TADS
Temporary Anchorage Devices (TADS) are small, screw-like dental implants made of a titanium alloy. As the name implies, they're temporary — they usually remain in place during some months of treatment, and then they are removed. Their function is to provide a stable anchorage — that is, a fixed point around which other things (namely, teeth) can be moved. But why is anchorage so important? Moving teeth in the jaw has been compared to moving a stick through the sand. With the application of force, sand moves aside in front of the stick, and fills up the space behind. The “sand” in this case consists of bone cells and cells of the periodontal ligament, which attaches the tooth to the bone. These tissues slowly move aside and reform as force is applied to them by orthodontic appliances, such as wires and elastics. TADS can also provide an anchorage point for a pushing or pulling force that would otherwise need to be applied from outside the mouth: generally, via orthodontic headgear. Wearing headgear can be uncomfortable, and compliance is sometimes a problem. In many situations TADS can eliminate the need for headgear, a welcome development for many patients. The use of TADS offers other benefits as well: It may shorten overall treatment time, eliminate the need to wear elastics (rubber bands) — and in some cases, even make certain oral surgeries unnecessary. It also allows orthodontists to take on complex cases, which might formerly have proved very difficult to treat. This small device can really do a big job! Placing and removing TADS is a minimally-invasive, pain-free procedure. After the area being treated is numbed (with an injection or other numbing treatment), a patient feels only gentle pressure as the device is inserted. The whole process can take just minutes to complete. Afterwards, an over-the counter pain reliever can be taken if needed — but many patients need no pain reliever at all. And taking TADS out is even easier. So if you're worried that it may be a painful procedure: Relax! It's far less stressful than you may think. While they're in place, TADS require minimal maintenance. Generally, they should be brushed twice daily with a soft toothbrush dipped in an antimicrobial solution. We will give you specific instructions regarding maintenance when your TADS are placed.
