The Forestadent Snap Lock Expander is a palatal expansion screw secured against unwanted back-turning by a flat spring that locks after each activation. The patient can feel the screw lock on every quarter turn, and the optimal position of the hole in the spindle makes reactivation straightforward. If over-activated, the screw can still be turned back.
