The mouthpiece comes pre-assembled with the smallest Size 1 straps which is recommended initially for adjusting to the device and may be all that is needed to keep your airway open. If snoring persists you should consult the instructions which contain a general guideline for the recommended strap size based on your type of bite and snoring severity. Be sure to retain all of the extra straps in case they are needed for future adjustment. Adjusting the device is detailed in this section of the instructional video (WATCH VIDEO)

Once you have determined the correct strap size to use, you should remove and replace each strap on one side at a time. To remove the strap, you must position the strap so that the strap slots align with the post keys before it can be removed. Once both ends of the strap are removed, attach the new strap by aligning the strap hole and slots over the post key one end at a time. This process should be repeated for replacing the strap on the opposite side. Please see the instructions for illustrations and guidance or in this section of the instructional video (WATCH VIDEO)

Refer to the instruction booklet which has illustrations identifying the Upper and Lower Trays or our instructional video. Both the Upper and Lower trays also have identification marks. Before molding the “UPPER” and “LOWER” markings should be visible in the impression material that you will be biting into. There are also identification marks engraved in the hard surfaces of the underside of each of the trays.

If you are new to wearing a ZQuiet Advance Mouthpiece, give it some time. It’s a normal response to eject the mouthpiece while sleeping and this will subside with time and use. If this persists, mouth tape can help keep the mouth closed and mouthpiece in place.
