3M Unitek Action Line Thread for Tooth Movement
An elastomeric thread used for rotating and extruding teeth, closing minor spaces and other general intraoral applications during active treatment.
Unitek Action Line Thread is a thin elastomeric thread used across a range of light force applications in orthodontic treatment, including rotating an individual tooth into better alignment, extruding a tooth that needs to be brought further into occlusion, and closing minor residual spaces left along the arch as treatment nears its finishing stages.
Its flexible, thread-like form lets the clinician wrap or tie it in configurations that would not be practical with a rigid wire or a bulkier elastomeric chain, giving more precise control over exactly where and how the light force is applied to a specific tooth or small group of teeth. Because the movements it is used for tend to be finer, more targeted corrections rather than large scale tooth movement, Action Line Thread is typically reached for during the later, detailing stages of treatment when the clinician is refining individual tooth positions rather than during the initial leveling and alignment phase.
It is supplied under three catalog numbers, reflecting different thread gauges or spool lengths available. Practices doing detailed finishing work with fixed appliances keep this thread stocked as a versatile, low-cost auxiliary for the range of minor intraoral corrections it supports.
