Temporary Anchorage Devices or TADs

As part of your treatment plan, our expert team may suggest the use of TADs.

Temporary anchorage devices (TADs) for orthodontic anchorage are now widely accepted in everyday orthodontic practice. They are changing the way orthodontists treat some patients’ malocclusions. TADs provide a fixed point from which to apply force to move teeth. They can be placed in many different sites in the mouth. Placement is customized for each patient. TADs may contribute to predictable results, shorter treatment time and completion of active treatment on schedule. They can also be used in some cases to prevent the need for jaw surgery.

TADs are titanium-alloy mini-screws, ranging from 6 to 12 millimeters in length and 1.2 to 2 millimeters in diameter. They are fixed to bone temporarily to enhance orthodontic anchorage. Titanium alloys have been used as joint replacements and for dental implants for many years. These alloys are not rejected by the body. Orthodontists often use holding arches, also known as space maintainers, and headgear to control anchorage and minimize the movement of certain teeth while carrying out the desired movement of other teeth. TADs allow specialists to overcome limitations of holding arches and headgear and carry out difficult tooth alignments successfully. TADs can also provide a point of anchorage for patients with missing teeth.

Where are TADs placed?

TADs are placed in the bone between the roots of the teeth and can be placed in the bone in the roof of the mouth as well.

A Small Device That Does a Big Job

How is a TAD placed and does it hurt?

The site for the TAD is selected.

A TAD serves as an anchor to perform difficult tooth movement predictably

Placement is only minimally invasive and often carried out using only topical anesthetic. TADs are inserted into bone using a custom equipment. There is little or no discomfort because there are no nerve endings in the bone tissue. Once placed, our expert team is able to use the TAD as orthodontic anchorage immediately. As TADs can become loose or fall out, patients must not touch or pull the item. If necessary patients should contact us for an appointment asap.

Who places the TAD?

Because orthodontists have the training and expertise to place them, our expert team prefer, in most cases, to place TADs directly. This ensures the TAD is placed exactly where he wants it. Occasionally, our expert team may choose to have a TAD placed by another dental specialist (surgeon or periodontist).

How long are TADs used?

Our expert team will advise you about required duration. It may be required only for a few months, or it may be needed throughout your entire treatment. The device is versatile and may be used in different areas of the mouth during as needed.

Can TADs be used for patients at any age?

TADs are placed on patients who have permanent teeth. Patients with active periodontal (gum) disease may not be candidates for TADs.
