Selecting the Best Size
of Tray

Impression kit

Important Before You Begin. The impression putty included in your kit should be no warmer than room temperature when used. If it is too warm, it will harden too quickly. Be mindful of where the putty is stored.

Supplies

What You Will Use. Your impression kit includes several items, but for this step you will only need the three lower impression trays.

Tray sizes

How to Choose the Correct Tray Size. Select the tray that allows the outer edges of your teeth to align with the black guideline inside the tray. Your teeth should not touch the edges of the tray and there should be space between your teeth and the tray walls.

Trying tray

Using a mirror, try each tray over your lower teeth. Choose the tray that provides the best fit with proper spacing and alignment to the guideline.

Correct size

Once you have selected the correct tray size, set the other trays aside and continue to Step 2.
