Product information

Product 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 (see images page).

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..

Field of Application


  • Expansion of skeletally narrow upper jaws


  • Age-dependent, ossified palatal expansion



Removal of the collar

The collar extractor allows the gentle removal of the collar-supported palatal expansion appliances (Geklebe Hybrid- and MICRO4/6-Hyrax). The removal finger reaches under the edge of the collar. After removal of the resin above the screw head, the collar can be pressed from the mini anchor screw using a stylus.
