3M Unitek Nitinol Heat-Activated Orthodontic Archwire
A thermally activated, super-elastic nitinol orthodontic archwire that is easy to engage and delivers light, continuous forces to move teeth effectively.
3M Unitek Nitinol Heat-Activated Archwire is a super-elastic orthodontic archwire that becomes active at body temperature, engaging automatically once placed in the patient's mouth and warmed to intraoral temperature. The manufacturer describes it as the easiest of the Nitinol wires to engage into brackets, an important practical consideration during a busy orthodontic appointment where wire changes need to be efficient.
Once in place, the wire delivers light, continuous forces on the teeth, a characteristic that is generally considered more comfortable for the patient and more biologically favourable for tooth movement than the heavier, less consistent forces some other wire types can produce. Heat-activated Nitinol archwires like this one are typically used in the earlier stages of fixed appliance treatment, where initial alignment of crowded or rotated teeth calls for gentle, sustained force rather than the stiffer working wires used later in treatment.
The product is listed as transitioning from 3M Unitek to the Solventum brand name.
