The HILLS Dual-Geometry arch wire is the optimal wire for "Sliding mechanics" and "anterior retraction" while maintaining nearly perfect torque control.
Full sized square anterior section fills the slot for optimal torque control
Round posterior section is polished to minimize friction
  • Square anterior portion ensures full torque control by filling the slot occluso-gingivally.
  • Easy to engage and close the spring due to the reduced labio-lingual dimension.
  • Perfectly round and polished posterior section minimizes friction and cooperates with the spring clip for optimal rotation and tip control during tooth translation.
  • Made of an ultra-high tensile strength stainless steel for optimum stiffness.
  • Available for both the .018” slot and .022” slot in a variety of archform sizes.
