How do Invisalign and Smile Design compare in improving jaw shape?

Hi S Thank you for your question. I am wondering if the Invisalign treatment might not take as long as usual and hence lowering the cost? Yes, in general if the case is less complex, and expected teeth movement is lesser to achieve the desired results, there would be lesser number of sets of aligners needed to complete the case. This would result in cost savings for you. However if you are comparing Invisalign to conventional braces, the treatment time between the 2 treatment modalities generally do not differ that much, but the cost for conventional would be lesser.

It is great that you are thinking about correcting your bite. With skeletal issues such as a slanted jaw, surgery is indeed required in order to achieve a good stable bite. However depending on the degree of skeletal discrepancy (slanted jaw) braces / invisalign are still options for you to consider in order to straighten out your teeth and give you a good smile. Straight and aligned teeth can be achieved but there are limitations so it depends on what your ideal smile is! My suggestion would be to consider all your options and if needed seek a second opinion.
