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.
The EMA is indicated for patients with either a full or partial set of natural teeth. The patient’s remaining teeth should have sufficient height of contour for the device to gain retention at the gingival third, and the edentulous ridge must be fully captured in the impression.
