Special activators integrated into the treatment trays apply small forces to the teeth. They are applied gradually over a period of time allowing the teeth to move consecutively and in an orderly fashion.
You will be given numbered aligners that are to be worn sequentially. They move the teeth very slowly so you will be able to see the gradual movement over time as your teeth are correctly aligned.
The treatment components allow the dentist to have more control so that you will achieve an optimal end result. Most common teeth alignment and positional issues can be treated with Invisalign. There is a spectrum of possible treatment ranging from simple movements to more complex treatment plans. Your dentist will advise where you fall in this spectrum and help advise as to the best type of aligners for you.
