 80 Gauge Mesh Base for better adhesive coverage to increase bonding retention. Torque in Base for precision, control, and easy bracket positioning. Compound Curvature Base allowing for accurate bracket fit. The passive bracket closing mechanism does not touch the ground and rectangular archwire for reduced friction. Door design with an incisal / occlusal opening system promotes efficient ligation because the ligating mechanism does not open spontaneously during treatment. Nitinol ligating mechanism has a high resistance to fatigue during the opening and closing of the ligating mechanism to maintain product integrity during treatment. Because the bracket design allows for ligation, the bracket can be active or passive depending on treatment needs. The rhomboid shape provides a reference for efficient bracket positioning.
