Braces are a common part of many teenagers’ life experience — but not every bite problem is alike. Sometimes, there’s a need for accurately moving only a few teeth while making sure others don’t. This is where Temporary Anchorage Devices (TADs) can help streamline that effort and even reduce treatment time.
Orthodontics wouldn’t work at all if we didn’t already have a natural tooth movement mechanism in our mouths. That ability rests with the periodontal ligament, a tough, elastic tissue between the teeth and the bone that firmly attaches to both with tiny collagen fibers. Though quite secure in holding teeth in place, the ligament attachment also allows teeth to move in response to changes in the bone and jaw structure.
Braces are made of brackets cemented to tooth surfaces through which tiny wires pass. The wires are anchored, usually to other teeth or groups of teeth, and tightened to apply pressure against the other teeth. The ligament does the rest: as the teeth are “pressured” to move in a certain direction, new bone, ligament and an anchoring substance known as cementum forms behind it to secure the tooth in its new position.
The anchorage teeth are not intended to move. In some situations, though, it’s difficult to keep them from not moving — much like trying to keep a boat anchor from not dragging through sand on the sea bottom. TADs help alleviate this problem: it’s a mini-screw or mini-implant that’s temporarily placed in the jawbone to which the tension wire can be secured. They’re placed in the best positions for isolating the teeth that need to be moved without compromising the position of nearby teeth that don’t.
With the site numbed with a local anesthetic, we install the TAD through the gum tissue into the bone with a special device; their screw-shaped design holds them securely in place. They’re then removed when the orthodontic treatment is complete.
While a simple procedure, precise placement requires collaboration between the orthodontist and the oral surgeon or dentist who installs them. They also need special attention during daily hygiene to keep them clean. Still, with difficult bite situations they can help bring about the right outcome — a straight and beautiful smile.

When they’re introducing a new movie, actors often take a moment to pay tribute to the people who helped make it happen — like, you know, their dentists. At least that’s what Charlize Theron did at the premiere of her new spy thriller, Atomic Blonde.
"I just want to take a quick moment to thank my dentists," she told a Los Angeles audience as they waited for the film to roll. "I don’t even know if they’re here, but I just want to say thank you."
Why did the starring actress/producer give a shout-out to her dental team? It seems she trained and fought so hard in the action sequences that she actually cracked two teeth!
“I had severe tooth pain, which I never had in my entire life,” Theron told an interviewer from Variety. At first, she thought it was a cavity — but later, she found out it was more serious: One tooth needed a root canal, and the other had to be extracted and replaced with a dental implant — but first, a bone grafting procedure was needed. “I had to put a donor bone in [the jaw] to heal,” she noted, “and then I had another surgery to put a metal screw in there.”
Although it might sound like the kind of treatment only an action hero would need, bone grafting is now a routine part of many dental implant procedures. The reason is that without a sufficient volume of good-quality bone, implant placement is difficult or impossible. That’s because the screw-like implant must be firmly joined with the jawbone, so it can support the replacement tooth.
Fortunately, dentists have a way to help your body build new bone: A relatively small amount of bone material can be placed in the missing tooth’s socket in a procedure called bone grafting. This may come from your own body or, more likely, it may be processed bone material from a laboratory. The donor material can be from a human, animal or synthetic source, but because of stringent processing techniques, the material is safe for human use. Once it is put in place your body takes over, using the grafted material as a scaffold on which to build new bone cells. If jawbone volume is insufficient for implants, it can often be restored to a viable point in a few months.
Better yet, when grafting material is placed in the tooth socket immediately after extraction, it can keep most of the bone loss from occurring in the first place, enabling an implant to be placed as soon as possible — even before the end of a movie’s shooting schedule.
Will Atomic Blonde prove to be an action-movie classic? Only time will tell. But one thing’s for sure: When Charlize Theron walks down the red carpet, she won’t have to worry about a gap in her smile.
