Dimensional variability of orthodontic slots and archwires: an analysis of torque expression and clinical implications

ConclusionsDue to production tolerance, differences between the nominal values and the real dimensions of any components of a slot/archwire system are common. This results in a torsional play that limits torque expression. The archwire ’s edge bevel plays an important role in torque expression, and clearer information should be provided by the manufacturers regarding this aspect.
