A temporary anchorage device (TAD) is a small, screw-like implant, typically made of a titanium alloy, that is temporarily fixed to the jawbone to provide a stable anchor point for moving teeth during orthodontic treatment. They help orthodontists achieve more precise and efficient tooth movement in complex cases.
TADs are used to provide a fixed point from which force can be applied to specific teeth, which is especially useful when surrounding teeth are not strong or numerous enough to act as anchors.

TAD's give orthodontists greater control over specific tooth movements, leading to more accurate and predictable results, especially in complex cases.
By providing efficient anchorage, TAD's can potentially shorten the overall duration of orthodontic treatment.
In many situations, using TAD's can eliminate the need for cumbersome external headgear or even some oral surgeries.
They can treat a variety of conditions, including severe overbites, underbites, open bites, crowding, and large tooth gaps.
TAD's may reduce or eliminate the need for patient-dependent rubber bands or tooth extractions in certain cases.
TADs are generally small, ranging from 1.2 to 2.5 mm in diameter and 6 to 12 mm in length, and come in various head types to accommodate different orthodontic appliances.
Primarily made from biocompatible titanium or titanium alloy, which the body readily accepts without irritation.
There are two main types based on force application to suit your specific treatment plan.
The TAD itself serves as the direct anchor point to which the pushing or pulling force is applied.
The TAD is linked to a tooth, creating a more stable anchor to move other teeth effectively.
Most are self-drilling, allowing for a minimally invasive insertion without a pilot drill.
While in place, a TAD requires minimal maintenance beyond regular oral hygiene, such as brushing with a soft toothbrush and potentially an antimicrobial rinse, as directed by the doctor. Patients should avoid hard or sticky foods in the area.
Dr. Min numbs the area, then gently places the mini-screw into the jawbone. The process is quick and generally involves only a feeling of pressure.
Once orthodontic treatment is complete, the TAD is easily removed, also typically with local anesthetic. The gum tissue heals naturally within a few days.
