TAD
Pronunciation: tad
Also written as: TAD — Temporary Anchorage Device
Abbreviation for Temporary Anchorage Device; a small titanium screw inserted into the jawbone to provide absolute anchorage during tooth movement.
Full Definition
A Temporary Anchorage Device (TAD) is a mini-implant, typically made of titanium alloy, that is placed into the alveolar bone to act as a fixed point against which orthodontic forces can be applied. Unlike conventional anchorage, TADs are not subject to reactive movement, making them suitable for complex tooth movements such as intrusion or molar distalisation. They are removed once the desired movement is achieved. Editors should expand the acronym on first use in clinical documents. TAD should not be confused with a permanent dental implant.
Usage
Usage note: Expand on first use in all document types. Use 'a TAD' not 'an TAD' in editorial copy.
