Summary

Miniscrew-supported maxillary expanders provide advantages over conventional tooth-supported expanders. However, there is no consensus in the literature regarding their activation protocol. The purpose of the clinical trial is to evaluate and compare the effects of slow and rapid activation rates of miniscrew-supported expanders on the skeletal changes, dento-alveolar changes and the pain experience.

Conditions

  • Palatal Expansion Technique
  • Malocclusion
  • Posterior Crossbite
  • Maxillary Hypoplasia

Interventions

DEVICE

Miniscrew-Supported Maxillary Expander- Slow activation

A maxillary expander is supported on 4 palatal miniscrews. The appliance is activated slowly by turning the expansion screw once every other day to correct the transverse maxillary deficiency.

DEVICE

Miniscrew-Supported Maxillary Expander- Rapid activation

A maxillary expander is supported on 4 palatal miniscrews. The appliance is activated rapidly by turning the expansion screw twice per day to correct the transverse maxillary deficiency.
