An ingenious alternative to traditional expanders, the Super Screw is a telescoping metal expander that does away with the wire keys used to activate the appliance and replaces it with a small hex wrench, making it more user friendly.
As the screw is activated, a scale is revealed with lines indicating every 2mm of expansion so you can tell at a glance how treatment is progressing. They are available in 18, and 12mm sizes.
