Correct answer: A — Interradicular alveolar bone
Temporary anchorage devices (TADs, miniscrews, micro-implants) are small titanium screws (1.2-2.0 mm diameter, 6-12 mm length) placed into interradicular alveolar bone to provide skeletal anchorage for orthodontic tooth movement. They allow force application without unwanted reciprocal tooth movement. Common insertion sites include the buccal alveolar bone between premolar and molar roots, the infrazygomatic crest, and the palate. CBCT or periapical radiographs help identify safe insertion sites.
