Transform Your Patients’ Lives with Better Sleep

Obstructive sleep apnea is a breathing disorder where the airway completely collapses and airflow is obstructed. People with this condition often wake up gasping for air or choking in the middle of the night. The OASYS Hinge Appliance is designed to gently shift the lower jaw forward during sleep, which activates airway muscles and ligaments to prevent the airway from collapsing. The OASYS Hinge Appliance is designed with comfort in mind for patients to wear throughout the night, helping to improve health and quality of life.

Medicare-Approved for Mild to Moderate Obstructive Sleep Apnea

The OASYS Hinge Appliance is eligible for Medicare reimbursement under code E0486. This benefit further expands opportunities for dentists to provide therapy to patients suffering from snoring and mild to moderate obstructive sleep apnea.

Patient Satisfaction

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

Improved Health

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

A mandibular advancement device for obstructive sleep apnea reduces nocturnal blood pressure in women. 5

What Snoring and Obstructive Sleep Apnea Looks Like

Normal breathing (left): open airway, tongue is relaxed (falling back slightly). Snoring (middle): partially blocked airway, when the constricted airway causes vibration. Obstructive sleep apnea (right): fully blocked airway.

What snoring and obstructive sleep apnea looks like



To reduce snoring and mild to moderate sleep apnea (OSA) in patients 18 years or older. The appliance is worn while sleeping to support the lower jaw in a forward position as determined by the dentist. The appliance is removable by the patient.
