No tie-wings to come into occlusion Ligature wire channel Chamfered tube opening to assist in wire insertion Micro-Etched base with offset option Metal Injection Molded, including integral hook The design of the 3M™ Victory Series™ 2nd Bicuspid Tube eliminates occlusal tie-wings, which can cause occlusal interference and its potential for bond failures. With the use of the tube rather than a slot, the need for ligatures has been eliminated as well. No ligatures means reduced friction on the archwire, providing enhanced posterior sliding mechanics. Together, the design features of Victory Series 2nd Bicuspid Tubes make treatment more efficient and predictable. There are advantages for the patient, too. The smooth radiused design improves patient comfort and facilitates better hygiene.
