Oral appliances in the management of obstructive sleep apnoea syndrome

Obstructive sleep apnoea (OSA) is a term used to describe repetitive episodes of complete or partial upper airway obstruction that occur during sleep. It is a highly prevalent medical disorder and a challenge to treat. The treatment options include continuous positive airway pressure, oral appliances and surgical interventions depending on the severity of the condition. Among these, oral appliances are commonly used as primary therapy for the treatment of OSA because these appliances are designed to either encourage maxillary transverse development or advance the mandible, which will significantly reduce the OSA. This narrative review emphasises the role of various oral appliances in the treatment of OSA and will serve as a guide to clinicians in choosing the proper dental appliance.
