3M Unitek Gurin Lock for Coil Spring Activation
An adjustable orthodontic lock used as a stop or tie back point, or to activate coil springs when opening or closing spaces along the archwire.
The 3M Unitek Gurin Lock is a small, adjustable orthodontic component with several roles in fixed appliance treatment. Orthodontists use it as an adjustable stop or tie back stop along the archwire, and also as a means of activating coil springs when a treatment plan calls for opening or closing spaces between teeth.
Because it is adjustable rather than fixed, the clinician can reposition it during a visit as the case progresses, rather than replacing the whole auxiliary each time. It belongs to the Gurin family of orthodontic hooks and stops, which is designed to work as a coordinated system alongside Gurin nuts and the matching wrench for tightening.
This listing is supplied under three catalog numbers, likely reflecting different sizes or configurations of the same lock, and is intended as a stocked consumable for practices running active orthodontic cases rather than a single-use fitting.
