For a Better Night’s Sleep

The EMA (Elastic Mandibular Advancement) oral appliance is a customized removable appliance created for the noninvasive treatment of snoring and obstructive sleep apnea (OSA). The appliance is designed to both advance the mandible and open the bite to allow for less restricted airflow during sleep.

EMA devices help promote a deeper, more restful sleep by preventing snoring and relieving the symptoms of OSA. The EMA does not interfere with breathing through the mouth, even in cases of congested nasal passages. It has many options for advancement with nine strap lengths (13 mm–21 mm) and four different elastic tension options, indicated by color. The shorter the strap, the farther the mandible is advanced. The 36 different straps allow for the most effective repositioning of the jaw with maximum comfort. Due to the varying elastic bands, non-restricted lateral/protrusive movement is possible while wearing the device.

Oral appliance therapy (OAT) is very effective in treating patients with sleep-disordered breathing, with a compliance rate shown to be as high as 90% over a 2.5-year period.1

OAT is associated with greater patient satisfaction than nasal continuous positive airway pressure (CPAP) therapy.2

In a randomized crossover trial comparing OAT to CPAP in patients with obstructive sleep apnea, about 81% preferred OAT.3


Among patients with obstructive sleep apnea, both continuous positive airway pressure (CPAP) and mandibular advancement devices (MADs) were associated with reductions in blood pressure. Network meta-analysis did not identify a statistically significant difference between the blood pressure outcomes associated with these therapies.4
