What is an OAT and how does it work?
Oral Appliance Therapy (OAT) device definition
Oral Appliance Therapy (OAT) devices reposition the jaw with a custom-fitted mouthpiece. This holds the lower jaw in a forward position during sleep to keep the upper airway open, preventing apneas and reducing snoring.
OAT devices are available through sleep dental providers.
