By William F. Holt and Judith B. 3) Could orthodontic-surgical treatment result in a significant decrease in treatment time? ORTHODONTIC TREATMENT From Riolo, M. and Avery, J. Moving teeth. The precise dimensions of the envelope are much less important than the concept. The most important esthetic goal in orthodontics is to achieve a ‘‘balanced’’ smile,1 which can be best described as an appropriate positioning of the teeth and gingival scaffold within the dynamic display zone. Periodontally accelerated osteogenic orthodontics (PAOO) has been an invaluable tool in our practice for many patients who in the past would have been considered orthognathic surgical candidates, or else would have been treated with significant dentoalveolar camouflage. One of my favorite illustrations in any orthodontic textbook is the remarkable "Envelope of Discrepancy" developed by William Proffit and James Ackerman.

Proffit and Ackerman , in 1994, first highlighted the importance of “the envelope of discrepancy” and it portrays the limitations of the range for the maxillary and mandibular teeth during orthodontic treatment (inner envelope), orthodontic treatment combined with growth modification (middle envelope), and orthognathic surgery (outer envelope).

The envelope of discrepancy (Figure 1, Figure 2, Figure 6 and Figure 7) shows the amount of change that could be produced by orthodontic tooth movement alone (the inner envelope of each diagram); orthodontic tooth movement combined with growth modification (the middle envelope) and orthognathic surgery (the outer envelope). Dental discrepancies are usually treated by means of buccal tipping of the posterior teeth while skeletal discrepancies are corrected by bodily movement of the posterior teeth.
