The preference for placing temporary anchorage devices (TADs) in the mandible is primarily due to its better density and higher placement torque. The mandible's cortical bone is typically denser than that of the maxilla, which contributes to increased primary stability for the TADs. Higher placement torque is crucial because it indicates a firmer grip and better retention during orthodontic treatment, minimizing the risk of failure or loosening of the TAD.

Additionally, the denser bone in the mandible allows for a more secure anchorage point, which is essential during orthodontic movements, ensuring predictable results. This enhanced bond strength not only supports optimal loading conditions but also contributes to the long-term success of orthodontic mechanics utilizing these devices. The other options do not offer the same mechanical advantages or stability that the mandible provides, reinforcing the preference for this anatomical site in TAD placement.
