The Hyrax rapid palatal expander is one of the most widely used fixed orthodontic devices for maxillary expansion. It features two metal wings with precision-fit bands that anchor securely to the upper molars, providing stability during treatment. Used mainly to treat maxillary insufficiency, arch constriction, and posterior crossbite, the Hyrax expander is increased by rotating a central screw using a key—gradually applying force to separate the mid-palatal suture and broaden the upper jaw.
Orthodontists generally recommend that the expander be worn for a minimum of six months, following which one must change to a retainer to stabilize. At Bestodental, our highly trained technical team designs and prepares individualized Hyrax expanders tailored to each patient’s anatomy and treatment requirements—attaining optimal clinical outcome and patient comfort.
