Snoreguards Explained: Silensor-SL, MSi and Fused Mandibular Advancement Devices

By Bridge Dental Laboratory · 8 July 2026 · Updated 8 October 2026

Snoring and mild obstructive sleep apnoea are areas where general dentistry can genuinely change a patient’s quality of life — and their partner’s. A mandibular advancement device (MAD) holds the lower jaw slightly forward during sleep, opening the airway and reducing or stopping the snore. But “a snoreguard” is not one appliance: the design you choose affects adjustability, comfort and how well the patient tolerates it. At Bridge Dental Laboratory we make three types — Silensor-SL, MSi, and fused.

Here is how to choose.

First, know your limits

Dental sleep appliances are appropriate for snoring and mild to moderate obstructive sleep apnoea, and for patients who cannot tolerate CPAP. Anyone with suspected significant sleep apnoea should be assessed and, where needed, diagnosed through the appropriate medical pathway before you fit a device. With that clinical governance in place, a MAD is a comfortable, well-evidenced option.

Silensor-SL

The Silensor-SL uses two connector bars that link the upper and lower splints and control the degree of advancement. It allows free lateral movement, so many patients find it comfortable, and the amount of protrusion can be adjusted by changing the connectors. It is a well-established, reliable choice for straightforward snoring cases where you want proven comfort.

MSi

The MSi is designed for adjustability, letting you titrate the advancement in steps to find the position that controls the snoring with the least protrusion. That incremental control is useful for patients who need a more precise setting, or where you expect to fine-tune over a few appointments to balance airway opening against jaw comfort.

Fused

A fused device joins the upper and lower elements into a single appliance set at a defined advancement. It is robust and simple, with fewer components to manage — a good option where you have already established the working protrusion and want a durable, uncomplicated device.

Choosing between them

  • Proven comfort, free jaw movement: Silensor-SL.
  • Fine, incremental titration: MSi.
  • Simple, robust, fixed advancement: fused.

Good retention is essential for all three — a device that dislodges overnight does nothing — which is why an accurate fit matters. A digital scan gives us the precision to make a device that stays put and stays comfortable.

FAQ

Common questions

Which patients are dental sleep appliances appropriate for?
Mandibular advancement devices are appropriate for snoring and mild to moderate obstructive sleep apnoea, and for patients who cannot tolerate CPAP. Anyone with suspected significant sleep apnoea should be assessed and, where needed, diagnosed through the appropriate medical pathway before a device is fitted.
What is the difference between the Silensor-SL, MSi and fused snoreguards?
The Silensor-SL uses two connector bars linking the upper and lower splints, allowing free lateral movement with advancement adjusted by changing connectors. The MSi is built for incremental titration, letting you fine-tune the advancement in steps. The fused device joins both elements into a single appliance set at one defined advancement.
Which snoreguard should I prescribe?
For proven comfort and free jaw movement, the Silensor-SL. For fine, incremental titration, the MSi. For a simple, robust device at a fixed advancement, the fused. Our free snoreguard finder narrows it down in three questions.
Can the advancement be adjusted after fitting?
On two of the three, yes. The Silensor-SL is adjusted by changing the connectors, and the MSi titrates in increments to find the position that controls the snoring with the least protrusion. The fused device is made to a single set advancement.
What do you need to make a snoreguard?
Upper and lower scans or impressions, plus the bite recorded in a protrusive position — as far forward as the patient comfortably tolerates. That registration is what tells us how much advancement to build into the appliance.
Why does retention matter so much on a mandibular advancement device?
Because a device that dislodges overnight does nothing. The appliance only advances the mandible while it stays seated, so an accurate fit is essential — which is why a digital scan is worth using where you can, for the precision it gives.
