The biggest disadvantage of this type of treatment is the cost. The clear orthodontic aligners are more expensive than the other appliances. Another thing is that their use is limited. Dentists can’t use them in all cases, but only on the mild ones.
Uses:
These appliances are a great solution for people that have mild spacing or crowding. They are not recommended for severe malocclusions. For those patients, dentists have to use fixed appliances. Once you’ve talked with your dentist, he’ll be able to let you know which is the best solution for you. They are not meant for severe crowding, for teeth that require complex movements, underbites, overbites, crossbites and more.
