3M Unitek T Spring for Ligature Wire Attachment
An orthodontic T spring with a mesial loop built in for attaching ligature wire, used as an auxiliary in fixed appliance mechanics.
The 3M Unitek T Spring is a small orthodontic auxiliary shaped to incorporate a mesial loop, giving the clinician a defined point to attach ligature wire during treatment. Orthodontists use springs of this type to apply targeted, sustained force to an individual tooth or short segment of the arch, often to correct positioning issues that general archwire mechanics cannot address on their own.
The mesial loop design makes it straightforward to tie the spring into place alongside the existing archwire and bracket system without needing extra hardware. As with other items in the Unitek Springs and Push Rods range, the T Spring is a disposable consumable that practices order in quantity rather than a reusable instrument.
It is available in two arbor diameter measurements, so clinicians can choose the size that best suits the archwire and bracket combination in use.
