Summary

Rapid maxillary expansion (RME) is a commonly used orthodontic treatment in patients with maxillary constriction to provide skeletal expansion, correct posterior crossbite and resolve naso-respiratory problems by reducing oral respiration.The aim of this randomized controlled trial was to evaluate the effects of tooth-borne, tooth tissue-borne and bone-borne RME appliances on sleep quality with polygraphy. The null hypothesis was that there is no difference for the sleep quality between the appliances.

Conditions

  • Sleep Apnea Syndrome
  • Rapid Maxillary Expansion

Interventions

PROCEDURE

Rapid Maxillary Expansion Treatment

The patients were treated with KBME, Hyrax and MIDME maxillary expansion appliances, respectively. All expansion appliances containing a Hyrax expansion screw positioned parallel to the second premolars and were used to correct the posterior crossbite. In the MIDME group, two mini-screws with a diameter of 1.6 mm and a length of 10 mm are located on the right and left sides between the roots of the 2nd premolar and 1st molar teeth with 60-70° angle. KBME and Hyrax expansion appliances were cemented with glass ionomer cement and MIDME was cemented with using the light-cured composite. Same protocol was applied to all patients during RME treatment. Expansion screws in all groups were activated by two turns a day.
