Description

The PowerScrew is a double telescope screw for use in palatal expansion devices. It is available in three sizes (8, 12 and 16 mm installation size). Activation is simple, as the 8 cm long flat spanner can be quickly and safely used by the patient on the hexagonal screw.
Narrow palates need a small expansion screw. The PowerScrew therefore grows with it. By simply changing the hexagonal screw for the next biggest, the expander can continue to be used without making a new one.
The PowerScrew and its retention arms are extremely stable and can withstand the greatest forces and torques. One turn (6 surfaces) equals 1 mm expansion (0.17 mm per surface); every second surface is marked with increasing points.
