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.

The Nociceptive trigeminal inhibition tension suppression system (abbreviated to NTI-TSS, or NTI-tension suppression system), is a type of occlusal splint that is claimed to prevent headache and migraine by reducing sleep bruxism (night-time tooth clenching and grinding). Sleep bruxism is purported to lead to a hyperactivity of the trigeminal nerve, often triggering typical migraine events. The hyperactivity of trigeminal neurons during trigemino-nociceptive stimulation is a proposed cause of migraine and is correlated with imaging of migraine sufferers. The objective of the NTI-TSS is to relax the muscles involved in clenching and bruxing, thus supposedly diminishing the chances for migraines and tension headaches to develop through the reduction in nociceptive stimulation normally caused by parafunctional activity. It is sometimes used for temporomandibular joint dysfunction (TMD).
The NTI-TSS is a small transparent plastic device which is, in its most widely used form, worn over the front four teeth, of either arch, at night, and intended to prevent contact of the canines and molars. It is normally fitted by a dentist trained in the technique, and is constructed by a dental laboratory.
