These appliances are commonly used to correct crossbites or make space and have several designs;

Quad helix

This appliance is used to rotate the first molars and expand the side teeth by  tipping.  The appliance is activated and adjusted by the orthodontist 2 or 3 times over 9 months.

Rapid Palatal Expansion

This is a robust device designed to create orthopedic expansion of the palate.  It is activated by the parent turning the ‘jackscrew’ in the middle of the appliance once or twice a day (according to the activation schedule recommended by the orthodontist). The appliance is usually in place for  3 months and then some form of retention appliance is required.
