Abstract

Objective: This study aims to assess the efficacy of maxillary skeletal expansion using the MARPE (Micro-Implant Assisted Rapid Palatal Expander) appliance in a cohort of Vietnamese patients with matured midpalatal sutures. Subjects and methods: A non-controlled clinical trial was conducted to evaluate pre- and post-treatment outcomes in 24 cases presenting with maxillary constriction and closed midpalatal sutures (cervical vertebrae maturation stage 5 or 6). Variables measured included maxillary dental arch width, basal bone width, length and width of the midpalatal sutures, and inclination of the root of posterior maxillary teeth. These measurements were assessed using CBCT images obtained before and immediately after maxillary expansion. Conclusion: The mid-palatal suture is succefully separated in skeletally mature patients immediately after MARPE
