Hills Dual-Geometry Wire for Posterior Translation
Intended specifically for posterior translation, this design features a slightly larger round posterior diameter. This larger posterior cross-section enhances rotational control and facilitates precise alignment of the roots during tooth translation.

Hills Dual-Geometry Wire for Anterior Retraction
Intended specifically for anterior retraction, this design features a slightly undersized round posterior diameter. This reduced posterior cross-section permits free sliding of the archwire through the posterior attachments during anterior retraction.
