A negative pressure oral appliance therapy that uses suction to stabilize the soft palate and tongue during sleep.
iNAP (intra-oral negative airway pressure) is an alternative treatment for obstructive sleep apnea that uses negative pressure to stabilize soft tissues during sleep. The system consists of a soft silicone mouthpiece connected to a small vacuum unit. Gentle suction draws the soft palate downward and the tongue forward, preventing the collapse that causes obstruction. iNAP offers another option for patients seeking alternatives to CPAP or traditional oral appliances.
The iNAP mouthpiece creates a chamber around the tongue when placed in the mouth. A tube connects to a battery-powered vacuum unit that generates continuous gentle negative pressure. This suction stabilizes the soft palate in a downward position and holds the tongue forward without requiring jaw advancement. The open design allows normal breathing through both nose and mouth.
iNAP may be considered for patients with mild to moderate obstructive sleep apnea who prefer an alternative to CPAP or don't want the jaw advancement of traditional oral appliances. It may be helpful for patients who have TMJ problems that preclude mandibular advancement devices.
Unlike mandibular advancement devices, iNAP doesn't reposition the jaw, avoiding TMJ stress and bite changes.
The silicone mouthpiece is softer than hard acrylic oral appliances, potentially improving comfort.
For patients who've failed other treatments, the unique negative pressure approach may succeed where others haven't.
The open design permits breathing through the mouth, unlike nasal CPAP.
Most side effects are minor and can often be resolved with simple adjustments.
Using the device correctly takes practice. Initial nights may be challenging.
The suction and airflow may cause oral dryness in some users.
The vacuum unit, while quiet, produces some sound that may bother light sleepers.
Compared to CPAP and traditional oral appliances, less independent clinical research exists on iNAP.
Proper fit of the mouthpiece is important for effectiveness and comfort.

Various mouthpiece sizes accommodate different mouth and tongue sizes.
Get comfortable with the device while awake before attempting to sleep with it.
Work with your provider to ensure the mouthpiece is the right size and positioned correctly.
While mouth breathing is possible, nasal breathing may enhance effectiveness.
Regularly clean the mouthpiece and check the vacuum unit to maintain hygiene and function.
Track symptoms and consider follow-up testing to ensure the device is adequately controlling your OSA.
