Newly developed oral appliance offers fresh hope for people suffering from obstructive sleep apnea (OSA). The findings of the study are published in the journal Sleep Disorders.
A team of researchers measured a novel treatment for sleep apnea developed at Hiroshima University Hospital with positive results. By measuring patients lying down flat, the researchers stimulated sleep conditions and measured the patient's airways using 3D imaging. The study confirmed that the treatment is effective at opening the airways and warrants further collaboration between dentists and doctors in the treatment of sleep apnea.
Obstructive Sleep Apnea
Obstructive sleep apnea should be suspected in overweight middle aged adults who snore loudly and which can cause interruption of breathing for 10 seconds or more and this results in reduced blood o

Obstructive sleep apnea is a condition that causes throat muscles to relax and narrows the airways of those affected while they are asleep. Snorting, choking or gasping while sleeping are the indicators of the condition. Usually, the sufferers' partner notices before they do!
People with mild to moderate sleep apnea experience daily fatigue and a shortened attention span from lack of sleep. Sleep apnea can also have more serious consequences; people have died from very severe forms of the condition.

Sleep is a barometer of good health in the elderly. Sleep problems in the elderly are controlled by various external and internal factors.
"Your eyes are closed, but you're not resting," explains Dr. Cynthia Concepción-Medina, Research Assistant at the Department of Orthodontics at Hiroshima University Hospital who contributed to the study with her colleagues Associate Professor Hiroshi Ueda and Dr. Yu Matsumura.
Treatments include a continuous positive airway pressure (CPAP) machine (a mask worn by the patient that delivers air pressure throughout the night) or one-piece oral appliances.
The Department of Orthodontics at Hiroshima University Hospital developed an oral appliance to help patients with mild to moderate sleep apnea. This appliance brings the jawbone forward to enlarge the air passageways at the back of their mouth. Each appliance is custom made for each patient and allows jaw movement, so it doesn't affect patient's teeth or change the shape of their face.
"This is like when you have to use glasses, you have to wear them every time you want to see properly so [patients] have to wear this appliance every time [they] want to sleep better." according to Dr. Ueda.
To further investigate how well the appliance works the research team, led by Dr. Matsumura, scanned a group of patients with mild-to-moderate sleep apnea using Multislice Computed Tomography (MSCT)-- a type of X-ray where the machine rotates around an object, and it takes a picture each time it rotates. This data is then combined to see a 3D object and is a fast and precise method of scanning.
Previous research usually measured patients standing up, which does not simulate sleeping conditions. This study measured the change in airway space of 13 patients lying flat. The team found that the appliance had a positive effect on patients: wearing it almost halved the number of times the patients had sleep apnea episodes during the night and widened their airways to allow easier breathing.
"I think it's unique research because we are dentists, but we can contribute to improve the [patient's] sleep situation or breathing situation," says Dr. Ueda.
This study indicates promising effects of this treatment and the team hopes that they can continue this collaboration between the dental and the medical field.
