Evaluation of the Effect of Different Rapid Maxillary Expansion Appliances on Airway by Acoustic Rhinometry

46 participantsStarted 2016-07-01

Plain-language summary

Rapid maxillary expansion (RME) is an orthodontic treatment based on the principle of opening the midpalatal suture with the effect of orthopedic forces. The aim of this randomized clinical study was to evaluate and compare the effects of tooth-borne, tooth-tissue borne, and bone-borne rapid maxillary expanders on nasal airway by using AR. The null hypothesis was that there is no difference for the effect on nasal airway between the appliances.
