Ujwal Gautam Dental study models are a cornerstone in the armamentarium used by orthodontists to both classify malocclusion and formulate treatment plans. However, many insurance carriers have difficulty in deciding whether such treatment should be covered.

A short lower face may accompany various types of malocclusions depending on the structural etiology. With the advent of TAD (Temporary anchorage devices), the possibili- ties of orthodontic treatment for the correction of various complex malocclusion has made a giant leap. 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). camouflage treatment involving only orthodontics; The middle envelope illustrates the limits of combined.

The ABO is considering several options for applying the discrepancy index to the Phase III clinical examination. Discover (and save!) With the ideal position of the upper incisors shown by the ori- gin of the x and y axes, the envelope of discrepancy 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 sur- gery (the outer envelope). 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. Envelope of Discrepancy Diagnostic Procedure. 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). With the advent of TAD (Temporary anchorage devices), the possibili- Orthognathic surgery versus orthodontic camouflage in the treatment of mandibular deficiency. Discover (and save!) One indication for surgery obviously is a malocclusion too severe for orthodontics alone. Cone-beam computed tomography (CBCT) has recently been used to obtain three-dimensional images of the craniofacial skeleton and teeth. The envelope of discrepancy denotes the limits of orthodontic treatment possible with different modalities, namely orthodontics alone or orthodontics with orthopaedics and surgical correction.

One of my favorite illustrations in any orthodontic textbook is the remarkable "Envelope of Discrepancy" developed by William Proffit and James Ackerman. Impaction of teeth usually occurs as a result of arch length discrepancy or presence of mucosal and bony barriers that prevent their eruption. 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.

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. 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. 7 Surgery preferred over Orthodontic Camouflage for; o Long Vertical Facial pattern o Moderate or severe antero-posterior jaw discrepancy o Crowding >4-6 mm o Exaggerated features o Transverse Skeletal problem 8. crossbite and severe discrepancy* This article reports the orthodontic treatment of a 14 years and 2 months old female pa-tient, presenting both anterior and posterior unilateral left crossbite, related to a transverse atrophy of the maxilla and a severe negative tooth-arch discrepancy in the upper arch.
