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. 3) Could orthodontic-surgical treatment result in a significant decrease in treatment time? However, many insurance carriers have difficulty in deciding whether such treatment should be covered.

Introduction: Because of the severity of some malocclusions, it is not always possible to treat them without a combination of orthodontics and orthognathic surgery. INTRODUCTION. 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. Since the mini-implant anchorage is used in clinical orthodontic treatment widely, [1-7] the treatment planning of orthodontic treatment changes in some aspects basically.

One indication for surgery obviously is a malocclusion too severe for orthodontics alone. ORTHODONTIC TREATMENT From Riolo, M. and Avery, J. Envelope Of Discrepancy The inner circle indicate the limits to orthodontic tooth movement ( Camouflage) alone; the middle circle, tooth movement combined with growth modification; and the outer circle, surgical correction. The amount and range of movement possible can be evaluated from Epker’s envelope of of discrepancies. Because most cephalometric analyses focus on the anteroposterior plane of space, they are often insufficient in diagnosing a significant vertical dysplasia. 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). Ujwal Gautam Achievement of a stable dentition within the bounds of physiological adaptation Limitation of Orthodontic Treatment. 2) Are the orthodontic movements required in excess of the envelope of discrepancy so that adequate orthodontic correction may not be achieved?

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). Orthognathic surgery versus orthodontic camouflage in the treatment of mandibular deficiency. Measuring millimeter distances to the ide al condylar position … Since their introduction in the field of orthodontics, temporary anchorage devices (TADs) have been widely applied in the treatment of cases that have proven difficult to treat using conventional methods. The ABO is considering several options for applying the discrepancy index to the Phase III clinical examination. Thus, compensation beyond the typical envelope of discrepancy is possible for many clinical indications.

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 . If the posterior teeth are tipped lingually, presurgical orthodontic expansion (buccal tipping) should be used; however, the tipping should not exceed 4 to 6 mm total.
