Summary

This study will evaluate the efficacy of rapid maxillary expansion (RME) and slow maxillary expansion (SME) in treating posterior crossbite using cone beam computed tomography.

The study sample will consist of 32 patients who suffer from a skeletal posterior crossbite. The sample will be allocated randomly into two groups: RME group and SME group.

The skeletal and dento-alveolar changes occurring after treatment will be assessed by using cone beam computed tomography(CBCT) radiographs.

Conditions

  • Posterior Crossbite

Interventions

PROCEDURE

Rapid Maxillary Expanding Device

The expansion screw will be turned two times in the first day, and then daily until the correction is achieved.

PROCEDURE

Slow Maxillary Expanding Device

The expansion screw will be activated every five days until correcting the crossbite.
