Maintaining and Adjusting a Dorsal Appliance

The Dorsal has become one of the most popular choices for snoring and obstructive sleep apnea. The two-piece construction is designed for ultimate patient comfort. This guide will help you identify the different parts of your new Dorsal sleep apnea device. 

The Parts of a Dorsal Appliance

How to make an adjustment

Hold the upper device with the calibration screw facing toward you. 

Forward Adjustment 

Fit your calibration tool into the keyhole and rotate 90ᵒ in the direction of the arrow on the device. 

Backward Adjustment 

Fit your calibration tool into the keyhole and rotate 90ᵒ in the direction of the arrow on the device. 

Inserting the Upper Device 

Place the upper device in your mouth, as indicated in Fig. 1.

Press up on the device with both thumbs to ensure it fits securely and comfortably.

Inserting the Lower Device 

Place the lower device in your mouth.

Press down on both sides of the device using your index fingers to ensure it fits comfortably. 

Engaging the Wings 

Once the upper and lower devices are securely positioned, move your lower jaw slightly forward to allow the ‘wings ‘ to engage. Slowly close your mouth until your lips lightly touch each other (may not always create lip seals). 

Removing the Appliance

Always remove the lower device first, as indicated in Fig. 2. Using your thumbs on both sides, gently pull the lower device upward to remove it.

Using both your index fingers and thumbs, gently pull the upper device down and forward to remove it. 

  • TIP: Use lip balm during the first few nights of wearing your Dorsal to help keep lips moist.


Always clean your device in the morning immediately after removing it from your mouth.

Use a soft toothbrush. 

  1. Never use hot water; hot water damages your device and will invalidate the warranty.
  2. Never soak your device in cleaner, as it can cause delamination.
  3. After removing the device from the storage case, thoroughly brush it with a toothbrush and rinse it under cool running water.
  4. Dry all parts of the device and storage case carefully and thoroughly using a clean towel.
  5. The device should be stored in your storage case when not in use. 
  • Please note: To reduce the possibility of discoloration, do not drink coffee, tea or cola with the device in place. Always brush your teeth thoroughly before use. 

Possible Side Effects 

You may experience some temporary side effects, such as sore jaw joints, increased salivation, dry mouth, sore teeth, irritation of the soft tissues in the mouth and/or a slight change in your bite. These possible side effects should diminish within an hour of removing the device. If any of these side effects continue, contact your dentist immediately.
