The HAAS appliance features an acrylic plate in the palate’s vault with an expansion screw and lingual arms laser-welded to acrylic-integrated bands. Dr. Haas emphasized its palatal coverage for reduced tipping and enhanced bodily movement. Each comes with a swivel key featuring an activation tracker. Our 3D-printed HAAS Expander ensures a precise fit. The process? A scan, followed by delivery—no separators needed. Our digital experts craft designs for optimal retention, with metal snug to the lingual and options to cup both lingual and buccal. Experience a transformative approach to patient care with this advanced expander.

Description

Framework:

  • Contours the palate about 1-1.5mm off the tissue with acrylic anchors at both wire ends.
  • Extends lingually from distal of 6 to mesial of 4(d).

Screw:

  • Centered at midline and 5(e)/6 area.
  • Positioned parallel to the occlusal surface and 1-1.5mm from the palate for comfort.
  • Magnum screw is an alternative if standard screw height exceeds 8-10mm from the vault.

Acrylic:

  • Supports the vault and fully encases the screw, yet allows keyhole access.
  • Outer edges are 4-5mm from gingival margins, rounded, and at least 1.5mm thick.
  • Cut along the skeletal midline to facilitate screw function.
