As a basic orthodontic appliance, braces are what allows us to move teeth into better positions to improve a person’s bite. In certain cases, though, this treatment application gets a little assistance from Temporary Anchorage Devices (TADs) to improve accuracy and reduce treatment time.
Braces take advantage of our teeth’s natural ability to move. Teeth are held in place within the bone by the periodontal ligament, an elastic tissue that attaches to the teeth with microscopic fibers secured by a hardened substance called cementum. The periodontal ligament is constantly remodeling in response to changes in the mouth. As pressure is placed on a tooth, new bone, ligament and cementum are formed on the “pulling” side of the tooth; on the other side, the bone and ligament dissolve (resorb), allowing the tooth to move in that direction.
Braces allow this natural process to occur with controlled forces applied by thin flexible wires threaded through the small brackets attached to the front of the teeth and then affixed or “anchored” to other teeth. By attaching the teeth to the other teeth by wires running through all the brackets, “anchorage” is created to allow teeth to be moved where the dentist wants them to go. By adjusting the tension on the wires, we can apply light but constant pressure on the “unanchored” teeth to move them into a new desired position.
Teeth we do not want to move are referred to as the anchorage for teeth we do want to move. If, however, the situation calls for more precise isolation of teeth to be moved, TADs can be very useful. TADs are mini-implants imbedded in the bone to serve as anchorage at strategic locations in the mouth. In this way, the group of teeth to be moved receives forces that are applied through the additional anchorage provided by the TADs. That “tension” or “pressure” is applied only to them and not to adjacent teeth that should not move. This increases efficiency for tooth movement and helps reduce the treatment time.
TADs can be placed using local anesthesia and with little discomfort, and are removed when orthodontic treatment is completed. Although the procedure is pretty straightforward, it does require collaboration between orthodontist and surgeon to ensure correct positioning.
In the end, TADs increase our ability to control the forces that move teeth during orthodontic treatment. This lessens discomfort for the patient and helps ensure the end result — a more functional bite and a transformed smile.

Technology for orthodontic treatments has evolved tremendously over the years. There are now more options than ever before for those seeking to straighten their teeth or fix bite issues. One of those revolutionary options is TADS (Temporary Anchorage Devices), mini-screws that can be used to more accurately control the movement and positioning of your teeth.
So, how do TADS work? Well, these very small screws are temporarily placed into the bone of the jaws to be used as non-mobile anchor units to facilitate tooth movement. They can be removed once the desired movement is complete. In addition, they can be placed using simple local anesthesia (numbing shots in the area).
The procedure is actually quite simple. After numbing the area where the TAD is to be placed, we will use gentle pressure to insert it through the gums and into the bone of your jaws. You may feel some slight pressure during the insertion, but no pain. Following the procedure, you may also feel a bit of pressure and sensitivity for one to two days, but many people experience no side effects at all. As the name suggests, TADS are temporary and usually removed after a few months, though length of time varies. Again, removing TADS also involves a quick and painless procedure.
TADS have been around for a long time, but recent refinements in the design and application procedure have allowed for more widespread use in the orthodontic office. TADS can be used for many different reasons, including eliminating the need for cumbersome appliances, such as headgear. They also offer a great way to reduce orthodontic treatment time. Finally, they allow certain cases to be treated that were nearly impossible before this technique was refined.
