Temporary Anchorage Devices (TADs) are miniscrews placed in bone for orthodontic tooth movement. These devices serve as temporary anchors during orthodontic treatment and are removed once their purpose is fulfilled. Let’s delve into some key aspects of TADs:
Purpose and Design:
TADs are small screws made from stainless steel.
They are strategically placed in either alveolar or extra-alveolar bone to provide anchorage during orthodontic procedures.
Unlike dental implants, which remain in place after orthodontic treatment, TADs are intended for temporary use.
Clinical Uses:
Extraction Control: TADs can aid in controlling the movement of teeth during extractions.
Intrusion and Extrusion: They help achieve vertical movement of teeth (intrusion or extrusion).
Rotation Correction: TADs assist in correcting tooth rotation.
Space Closure: TADs facilitate closing gaps between teeth.
Orthopedic Applications: TADs can be used in orthopedic cases to enhance anchorage.
Newton’s Third Law of Motion:
Orthodontic tooth movement follows the principles of physics. Newton’s Third Law states that “for every action, there is an equal and opposite reaction.”
TADs provide a stable anchor, allowing specific teeth to move in the desired direction.
