Abstract

Infrazygomatic vs Inter-Radicular Screws - Evolution of Direct Tads for Distalization in the Camouflage of Class 2

by Derton Nicola

In Class II malocclusions after the completion of growth, orthodontic camouflage currently represents a possible and concrete alternative to orthognathic surgery in appropriately selected cases. Through accurate control of the dento-alveolar components, achieved with distalization mechanics supported by alveolar TADs or, more recently, by “en masse” retraction using extra-alveolar skeletal anchorage, as for example the Infra Zygomatic Crest, it is possible to correct the discrepancy without intervening on the skeletal bases. This approach allows adequate function to be achieved while respecting smile aesthetics and avoiding deterioration of facial appearance, remaining within controllable biomechanical limits and without exceeding traditional biological boundaries. Orthodontic camouflage therefore represents a conscious therapeutic choice, sometimes requested by patients who identify with a compromise solution that respects their “self-concept” and who do not perceive surgical correction as necessary for their quality of life. The most recent biomechanical solutions offered by skeletal anchorage have significantly expanded diagnostic and therapeutic possibilities, making this approach more predictable, controllable, and clinically sustainable than in the past.
