Oral appliances (OAs) are devices that can be used in the treatment of sleep disorders, more specifically, sleep apnea. To those who obtain proper diagnosis, there are two main non-surgical treatment options: oral appliances or positive airway pressure. While both techniques have their benefits and drawbacks, OAs have been increasing in in popularity as an alternative treatment method as they are less invasive and expensive. Frost & Sullivan anticipates that the US OA market will double by 2020, with custom appliances seeing five times the revenue increase during that period.
