The XD Hyrax Expansion Screw is an essential orthodontic device engineered specifically for fixed rapid palatal expansion (RPE). Crafted from premium biocompatible, medical-grade stainless steel, this expansion screw provides exceptional mechanical rigidity, smooth adjustment, and maximum resistance to oral corrosion.
Its robust threaded center spindle is built with dual guide pins to prevent unwinding and withstand heavy lateral orthopedic forces. The body features permanently laser-marked directional arrows alongside size marking (9 mm) for foolproof chairside or at-home activation using the included swivel safety key. The straight, extended retention legs allow easy contouring, cutting, and laser welding or soldering directly to molar bands or cast splints.
Key Features
High Orthopedic Force Delivery: Engineered to transfer uniform lateral pressure to split the midpalatal suture without bending or jamming.
Laser-Marked Directional Arrows: High-contrast engraved arrows provide clear visual guidance for turning direction during patient activation.
Extended Retention Arms: Straight, heavy-gauge wire extensions offer complete versatility for custom bending and soldering to molar/premolar bands.
Stable Dual-Guide Design: Parallel guide pins flank the central expansion spindle to ensure distortion-free, balanced symmetrical movement.
Included Activation Safety Key: Comes with an ergonomic activation key designed for secure grip and smooth spindle engagement.
Biocompatible Construction: Manufactured from corrosion-resistant surgical stainless steel to ensure patient safety and hygiene throughout treatment.
