The limits vary both by the tooth movement that would be needed (teeth can be moved further in some directions than others) and by the patient's age . Proffit and White developed an “envelope of discrepancy” for the jaws, describing the limits of orthodontic tooth movement alone and the limits of change possible with a treatment plan including both orthodontics and orthognathic sur- gery.

Introduction: Because of the severity of some malocclusions, it is not always possible to treat them without a combination of orthodontics and orthognathic surgery. The ABO is considering several options for applying the discrepancy index to the Phase III clinical examination. These new digital models solve many problems encountered with conventional plaster study models.

BASIC ORTHODONTIC MECHANICS AND SKELETAL ANCHORAGE To understand the indications for skeletal anchorage, the practitioner placing the devices must have a baseline understanding of orthodontic mechanics to ensure superior results.
