The palatal expander “expands” and makes your upper jaw wider by putting gentle pressure on your upper back teeth each time an adjustment is made. The animation and schematic below will demonstrate how to adjust and activate your expander. When the necessary expansion, has been achieved, you will wear the appliance for three more months to solidify the expansion and to prevent relapse.
In a bright area tip your child’s head back. You can also use an external light source such as a flash light, study light or even your cell phone to illuminate the roof of the mouth.
Place the key in the hole until it is firmly in place. The bend in the key will prevent the key to touch the palate.
Pushing the key towards the back of the mouth, you will notice the fender will rotate and the new hole will appear. The rotation stops when the key meets the back of the expander.
By pushing back and down towards the tongue, remove the key. It is extremely important to avoid undoing the turn by keeping the key in the central hole when attempting to take the key out. The next hole for insertion of the key should now be visible.
