In 2015, the AASM and AADSM independently reviewed every FDA-cleared oral appliance on the market. They measured one thing: which devices actually reduce sleep apnea. TAP didn’t just pass — it led the field in every severity category.

Only oral appliance to outperform all competitors in moderate cases
Sleep apnea is tracked using AHI — the Apnea-Hypopnea Index. It counts how many times per hour your breathing stops or becomes dangerously shallow during sleep. The higher the number, the more serious the condition. Here’s how severity is classified — and what it takes to call a treatment successful.

Most patients assume CPAP is the only treatment that truly works. The 2015 AASM/AADSM independent review tells a different story — and adds a critical dimension that raw AHI numbers alone don’t capture: whether patients actually keep using their treatment.

The AASM/AADSM review didn’t just compare TAP to CPAP — it put every FDA-cleared oral appliance head-to-head. The results were striking. This isn’t a marketing claim. It’s what independent reviewers found when they ran the numbers — with no financial interest in the outcome.
In severe cases, every other device in the review failed to meet the clinical success threshold. TAP alone cleared the bar.
Out of all FDA-cleared oral appliances reviewed, just three met clinical success criteria in moderate cases. TAP achieved the highest reduction of the three.
Independent comparison of every FDA-cleared oral appliance measured against both CPAP and oral appliance clinical success criteria. Studies sourced from the 2015 AASM/AADSM clinical review.

Only appliances available in the U.S. and cleared for the treatment of sleep apnea were listed. Not all failures were listed. For a full list of studies, contact Airway Management or refer to the AADSM Clinical Guidelines.
Download Full Report (PDF)Most oral appliances work by advancing the jaw — but how they do it varies significantly, and that difference directly affects clinical outcomes. TAP is the only device with a single point of central adjustment — a patented midline mechanism that gives clinicians and patients precise, incremental control over jaw position.
Patients fine-tune their TAP at home, while wearing it — no clinic visits required. More precise fit means better airway opening and better outcomes.
TAP can move the lower jaw farther forward than any other oral appliance on the market — reaching the therapeutic position other devices simply can’t achieve.
Central adjustment distributes force evenly across the jaw — preventing the irregular bite and TMJ discomfort common with bilateral-thrust devices.
dreamTAP takes everything that makes TAP the clinical leader and refines it into the most patient-friendly design ever produced by Airway Management.
TAP has been independently reviewed against every competing device on the market — and it leads in every category that matters for real-world patient outcomes. Not because of marketing. Because of the science.
