Immerse the device in boiling water (30-45 sec), remove it, wait briefly, then bite into the softened plastic to make an impression of your teeth.

While making the impression, hold your jaw forward of its normal position. This is crucial as QuietZ. works by keeping your jaw forward during sleep.

Before making the impression, assemble the upper and lower components based on your bite type (underbite, overbite, or deep overbite). This custom assembly ensures a comfortable fit without bulky adjustments.
