Will Invisalign fix an overbite that braces didn't?

Be extremely careful about the method you use to straighten your teeth because any tooth movement can cause adverse effects to your facial aesthetics, facial profile, lip support, TMJ, airway and smile. 6 month smile braces should be able to fix an overbite;  however, it will not fix an overjet. Many people confuse these two terms overbite and overjet. Overbite is the measure of how far upper front teeth overlap lower front teeth (a vertical measurement). Overjet is a measure of how far the upper front teeth are in front of the lower front teeth (a horizontal measurement). You need to be EXTREMELY careful how you choose to fix an overjet. If you have teeth extracted or do extensive interproximal reduction to fix an excessive overjet you will adversely affect your facial aesthetics. You can also cause TMJ Dysfunction and increase your potential for developing a sleep breathing disorder.Neither Invisalign or braces alone will fix an excessive overjet. The ONLY way to fix an excessive overjet is with surgery or a functional orthopedic appliance.Good luck!

You are talking about your jawline and overbite in the same sentence.  Two different things.  If your upper teeth are nicely aligned and your smile is good, the only way to make a stronger chin is to move the chin (surgery).
