Haas Palatal Expander
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.
