It is used to carefully broaden the upper jaw by exerting lateral pressure on the two halves of the maxilla (upper jaw) in patients with a narrow upper jaw. 2014-07-17 Introduction: The aim of this 2-arm parallel trial was to compare the dentoskeletal effects of the expander with differential opening (EDO) and the Hyrax expander in the mixed dentition. Methods: Patients aged 7-11 years with maxillary dental arch constriction and Class I or Class II sagittal relationships were randomly allocated into 2 study groups. Both appliances were efficient in correcting a transverse maxillary deficiency. The pure skeletal expansion was greater than actual dental expansion.
