Brief 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.

Outcome Measures
Primary Outcomes (1)
Correction of posterior crossbite
The palatal cusps of the maxillary posterior teeth approximated the lingual cusps of the mandibular posterior teeth.
After active expansion (up to 3 weeks). The evaluation of the result has been made by the physician with intraoral clinical examination.
Secondary Outcomes (7)
Polygraphic assessment of sleep parameters

Study Arms (3)
Tooth tissue-borne (KBME) expander
EXPERIMENTALIn this tooth tissue-borne appliance, the occlusal surfaces of the molar and premolar teeth and half of the palatinal and buccal surfaces are covered with heat polymerized acrylic. Hyrax expansion screw is in the midline, as far as possible to the palate positioned close and parallel
Tooth-borne (Hyrax) expander
EXPERIMENTALIn this tooth-borne expansion appliance, orthodontic bands are placed on the right and left 1st premolar and 1st molar teeth of the patients and the bands are soldered to the Hyrax expansion screw. The expansion screw is in the midline, as far as possible to the palate positioned close and parallel
Bone-borne (MIDME) expander
EXPERIMENTALThis bone-borne expander includes 2 mini-screws with a diameter of 1.6 mm and a length of 10 mm on the right and left sides, coinciding between the roots of the 2nd premolar and 1st molar teeth in addition to the hyrax expansion screw.
Interventions
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.
