Doctors have always been hesitant about prescribing dental devices for sleep apnea patients because of the lack of research and testing into their reliability. That is gradually changing.
A team of researchers from the University of New South Wales in Australia have been testing these oral devices on sleep apnea patients. Dr. Peter Cistulli, MD, PhD, head of the research team, reports that two thirds of those tested showed definite improvement and a drop in apneas from 25 a night to five or less.
The current treatment of choice for obstructive sleep apnea, CPAP (Continuous Positive Airway Pressure,) is very effective, but it's also difficult for some sufferers to adjust to using the machine. Many become disillusioned, use it for only a few hours a night, or discontinue its use altogether. CPAP supplies a continuous stream of air up the nose forcing the air passages to remain open. This is done by the use of a small air compressor and a facial mask.
Several oral devices are available. Two of the most popular are the splint and the mandibular advancement device. The splint holds the tongue in a position that allows the air passage to remain open. The mandibular advancement device, or MAD, forces the lower jaw forward to allow more room for air to flow. There may be some side effects with MAD, like pain in the jaw, but many people use it without a problem.
These devices work best for people who have mild or moderate sleep apnea, but they have been used in those with severe sleep apnea with some degree of success. They were originally devised for people who snore and work well for this complaint.
In a small number of people, the apnea has become worse when using the device. It is advisable to have periodic testing to assure that the system is working. CPAP is still the best treatment for obstructive sleep apnea, but for those who are so discomforted by the machine that they are tempted not to use it, the dental or oral devices might be a viable substitution. Always follow the advice of your sleep specialist or doctor.
