Palatal Expanders

Memory Expander
This 8mm screw has built in Niti coil spring that allows for 5 turns equaling 1mm to be made at one time. After the 5 inital turns are made the appliance slowly exerts the expansion through the built in springs until the 1mm of expansion is met. At that point you would reactive the appliance in the same way to achieve another 1mm of expansion.

Spring Jet Expansion Appliance
This family of expansion appliances use light forces created by NiTi coil springs. Activated in the doctor's office, no patient compliance is necessary. Each time the patient returns to the office the doctor unlocks the sliding mechanism and compresses the coil spring again thus reactivating the appliance.
