A Haas Expander is a fixed rapid palatal expansion appliance designed to correct transverse maxillary deficiencies by widening the upper jaw. Featuring a central expansion screw supported by acrylic pads that contact the palate, the Haas Expander distributes expansion forces to both the teeth and palatal tissues, promoting effective skeletal expansion in growing patients.
At Times Dental Lab, every Haas Expander is custom fabricated to ensure an accurate fit, reliable activation, and long-term clinical performance.
