3M Unitek Action Line Tubing, Hollow for Ligature Knots
Hollow tubing used together with Action Line Thread, helping the clinician tie tighter, more secure knots during orthodontic tooth movement procedures.
Unitek Action Line Tubing is a small piece of hollow tubing intended to be used together with the matching Action Line Thread, giving the clinician a means to create tighter, more secure knots when tying the thread as part of orthodontic mechanics such as tooth rotation, extrusion or minor space closure.
Threading the elastomeric material through a length of tubing before tying helps concentrate and secure the knot more effectively than tying the thread alone, reducing the chance of the tie slipping or loosening prematurely once placed intraorally under normal function and saliva exposure. A secure, well formed knot matters for these finer, more targeted movements because the applied force needs to be maintained consistently between adjustment visits for the intended correction to progress as planned.
This tubing is supplied under three catalog numbers, reflecting different tubing diameters or lengths matched to the range of Action Line Thread gauges available. Practices using Action Line Thread for detailing and finishing work in orthodontic treatment keep a stock of the matching tubing on hand, since the two products are designed to be used together as a system rather than as separate, unrelated items.
