Drawing inspiration from "The Mandibular E-Arch" by Neal Kravitz, the E-arch stands out as a fixed, spring-loaded expander tailored for the gradual expansion of both maxillary and mandibular arches. Initially designed for maxillary orthopedic expansion in cleft palate patients, its versatility shines in the mandible, where it can create up to 4-5 mm of arch space in the anterior region through orthodontic tipping and also distalize the first molars.

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.
