Introduction Video of MSE

MSE is indicated in the treatment of posterior cross bite, Class III malocclusions and it is able to improve nasal airflow and breathing. Recent publications show the positive effects also in the therapy of Obstructive Sleep Apnea (OSA).

The main difference between
The MSE and Others.

" The Maxillary Skeletal Expander (M.S.E.) can effect both dental and skeletal expansion.The adverse clinical consequences of RPE and SARPE in high-angle cases will be get solved by M.S.E. Also, many patients who requiring maxillary expansion often have narrow nasal airways, and positive changes in nasal airway with application of M.S.E. are common. "

Benefits & Contraindications

Benefits

Mostly Skeletal Expansion: less bone bending and dental tipping compared to RPE and surgically assisted maxillary expansion (SARPE)
Less invasive than SARPE and Orthognathic Surgery
Significant increase in upper airway volume: nasal obstruction, sleep apnea
MSE causes expansion of the surrounding structures
Vertical control in high angle cases
FM and MSE for Class III correction
MSE can be used for mature patients
