Thornton Adjustable Positioner (TAP)

The Thornton Adjustable Positioner (TAP®) is a custom-made two-piece adjustable appliance that is worn while sleeping. The trays of the appliance snap over the upper and lower teeth and hook together. The design is based on the same principle as cardiopulmonary resuscitation (CPR). The airway must be opened to allow air to pass through the throat. The TAP® holds the lower jaw in a forward position so that it does not shift nor fall open during the night. This prevents the airway from collapsing. The more you pull your jaw forward, the more your airway will open.

The TAP® is the only mandibular advancement device that can be adjusted easily by the patient or practitioner while in the mouth. This feature allows the patient to always be in control of their treatment. The unique design also allows the patient to fine-tune their treatment position at home to achieve maximum results.

Most patients experience relief the very first night they wear their TAP®. Although it may take up to a week to get used to wearing a TAP® appliance, this is a small hurdle for patients. Nine in ten patients wear the device all night, every night—making the TAP® a highly effective solution for both snoring and sleep apnea.
