Comparisons of oral devices for snoring.

A study was performed on 19 types of oral appliances for snoring/obstructive sleep apnea. The appliances were categorized into two groups, mandibular advancers and tongue advancers. A set of limited criteria was developed by which an appliance could be evaluated, and the criteria were weighted. Evaluations were then performed on the appliances, and they were rated according to satisfaction of criteria. The rating table should help a dentist in selecting an appliance that will be accepted by the patient and effective in treating snoring/obstructive sleep apnea.
