Dental arch changes comparison between expander with differential opening and fan-type expander: a randomized controlled trial

ConclusionsMaxillary arch width and shape changes were distinct between the EDO and the FE. Greater transversal increases of the anterior and posterior regions were observed for the FE and the EDO, respectively. A slightly greater mandibular spontaneous expansion was observed for the EDO only at the molar region.Trial registrationNCT03705871.
