Temporary Anchorage Devices (TADs) represent a major breakthrough in dentistry, dramatically simplifying treatment of many orthodontic cases.

They offer easy and minimally invasive insertion and removal afterwards, an innovative approach without the need to rely on patients’ compliance, minimize the number of oral surgeries necessary, increase the types of orthodontic issues possible to treat.

IZC (infra-zygomatic crest) and BS (buccal shelf) TAD is another step forward. Placing TADs in the retromolar zone of the lower jaw or alveolar crest formation create skeletal anchorage to achieve a predictable and effective result.TADs allow distalization of the entire maxillary arch without extractions or the patient’s cooperation. Placing TADs in the mandibular buccal shelf is a reliable form of extra-alveolar support for retracting the entire lower arch to conservatively correct Class III malocclusions without tooth extraction or orthognathic surgery.

Since the IZC is a common site for placement of TADs, soft tissue irritation is a typical problem. To successfully overcome this obstacle, new DSI Zygomatic TADs have been developed. The surface of the body is a half thread, half smooth. Their unique design minimizes chances of trauma, inflammation and patient discomfort.

Extensive studies have shown that TADs result in considerably less anchorage loss than other conventional anchorage maintenance methods in patients with normal facial patterns. The use of TADs also resulted in significantly less anchorage loss in normal/hypodivergent patients than in the same type of patients where other methods of anchorage are used.DSI Zygomatic TADs are produced only from the same 6Al-4V Eli grade 5 titanium exactly like all the DSI implants. The material possesses incredible physical properties, it is stronger, lighter and more biocompatible than steel, with improved fracture toughness. Titanium is nontoxic and nonallergenic, highly corrosion-resistant. But the material’s full tissue compatibility is where it really shines. An opening in the head of the Zygomatic TAD with the diameter of 0.8 mm, is specially designed to accommodate elastic strands, ligature, and arches up to 0.21"x0.25 in diameter.

Case after case, performed by such masters of dentistry, as Chris Chang and John Lin, and hundreds of happy patients, speak for themselves. Incredible treatment outcomes in what looks like a surgical issue, but turned into a minimally invasive procedure. Watching the fantastic results is a great inspiration for many dentists.
