[Research] This oral appliance could help you (and your partner) sleep better

An original design for an oral appliance developed in Hiroshima University Hospital can help sufferers of sleep apnea sleep more soundly

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 treatment of sleep apnea.
