Distalization with extra-alveolar temporary anchorage devices in the infrazygomatic crest region

Temporary anchorage devices (TADs) placed in the infrazygomatic crest (IZC) region of the maxilla, can provide stable and reliable anchorage, enabling various orthodontic tooth movements. IZC TADs are especially useful in cases where traditional methods of anchorage, such as headgear or intermaxillary elastics, may be insufficient or impractical. These anchorage devices are particularly useful in treating Class II malocclusions, allowing for effective molar distalization. When used effectively, IZC TADs can offer a powerful and versatile solution for achieving optimal orthodontic outcomes. Their ability to provide stable and reliable anchorage makes them an invaluable tool in modern orthodontic practice, allowing for precise and efficient tooth movement in a variety of complex cases. Nevertheless, complications associated with IZC TADs are not uncommon. Therefore, careful planning and execution of treatment biomechanics is essential. CPD/Clinical Relevance: In this article, the placement of IZC TADs as well as the relevant biomechanics are addressed and a treated case is presented.
