Based on the same principle as cardiopulmonary resuscitation (CPR), the TAP (Thornton Adjustable Positioner) sleep therapy device was designed to alleviate the symptoms of sleep apnea by keeping the patient’s airway open to allow for air to pass. The TAP device holds the lower jaw in a forward position, preventing the soft tissue of the throat from collapsing and obstructing the airway to reduce snoring and improve breathing. The appliance is made from two custom inter-occlusal parts that fit over the mandible and the maxilla. The upper portion of the device hooks into the lower portion, enabling the jaw to be pulled forward. TAP is now available in an “Elite” version that allows greater horizontal movement.
