Temporary Anchorage Device (TAD)

What is a temporary anchorage device (TAD)?

Temporary anchorage devices or TADs are what an orthodontist uses as an anchor for braces. It helps move the teeth while patients are going through orthodontic care. The development of the TAD is one of the many important advances in the field of orthodontics that makes treatment more efficient and predicable.

Information about the temporary anchorage device (TAD).

TADs are made of a bio-compatible titanium alloy and act as miniature bone anchors which Dr. Danielle can painlessly insert into the mouth. This anchor is our leverage point and it’s how we can move teeth around. Before TADs, orthodontists who wanted to move specific teeth while keeping others still, or to achieve orthodontic movement in a mouth with missing teeth, had to rely on headgear or surgery.

What does a temporary anchorage device cost?

Our fee varies depending the severity of the case. Sometimes they are fairly cheap because it makes the treatment so much easier but usually the mouths that need a TAD are difficult cases to treat and thus end up not being cheap.

Complications for a TAD?

Typically the only one we see is that the TAD comes loose.

What is a temporary anchorage device removal like?

Not much to say other than easy. It simply screws right out and often we do not even need to use topical in the area.
