A small forward shift that opens the airway

The MSi is a mandibular advancement device — two custom-fitted splints joined by adjustable titanium arms. Worn at night, it holds the lower jaw gently forward to keep the airway clear and reduce the vibration that causes snoring.

  1. Positions the jaw forward

    Upper and lower splints connect via adjustable titanium hooks, holding the lower jaw in a controlled protrusive position throughout the night.

  2. Opens the upper airway

    Forward positioning of the mandible pulls the tongue and surrounding soft tissues away from the back of the throat, keeping the airway open during sleep.

  3. Quiets the vibration

    With a clearer airway, the soft tissues no longer vibrate as air passes through — the source of snoring — and breathing becomes smoother and quieter.

Engineered to go the distance

Every part of the MSi is designed to be serviceable and replaceable, giving patients long-term value and a snoreguard that withstands even heavy bruxism.
