E ARCH EXPANDER
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.
