Sleep Apnea · CPAP Alternatives

CPAP didn't work for you — that doesn't mean OSA treatment has to stop

CPAP non-tolerance is common, documented, and understood. For patients who have genuinely tried CPAP and cannot use it consistently, oral appliance therapy is recognized by the American Academy of Sleep Medicine as an appropriate alternative — after your physician confirms the switch.

Why CPAP non-tolerance matters — and what to do about it

CPAP (continuous positive airway pressure) is highly effective when used consistently — but studies consistently show that 30–50% of patients prescribed CPAP are non-adherent at 1 year, typically defined as using the device fewer than 4 hours per night on fewer than 70% of nights. Untreated OSA carries real cardiovascular, metabolic, and cognitive consequences. An alternative that patients actually use is often better than a gold-standard treatment that sits in the drawer.

The 2015 AASM/AADSM clinical practice guideline states: “We recommend that sleep physicians prescribe oral appliance therapy, rather than no therapy, for adult patients who are intolerant of CPAP therapy or who prefer alternate therapy for mild, moderate, or severe OSA.” This is a strong recommendation based on multiple randomized controlled trials.

Switching or supplementing requires your physician's involvement — not because of regulatory formality, but because a follow-up sleep study is needed to confirm the appliance is controlling your apnea adequately.

Combination therapy: appliance + CPAP together

For some patients — particularly those with severe OSA who need CPAP but struggle with high pressure settings — wearing a mandibular advancement device simultaneously reduces the required CPAP pressure. Lower pressure often means better mask seal, less aerophagia, and improved comfort and compliance.

This is not a first-line approach, and it is not appropriate for every patient. Your sleep physician prescribes and titrates the combination. We provide and manage the appliance component.

What to expect — switching to an oral appliance

1. 1

   Physician authorization

   Talk to your sleep physician about switching. They review your CPAP data, your intolerance reasons, and your OSA severity, then provide a prescription and letter of medical necessity for OAT. Bring CPAP download data if available.

2. 2

   Dental sleep consultation

   We review your records, screen your dental anatomy and TMJ health, and verify insurance benefits. No obligation at this stage. Bring your sleep study report, physician prescription, and medical insurance card.

3. 3

   Impressions and fabrication

   We take digital or physical impressions. Your custom appliance is fabricated by a specialized laboratory — typically ready in 2–3 weeks.

4. 4

   Fitting and initial titration

   We seat the appliance and instruct you on use and care. Jaw position starts conservative and advances incrementally over 4–8 weeks until therapeutic position is reached.

5. 5

   Follow-up sleep study

   Once titration is complete, your sleep physician orders a follow-up study (HST or in-lab) to confirm your AHI has been reduced to a therapeutic target. We provide your physician with titration records.

6. 6

   Ongoing annual follow-up

   Annual check of appliance condition, bite, and TMJ health — coordinated with your sleep physician. Most insurers require documented annual follow-up for a future replacement appliance.
