Lip Lift Possible Despite an Overbite?

It appears that you have performed a thoughtful analysis of your condition. I would agree that the first priority is to have your orhtodontia corrected. Once that is completed you may actually notice a decrease in the size of your philtrum. IF not, then that would be a good time to consider a lip lift.

Good day! It is difficult to assess without an in person examination or at least a photo. But you are correct that your teeth and jaw alignment should be the priority. When your goals for them are achieved, then it is the perfect time to find a board-certified plastic surgeon and have an in person examination for a lip lift. Do not hesitate to contact a surgeon or your orthodontist and discuss realistic goals and your other options. Best of luck! #RealSelf100

Thank you for your question. The Lip Lift procedure is performed to accentuate the size and/or shape of the upper lip by removing skin from the region underneath the nose. As the distance is decreased between the nose and the lip, the red lip is 'lifted'. In appropriate individuals, shortening this distance may impart or restore a more favorable balance to lips and face. When there is a pre-existing bony component to this anatomic area, involving the maxilla or teeth, the issue may be complicated. You may consider having the bony component addressed first. Following orthodontic and/or orthognathic surgery, you would generally still be a candidate for a lip lift procedure. The Lip Lift planning could then be modified to accommodate your new bony anatomy.

A general principle is to correct the functional deficit first (overbite), then address the appearance.
You may find the dynamics totally altered after surgery and actually decide not to go through a lip lift.
If you decide you still want to investigate the possibility of a lip lift, I hope the video link below helps you understand if you are a candidate.

A lip lift will help correct your long philthrum after corrective orthodontic procedures. With a excessive length of the maxilla, orthognathic surgery and orthodonture may be necessary.
A lip lift by itself may not correct thin lips that lack projection. Consider Juvaderm injections or Alloderm implants to the upper and lower lips to arrive at lips that are plump and full in their appearance.

This is a great question. It brings up a very important issue that should be addressed in everyone prior to lip lift procedures. The "vertical excess" of the maxilla, or the length of the upper jawbone, may be a predominant factor in patients with a long upper lip. Lifting this lip will certainly expose more of the upper teeth. If you have this finding, then the lip lift may accentuate the problem. Once the height of the maxilla is reduced, then the lip lift may become that much more important in giving you a balanced aesthetic look.

It sounds like you have a significant knowledge base and understanding of your situation.  The more formal way to correct your problem would be to correct the underlying bony framework problem and have braces and jaw surgery.  Then evaluate the lip after.
