i-arch is a unique and innovative orthodontic system.
Archwires made of a special alloy allow for a highly innovative orthodontic biomechanical approach and are characterized by effectiveness, simplicity, complementarity and biological compatibility.
Efficiency comes from the use of rectangular arches, which ensure instantaneous torque delivery from the leveling and alignment stage.
Simplicity is ensured by the reduced number of arches – only three.
Complementarity results from the possibility of using i-arch with any straight wire technique – with self-ligating brackets .018 or .022 or classic ones. When using classic .022 brackets, it is recommended to use metal ligatures at the beginning of treatment.
Biocompatibility is ensured by the application of very gentle forces (from 40 g) to tooth movement, reducing traumatic effects – especially at the beginning of orthodontic treatment.
The following arch sequence is used in the i-arch system:
- Thermal i-arch .016 x .014, copper-nickel-titanium first arch for alignment, leveling and torqueing;
- Super elastic i-arch, nickel-titanium with a cross-section of .018 × .014 as a second arch for arch shape and sliding mechanics;
- Beta-titanium i-arch with a cross-section of .016 × .016 as the final archwire to achieve arch form, perform intermaxillary mechanics and stabilize treatment results.
The i-arch system offers the following benefits:
- Immediate delivery of torque, which allows for shortened treatment time and effective 3D tooth movement from the beginning of therapy;
- Effectiveness in obtaining arch enlargement;
- Reducing the patient’s pain;
- Reduction of bone damage, especially at the level of the vestibular cortical bone;
- An easy clinical protocol that results in less chair time and requires fewer archwires in practice.
