3M™ Victory Series™ Mini Tubes are designed to address the challenges of bonding to partially erupted second molars. They have a mesially-extended, compound contoured, micro-etched bonding base that allows for superior fit and bond strength. The Mini Tube features a short, low profile hook that enhances patient comfort. The design also incorporates a seating notch to allow easier and more accurate placement of the buccal tube.
Partially erupted second molars may only have a small amount of exposed crown surface for bonding, a less than ideal condition when bonding with traditional direct bond tubes.
