Obstructive sleep apnea (OSA) is characterized by intermittent upper airway obstruction during sleep. It causes sleep fragmentation from brief arousal and affects social life by excessive daytime sleepiness. Moreover, OSA is considered a risk factor for cardiovascular complications and type 2 diabetes as associated features. The gold standard treatment for OSA is continuous positive airway pressure during sleep. However, if this treatment is frustrating to the patient or the apnea and hypopnea index is low or mild, alternative treatments for OSA must be found. One possible treatment is an oral appliance (OA) to improve the upper airway configuration. Dental clinicians have attempted to improve this respiratory condition caused by OSA by using OA, and at Tokushima University Hospital, OA therapy has been in use since 1993. Nishigawa et al. introduced a method to fabricate an OA and to investigate the effects of this therapy. In the present article, the method of OA fabrication was modified, and its effects were evaluated. Dental clinicians should have some knowledge about the mechanics of sleep and the management of sleep conditions so that they can cooperate closely with medical physicians. Thus, collaboration between the medical and dental fields can help patients attain healthy sleep.
