Braces are certainly the most recognized means for moving misaligned teeth. But depending on your or your family member’s particular malocclusion (bad bite), your orthodontist may also include other “anchorage” appliances to achieve the best results.
We can move teeth because of a mechanism that already exists in the mouth. The periodontal ligament, which holds teeth in place by attaching the tooth surface to the jawbone, allows teeth to move if needed in response to biting forces or normal tooth wear. Using braces or similar appliances, orthodontists can apply gentle but constant pressure to move teeth to new and better positions.
This applied pressure, however, soon encounters an “equal and opposite reaction,” in accordance with Newton’s third law of motion. In a way, we’re playing tug-of-war with the periodontal ligament — and as in the playground game, the key to “winning” is having the stronger point of resistance, something we call anchorage.
We often use the teeth themselves to establish this anchorage with the help of elastics (rubber bands) attached at various locations in the braces. Sometimes, though, the situation requires a different form of anchorage. In a younger patient, for example, we may want to influence the facial structure’s growth and development along with tooth movement. In this case we might use the patient’s skull for additional anchorage by having a strap running around the back of the head that attaches to brackets affixed to the teeth.
Another method involves a temporary anchorage device (TAD) directly implanted into the jawbone. We use TADs to isolate teeth we want under pressure from teeth we don’t (as with moving front teeth back without causing the back teeth to move forward). Usually made of stainless steel that won’t fuse with bone, TADs are relatively simple to remove once treatment is complete. Another form of anchorage is a titanium micro-implant, a miniature version of a dental implant that’s also inserted into the bone; like its larger relative, micro-implants fuse with the bone to add greater stability. Their diminutive size, however, eases any difficulty in their eventual removal.
Though some of these appliances aren’t visually appealing, they are temporary in nature and only applied for as long as needed. The end result, though, is permanent — beautifully aligned teeth that perform well and look great.
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.
