Maxillary Transverse Deficiency (MTD) in adults presents with constricted maxillary arches, posterior crossbites, dental crowding, and functional and aesthetic concerns. Unlike pediatric patients, adult midpalatal sutures are often fused or highly interdigitated, limiting conventional rapid maxillary expansion (RME) and increasing the risk of dental tipping and alveolar bending. Contemporary approaches, including Surgically Assisted Rapid Maxillary Expansion (SARME) and Mini-implant Assisted RME (MARPE), enable predictable skeletal expansion while minimizing dental side effects. SARME involves osteotomies to overcome sutural resistance, whereas MARPE utilizes skeletal anchorage via palatal miniscrews to transmit expansion forces directly to the basal bone. Both methods improve occlusal function, facial aesthetics, and airway dimensions, though complications such as root resorption, periodontal changes, or surgical risks may occur. Careful patient selection, imaging assessment, appliance design, and retention protocols are essential for long-term stability. Advances in digital planning and minimally invasive techniques continue to enhance the safety and efficacy of adult RME.
