Synopsis:
Obstructive sleep apnoea syndrome (OSAS) is a respiratory sleep disorder that progresses into snoring, apnoea, and daytime sleepiness, and can occasionally affect all organs and systems. The most commonly used oral appliances expand the airway taking forward the mandible and reduces the collapse. Oral appliances are generally well tolerated although they have adverse effects on the teeth. This article gives an overview on the use of oral appliances, their clinical effectiveness, side effects, outcome predictors, tolerability and compliance.
