The PowerScrew is a double telescope screw for use in palatal
expansion devices. It is available in five sizes (8mm, 10mm, 12mm, 14mm,
and 16mm installation size).
Activation is simple, the 8cm long flat wrench can be quickly and safely used by the patient on the hexagonal nut.
The
PowerScrew is ideal for narrow palates and can accommodate a growing
palate. By changing the hexagonal nut for the next larger size, the
expander can continue to be used without fabricating a new appliance.
The
PowerScrew’s retention arms are extremely stable and can withstand
significant forces and torques. One turn (6 flat surfaces*) equals 1mm
expansion (0.17mm per flat surface); every second flat surface is marked
with increasing points.
*Contains nickel
