Snap Lock RPE

The Snap Lock Expander is designed to prevent unwinding of the screw. It does not turn back unless the doctor or patient turns it back. The hole in the spindle is always in the right place for reactivation for parents reducing frustration. When the Snap Lock Expander is properly activated by 1/4 turn, both the patient and doctor will be able to feel the screw lock. If the appliance is overactivated, the Snap Lock Expander can be turned back. With each expansion appliance, we provide a custom swivel key that has an integrated activation recording tool directly on the handle.
