Can Invisalign Fix Narrow Arch?

Invisalign is capable of moving teeth but not widening the underlying jaw bone. So if the "narrow arch" is a result of malposition of teeth, invisalign may be the appropriate choice. If it is due to lack of normal bone development then Invisalign may not be effective in resolving the problem. I suggest you rely on your orthodontist's expert diagnostic opinion to distinguish between the two. That should make the choice between Invisalign and conventional braces an easy one to make!

It does widen the arch 2-3 mm by tipping the teeth outward on both sides. You may want to discuss doing a mid course correction with your Dr. during your consultation. Half way thru the case,new impressions can be taken and reset the case giving you even more ability to widen the arch..I've done it many times with good results..

Because Invisalign can expand dental arches, but is somewhat limited, see an orthodontist who uses Dentofacial Orthopedics to widen the dental arches PRIOR TO Invisalign.  This approach gets the best result for creating the fullest, most beautiful smiles without extractions and can correct your overjet as well.
