The EMA (Elastic Mandibular Advancement) is a custom-made removable intra-oral appliance created for noninvasive treatment of snoring and obstructive sleep apnea (OSA). The appliance is designed to both advance the lower jaw (mandible) and open the bite to allow for less restricted airflow during sleep. EMA appliances help promote a deeper, more restful sleep by preventing snoring and relieving the symptoms of obstructive sleep apnea (OSA). The EMA does not interfere with breathing through the mouth, even in cases of congested nasal passages. The EMA has many options for patient advancement with 5 strap lengths and 4 different elastic tension options. Non-restricted side-to-side (lateral) or front-to-back (protrusive) movements of the jaw are possible while wearing the appliance due to varying elastic bands.
