“…A patient with class II malocclusion was treated with IZC screws in a case study by Ghosh et al .,[ 13 ] and a Class I molar and canine relationship was attained at the end of treatment. According to Deshmukh and Vadera,[ 14 ] precise positioning of the miniscrews in the arch is required for efficient and effective en masse distal movement of the entire maxillary dentition.…”

A BSTRACT Aims and Objectives: Mini screws placed buccal to the maxillary first or second molars in the infra zygomatic crest (IZC) region can be used as anchors for various types of tooth movement. En masse distal movement of the maxillary dentition with IZC anchorage is routinely practiced nowadays as more patients demand a non-extraction treatment and it should be evaluated. The goal of this study was to assess dentoalveolar and airway changes in individuals with class II malocclusion after en masse distal movement of the maxillary dentition utilizing infrazygomatic anchorage. Materials and Methods: This prospective study included patients who required en masse distal movement of the maxillary dentition. Following initial leveling and aligning, mini screws were placed in the IZC region, and the maxillary arch was distalized en-masse. Pre (T0) and post distalization (T1) lateral cephalograms were traced for dentoalveolar and airway changes. Statistical tests were done with SPSS software. Shapiro-Wilk test for normality and paired T test for comparison between before and after en masse distalization were done. Results: The changes in dental angular and linear measurements such as U1 to N-A, L1 to N-B and interincisal angle, U1 to N-A and U1 to point A distance, U1 to palatal plane, L1 to N-B, L1 to Apo line distance, U6 to PtV were statistically significant ( P > 0.05). Linear parameters such as L1 to ApO line, upper airway, and lower airway were not statistically significant (<0.05). Conclusion: Class II div I malocclusions can be efficiently corrected without extractions using IZC anchorage by en masse distal movement of the maxillary dentition. Significant reduction in upper anterior inclination, intrusion of maxillary anterior teeth, and distal movement of the posterior teeth were noted. No changes in airway dimensions were noted.

“…In a straight pleasant profile, the orthodontic treatment with premolar extraction can lead to flattening of the profile, which can make the patient look 5 to 10 years older than the current age. 1,2 The extra radicular placement of mini-implants or miniplates became possible with the advent of the skeletal anchorage system, which appears to be the ideal place where the en-masse retraction of whole dentition is required. Miniscrews have overcome many of these problems regardless of whether one or all of the posterior molars will be moved.…”

“…Although no special coherence is required, incisor positions and facial profiles can be well controlled. 2 Mini-implants, or miniscrews, are included as a complete suspension system for good use in orthodontic practice. Although it is common to place them in areas of the alveolar process located between the roots of the affected teeth, new sites have been proposed, called extra alveolars.…”

Here is a case report of a 20-year-old female patient with skeletal Class I malocclusion, with Angle’s Class I molar relation on the right and super Class I molar relation on the left side. The patient was diagnosed with hyperdivergent face pattern, proclined upper and lower anteriors, convex profile, potentially competent lips, short upper lip, average nasolabial angle, and anterior facial divergence. Treatment was organized by Damon System and En-masse distalization using the Infrazygomatic Crest and buccal shelf bone screws. The facial changes produced as a result of treatment were directly related to skeletal and dentoalveolar modifications that were designed as goals for patient treatment. It provided a minimal friction environment for the full-arch distalization. In this borderline bimaxillary protrusion case with a good profile, en-masse distalization turned out to be a better option than extracting the premolars and retracting incisors. It also stands out to be an example for the management of the same.

The advent of the temporary anchorage devices has revised the envelope of discrepancy in modern orthodontic practice. Orthodontic camouflage is opted in situations where the patient is reluctant to have an invasive orthognathic surgical procedure and the associated risks or where, by the use of temporary anchorage devices, the orthodontic envelope can be expanded, and optimal orthodontic result can be obtained non surgically. In such cases, TAD’s can be used to obtain an acceptable orthodontic result with a cusp to fossa posterior relation, an optimal aesthetic outcome, and a functional occlusion. This case report showcases a camouflage treatment of a Class III non-growing patient treated by use of TAD’s, to cause clockwise rotation of maxillo- mandibular occlusal complex for achieving optimum molar relation, facial esthetics, and function.A case of skeletal and Angle’s Class III malocclusion is presented where orthodontic camouflage was carried out to deliver optimal orthodontic results. This was achieved effectively by in toto distalization of the lower arch. This was brought about with the use of two extra alveolar TAD’s placed in the buccal shelf region of the lower arch. Two 2 x 12 mm bone screws were used, after space creation by extraction of lower third molars bilaterally, and elastic chains was the chosen force delivery system. Here in toto distalization of the lower arch was achieved to end in an Angle’s class I molar and canine relationship with normal overjet and overbite. Total treatment duration was of 17 months.Challenging skeletal malocclusions can be treated non surgically by effective use of TAD’s and correct and efficient use of biomechanics.
