The EDO promoted greater transverse changes in anterior region than Haas-type and greater transverse changes in posterior region of the maxilla than both conventional expanders. The appliance used for RME influences dental arch changes after treatment, therefore it is recommended to individualize the choice of expander depending on the clinical necessity of each case.
