Snoring splint or CPAP? The comparison
In brief: For severe obstructive sleep apnea, CPAP positive-pressure therapy is the first choice. For mild to moderate sleep apnea and for snoring, the custom-made mandibular advancement splint is a guideline-based alternative that is often better tolerated in everyday life – no mask, no device, no noise. Which therapy is right for you depends on the severity, anatomy and your needs, coordinated between sleep medicine and dental sleep medicine.
The two therapies at a glance
CPAP: positive-pressure therapy with a mask
With CPAP therapy (Continuous Positive Airway Pressure), a device keeps the airway open with a slight air overpressure delivered through a nasal or full-face mask. It is the most effective method for suppressing breathing pauses, and the standard for severe sleep apnea. The challenges are getting used to the mask and device, pressure points, dry mucous membranes and the noise of the device – part of the reason some people do not use the therapy consistently in the long term.
Mandibular advancement splint: a dental splint without a mask
The custom-made splint holds the lower jaw slightly forward during sleep and thus keeps the airway open. It is quiet, needs no electricity, fits in any wash bag and is well tolerated in everyday life by most people. For mild to moderate obstructive sleep apnea and for snoring, its effectiveness is well documented; in the guidelines it is established as a treatment option. The prerequisites are a sufficiently stable set of teeth and professional fitting.
Splint and CPAP in direct comparison
| Mandibular advancement splint | CPAP | |
|---|---|---|
| Suitable for | Snoring, mild to moderate sleep apnea, CPAP intolerance | All severity levels, first choice for severe sleep apnea |
| Effectiveness | Well documented for the right indication | Greatest at reducing the AHI |
| Comfort | No device, no mask, silent | Mask, tube and device; getting used to it required |
| Travel | Fits in your trouser pocket | Device must come along, electricity needed |
| Possible side effects | Initially salivation, muscle tension; rarely changes in tooth position | Pressure points, dry mucous membranes, noise |
| Long-term use | High wearing rate in everyday life | Some discontinue the therapy |
| Costs & coverage | CHF 1,500–2,700; with a medical prescription usually covered in full by basic insurance | Coverage by basic insurance with a corresponding diagnosis |
Important: in studies, both therapies achieve often comparable results in everyday life for mild to moderate sleep apnea – also because the splint, when worn consistently, is used more than the mask.
CPAP is not tolerated – what now?
If you cannot tolerate CPAP therapy despite severe sleep apnea, the mandibular advancement splint is a recognised second-line therapy: weaker in effect than CPAP, but clearly better than leaving it untreated. In this case, mandatory basic health insurance usually covers the cost of the splint in full with a medical prescription. The switch is made in coordination with your sleep physician – follow-up checks confirm the treatment success.

Frequently asked questions about the comparison
Can I switch from CPAP to the splint?
Yes – for mild to moderate sleep apnea or in the case of CPAP intolerance, switching is a recognised option. It is done in coordination with your sleep physician; the treatment success is then monitored.
Can you combine the splint and CPAP?
In selected cases, yes: some people use CPAP therapy at home and the splint when travelling. Whether a combination makes sense for you is something we clarify together with your treating physicians.
Who decides which therapy I get?
The diagnosis and severity classification are provided by sleep medicine. On this basis, we advise you on dental terms and clarify whether you are suitable for a splint. The decision is always made together – based on findings, anatomy and your needs.
