Take both upper and lower moulds even if you only want to treat one arch. You’ll find two upper trays in different sizes and two lower trays in different sizes. You only need to make one upper and one lower mould—use whichever size fits best. Practice placing the trays in your mouth before you start. There are three putty sets: one for the upper, one for the lower, and one spare in case of mistakes.Need help? Click Here
Mix one small tub of white putty with one small tub of coloured putty quickly until they form a single colour with no streaks. It is very important to mix the putty quickly otherwise it will set before you can take your moulds. You will have about 45 seconds to 1 minute to mix the putty and place it in your mouth before it sets.
Quickly roll the putty into a sausage and using your thumbs gently push the putty into the tray. Looking in a mirror, open your mouth as wide as you can and using both hands inset the impression tray in your mouth.
Make sure there is enough putty to capture the back and front surfaces of your teeth. Aim to position your teeth in the middle of the putty sausage, then push the putty slowly over the teeth ensuring the putty goes over all the teeth and gums but your teeth do not hit the bottom of the tray. Make sure you lift your lip up to avoid it getting caught in the mould.
After 4 minutes, push your index fingers up into your cheeks until you feel the rim of the tray and GENTLY pull away from the teeth until the tray comes free. Rinse with cold water and allow to dry naturally. Do not remove the putty from the impression tray. Repeat all the steps for your lower moulds. Place your completed impressions back into the box, there is no need to wrap them in anything else.
