How Much Upper Jaw Advancement Can Be Done That Won’t Result in Facial Disharmony?

Q: Dr. Eppley, I would like to ask, in general, what is the maximum upper jaw advancement movement in mm (Lefort 1) that will not cause discrepancy between the lower and upper midface and that will not disrupt the facial harmony?

A: This is a question that would be affected by many factors most notably the shape of the face. Thus a specific answer can be provided to a general type question without pictures to understand the basis of your question.
