Extraradicular Temporary Anchorage Devices (TADs) are an advanced skeletal anchorage system used in orthodontics to facilitate complex tooth movements while preventing unwanted side effects. Unlike conventional TADs placed between tooth roots, extraradicular TADs are inserted into non-dental bone structures such as the infrazygomatic crest, zygomatic bone, or mandibular external cortical plates. This strategic placement provides enhanced stability, reduces the risk of root damage, and allows for greater control in cases requiring molar distalization, vertical correction, or en-masse retraction. They are particularly useful in treating severe malocclusions, open-bite cases, and patients with limited interradicular space. However, their use requires precise placement, specialized skills, and careful monitoring to minimize risks such as soft tissue irritation or implant failure. Extraradicular TADs have revolutionized orthodontic treatment by offering greater anchorage control and expanding treatment possibilities for complex cases. While they present certain challenges, their benefits in improving treatment efficiency and patient outcomes make them a valuable tool in modern orthodontics.
