3.  Determine which size tray you should use.  If your mouth is large and the tray is slightly difficult to place into the mouth then it is the correct tray.  You want the back of the tray extending past your first set of teeth. Your teeth should follow the pattern in red.  If your teeth are in the blue area then the impression tray is not large enough, go to the next size.  See FIG. 2.  Fig. 2a also shows you which to use for the upper and which one to use for the lower.

4.  Take enough of the putty to fill the tray (remember you are using equal parts) (DO THE TOP TRAY FIRST) If your going to skimp out on putty material the lower is the place to do it because I only need half of the teeth showing.  The putty should be soft and there should be no plain white color showing through.  The putty changes into a different color but do not pay attention to this, if you kneading it at a steady pace it should only take about 20 seconds but make sure you do not mix for too long because it will harden on you very quickly. Do not leave the mix alone, go straight into step 5. (DO NOT PRE-MIX PUTTY, DO 1 TRAY AT A TIME)

 

5.  Place the putty in the tray do the top first. The lower tray will not take very much putty because the teeth are smaller and I only need to see the top half of the teeth .  See Fig. 3 and Fig. 4.

6.  Make sure that you do not have particles of food , i.e. brush and floss prior to taking the impression.  Place the tray all the way into the mouth and press up firmly, "DO NOT BITE DOWN ON THE TRAY" but make sure you press the tray upward/downward until the tray barely touches the tips of your teeth.   Make sure your lip goes on the outside of the tray, this is very important!!!  Allow the tray to sit in the mouth for approximately 3 minutes. When removing the tray, pull straight down, if you do not pull straight down the impression will have drag marks along the gum line.  See Fig. 5.

Note:  Do not pay attention to the height of the impression material, this is only showing you what you should see after taking the impression.
