The Individual Patient (IP) Appliance® was the first customized appliance system in the world and is an enhanced straight archwire technique. In the current standard in orthodontics, dentists use “straight archwire” appliances with one bracket design and one archwire for all patients, which is not always sufficient to treat all tooth movements. However, the IP Appliance® revolutionized orthodontics by allowing doctors to customize the optimal appliance for each patient.
