Tornillos de expansión

Palatal expansion screws for widening the upper arch, including Hyrax, Bertoni and mini expanders in straight, angled and single tooth designs. Expansion corrects posterior crossbites and creates space in narrow arches, particularly in growing patients.

Hyrax type screws are soldered or welded to bands and give rapid, controlled expansion. Mini screws suit smaller palates and removable appliances, and single tooth screws move individual teeth.

Choose the screw by the amount of expansion needed and the space available in the palate, and give the patient clear activation instructions.
