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

NCT07075211 | Completed

• 1 other identifier: A0803024OR
• Study Type: interventional
• Target: 14
• Locations: 1 country
• Sites: 1

Brief Summary

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.

Conditions

Constricted Maxillary Arch

Outcome Measures

Primary Outcomes (1)

• CBCT analysis : the mid palatal suture opening will be assessed from the axial slice.

  CBCT analysis: the mid palatal suture opening will be measures in millimetres at three different sites ( first premolar , second premolar, first molar). the metric measure will be placed at the two ends of the mid palatal suture

  3 weeks in each participant
