How to take your impression

Get ready

• Set a timer for 2 minutes 30 seconds and find a clean, flat surface to work on.
• Double-check that all the information on the bag label matches what you expect.

Test the fit

• Gently put each tray in your mouth. The right tray fits comfortably over all your teeth with a little wiggle room on the sides.
• Full coverage, comfortable fit: it may feel big, but your lips should still close comfortably over the front of the tray (picture 1).

Mix the putty. Work quickly!

Putty hardens fast. S and M trays use one set of putty; L trays use both sets.

1. Combine: mix the blue and white putty together (pictures 2 and 3) until the color is even with no streaks. Finish mixing within 15 seconds.
2. Shape and place: roll the putty into a tube, slightly thicker in the middle, and press it evenly into the tray (pictures 4 and 5).

Take the impression

1. Position yourself: stand in front of a mirror.
2. Insert and bite: place the tray in your mouth with your lips over the front of the tray. Center your teeth on the tray and putty, then bite down fully until you reach a natural stop (pictures 6 and 7). A deep bite is essential.
3. Hold still: keep the tray completely still until the timer ends. Don't move your jaw or the tray.

Remove and rinse

1. Gently remove: when time is up, loosen the tray by rocking it up and down, then slowly take it out.
2. Rinse and keep together: rinse with cool water and check that the impression looks like a full mold of your teeth. Leave the impression inside the tray.
