The expander with differential opening (EDO) is a new device proposed to treat maxillary constriction individualizing the expansion in the anterior and posterior regions of the dental arch. The influence of expander with EDO in the nasal cavity width and height was not previously described. This presentation will aim to present the EDO and compare the nasal cavity skeletal changes between the EDO and the fan-type expander (FE).
Learning Objectives:
After this lecture, attendees will be able to:
Describe the expander with differential opening (EDO).
Compare the nasal cavity skeletal changes between the EDO and the fan-type expander (FE).
Discuss the importance of rapid maxillary expansion in pediatric patients with obstructive sleep apnea.
