The Accu3D Metal Printed HAAS (Acrylic) appliance includes an acrylic plate positioned within the palate vault.  The plate features an expansion screw that allows for adjustment. Dr. Haas theorized that enhanced palatal coverage minimizes tipping and facilitates more substantial bodily movement due to the added support on the palate.

Additionally, each appliance comes with a custom swivel key.  3D metal printing allows for the bands of the Haas to fit most accurately for your patient’s dentition.
