Palatal Expander or Hyrax
A palatal expander or “Hyrax” is a custom fit appliance designed to widen your upper jaw. A wider jaw allows the upper and lower teeth to fit together and function properly as well as to allow for a broader, more attractive smile.
This “fixed” (non-removable) appliance fits in the roof of the mouth and is cemented to the upper posterior (back) teeth. Most patients will need to wear the palatal expander for a period of four to six months – as directed by your orthodontist. During this time, a screw will need to be turned to slowly expand and widen the upper arch.
There are several benefits to using a palatal expander:
- Creates space for crowded teeth
- Corrects a cross-bite of the back-teeth, if one was initially present
- Improves the width of the smile and its appearance
- Improves the airway if constriction of the nasal passages are blocking the airflow
