Oral devices to treat obstructive sleep apnea are considered Class 2 medical devices because they treat a recognized medical disease that can only be diagnosed by a physician; therefore, only medical insurers will pay for the cost. This presents a problem since an oral device can only be made by qualified medical provider who is knowledgeable of the oral structure. Dentists are very qualified in this area since they have extensively studied the mouth and jaw structure, however; most insurance companies have by-laws that do not allow a dentist to be in-network with that medical insurer unless the dentist is an oral surgeon.
