Tip the patient’s head back in a well-lit location.
Insert the key into the hole until it is securely fastened.
The key should be pushed toward the rear of the mouth. You’ll see that the fender rotates and a new hole appears. When the key comes into contact with the expander’s rear, the rotation comes to a halt.
Remove the key by pressing back and down toward the tongue. The next keyhole should now be visible.
