Effect of Mini-screw Assisted Rapid Palatal Expansion on Midpalatal Suture in Post-pubertal Patients: a CBCT Study

a device is going to be placed in the palate to non-growing patients who are diagnosed to have a constricted maxillary arch and require an expansion of the maxillary arch in their treatment plan. the device is composed of two mini screws that will be placed in the palate which are connected to a hyrax with orthodontic bands on first maxillary molars. the activation of the device will be for 3 weeks 2 turns on the day of placement and 1 turn every day for 3 weeks. a CBCT x-ray will be taken before and after expansion to see the effect of MARPE on the mid-palatal suture.
