Abstract

Objectives: To describe the vertical and anteroposterior changes on cephalometric radiographs in patients after rapid maxillary expansion with minivis support at the Hanoi Central Odonto-Stomatology Hospital and the Department of Odonto-Stomatology, the Hospital of Hai Phong Medical University from 2020-2022. Materials and methods: 36 patients treated maxillary expansion by MSE appliance. Their cephalometrics were taken before treatment (To),  immediately after stopping the expansion (T1) and after 6 months of maintenance (T2). The parameters on the  cephalometric assessing the change at three different time points were collected, analyzed and verified by suitable tests. Results: The parameters evaluated vertically and anteroposteriorly at three time points showed no statistically significant changes.
