A Temporary Anchorage Device (TAD) is a temporary implant screw that we position in the mouth to serve as an anchor for moving a particular tooth or teeth; it is removed once the patient’s tooth/teeth have been successfully moved into place. A TAD can be used instead of inconvenient dental appliances like headgear and enable us to treat bite problems that are difficult or require surgery.
What Does This Procedure Involve?
To place the TAD, the patient will need to undergo a short procedure. We will numb the area where the TAD is to be placed and apply gentle pressure to insert the TAD into the gums, directly into the bone between your teeth (or in the palate, depending on the nature of your procedure).
TADs are typically a one-piece appliance made from medical-grade titanium alloy. Sometimes, before moving forward with the TAD procedure, one or more premolars will need to be extracted to create some space in the dental arch to support the TAD and corresponding teeth that are being moved. Alternatively, TADs can eliminate the need for extractions that would otherwise be necessary. Either determination will be made during your treatment planning process.
Why Would I Need a TAD?
TADs offer additional anchorage for moving teeth. In some instances, when teeth are to be directed to close a gap after a tooth extraction, anterior lip support is minimal or even poor, and Dr. Christopher McGrath will customize your TAD treatment to accommodate any variability he may face in your procedure. TADs allow the necessary anchorage to ensure that the gap in your teeth is closed.
TADs act as a direct appliance to the dental arch to help reduce the time needed for orthodontic treatment, thus reducing the chance of harmful effects of other orthodontic appliances on the teeth. If you have been advised to receive TAD treatment and want to speak with a specialist, we urge you to call Geelong Oral and Maxillofacial Surgery and schedule an appointment with Dr. Christopher McGrath. He is happy to meet with you, assess your condition, and review your treatment options with you.
