ARTHUR HALL ORTHODONTICS<br />

Unique Interactive technology enables you to maintain<br />

precise control during each phase <strong>of</strong> treatment.<br />

PASSIVE<br />

Passive function is achieved with<br />

round nickel titanium wires which<br />

slide freely for efficient leveling and<br />

alignment.<br />

EXPRESSIVE<br />

Expressive function is where control<br />

is realised and free sliding is<br />

maintained. This is created with the<br />

light seating <strong>of</strong> a working wire into<br />

the base <strong>of</strong> the slot so programming<br />

may be expressed and rotations<br />

corrected.<br />
