Three-dimensionally Printed Hyrax Versus Conventional Hyrax for Maxillary Arch Expansion in Adolescents
Sponsor: Ain Shams University
Summary
This clinical trial aims to compare the skeletal and dental effects of conventional Hyrax expanders and 3D-printed Hyrax expanders in adolescent patients with maxillary transverse deficiency. Using cone-beam computed tomography (CBCT) and digital models, the study evaluates the precision, customization, and treatment outcomes of both appliance types to inform evidence-based orthodontic treatment planning.
