Hyrax RPE With Facemask Hooks

The RPE is typically used in phase I treatment to widen the arch, either prior or during fixed treatment. Facemask hooks are last welded for Class III correction. Our expanders come in 7 or 11 mm screws and vary in activation depending on the style. Our standard expander uses the 11mm Leone expander and has welded lingual wires expanding to the premolars or cuspids. It is constructed entirely of biomedical stainless steel, and the housing is completely smooth with no rough areas to aid in hygiene. With each expansion appliance, we provide a custom swivel key that has an integrated activation recording tool directly on the handle. Tip: If you find an expander is hard to turn, run under warm water to loosen the threads.
