Invisalign Instead of Orthognathic Surgery?

When there are skeletal issues, there really isn't much of a choice. Invisalign can tip teeth, but jaws and their relationships are really outside the scope of removable appliances and most bracket systems.

In my experience orthognathic surgery is necessary to alter
the jaw.  To adjust the jaw there is no substitute
for orthognathic surgery.  Invisalign is
a possible alternative to traditional braces in some patients to prepare them
for orthognathic surgery.  However, in my
opinion Invisalign is not able to address any malocclusion caused by a
misalignment of your jaw.  I recommend continuing
to use RealSelf to get additional opinions and advice.  If you decide to get a second opinion be sure
to research board certified oral maxillofacial surgeons.  Then schedule a consultation for a thorough
exam because without a physical exam is it almost impossible to give a
definitive answer on what procedure would be needed to improve the
functionality of your bite.Be well and good luck!@norrisplastic

Unfortunatley if you have skeletal discrepencies Invisalign will not address this.  Invisalign may be used to straighten and align the teeth, but the underlying skeletal deformity will not be addressed

It sounds like you have a skeletal problem where your upper jaw is too far behind your lower jaw (or the lower is too far in front of the upper).  Invisalign does not address jaw alignment problems at all, and so would not be a reasonable alternative.   Sometimes, if the discrepancy is not too great, a mild underbite can be corrected by extacting one front or two back lower teeth and using conventional appliances to pull the lower front teeth back into a normal bite.  However, this "camoflage" treatment does not actually correct the skeletal problem and will not appreciable affect the facial profile.  An experienced orthodontist can evaluate your case and discuss all the options with you.

Your orthodontist should of treated both arches when you were an adolescent. As an adult you should seek a new evaluation from an orthodontist, have them take a panoramic and cephalometric radiograph to assess what can be done to help improve your bite. Braces and the use of elastics/rubber bands can help your bite slightly, but if you have a skeletal abnormality it can only be fixed by orthognathic surgery. Your teeth sit on the bone, you can't move the bone, you can only tip the teeth.
