3D Evaluation of Maxillary Expansion Methods

This controlled prospective clinical trial aims to evaluate the effectiveness of different maxillary expansion methods in children with maxillary transverse deficiency. A total of 60 participants will be included: 20 patients will receive Invisalign Palatal Expander (IPE), 20 will receive acrylic cap splint Rapid Maxillary Expansion (RME), and 20 will serve as an untreated control group. Three-dimensional (3D) intraoral and extraoral scans will be taken at the end of expansion, at 3 months, and at 6 months. Primary outcomes include maxillary arch width, first molar angulation, palatal surface area, and palatal volume. Secondary outcomes include soft tissue changes in the facial region. This study provides a direct comparison between a traditional and a modern digital expansion method, generating evidence for clinical decision-making in pediatric orthodontics.
