Using teeth as the primary anchor may have significant drawbacks. Imagine a tug-of-war between teeth; both of them will move! By using the mini-implants (TADs), the orthodontist can create a fixed, or stable, anchor.
When providing an established anchorage point for a pushing or pulling force, TADs help stabilize teeth that don’t need to move, create new directions of movement that used to not be orthodonticly available, and allow the orthodontist to control movements with less patient cooperation (like rubber bands and headgear). Compliance in wearing headgear and elastics is often a challenge that significantly effects the result of orthodontic treatment. A mini-screw system, however, is a more comfortable, less cumbersome solution to correcting this orthodontic need.
Another benefit of TADs, in some cases, is offering a viable alternative treatment option to certain types of oral surgeries. TADs have expanded the types of cases that orthodontics alone can successfully treat!
