Treatment for snoring and sleep apnoea

Mandibular advancement appliances are connected upper and lower removable dental ‘plates’ worn during sleep. The appliance postures the lower jaw forward, increasing the size of the airway at the back of the throat during sleep giving a non surgical treatment for snoring and mild obstructive sleep apnoea. The design and materials used for construction of a mandibular advancement appliance can vary. We offer the most effective laboratory-manufactured devices moulded specifically to patient impressions.
